Bitdefender is one of the best antiviruses on the market in 2021.

Bạn đang xem: Đánh giá bitdefender

It provides advanced malware protection & a ton of additional internet security protections, all inside an intuitive sầu user interface.

Bitdefender scored excellent detection rates in all of my malware tests, identifying nearly 1,000 malware files without slowing down my computer. And Bitdefender’s website protection detected far more phishing sites than built-in protections from Chrome, Firefox, or Edge.

Bitdefender also has more additional features than almost any other antivirus (& all of the extras work really well). Bitdefender has:

System optimization.Ransomware protection. VPN (virtual private network). Password manager.Parental controls.Webcam & microphone protection. Anti-theft protection for Windows and Android.

Most of Bitdefender’s features work great — the system optimization tools cleared up a lot of space on my PC và improved my device’s performance, the VPN is comparable in speed & performance to standalone VPNs, và the parental controls are highly customizable and even include location tracking and geofencing. I also think it’s amazing that Bitdefender’s anti-theft protection works on Windows devices – most competitors lượt thích McAfee và Avira offer anti-theft on Mobile devices only.

Bitdefender is also surprisingly affordable. Even if you nâng cấp khổng lồ the premium VPN & get a good standalone password manager, Bitdefender’s Total Securityplanis still cheaper than most competitors.

But as much as I lượt thích Bitdefender, I can’t say it’s without flaws. Bitdefender’s password manager is too basic — it doesn’t even have sầu two-factor authentication or password security auditing. The di động ứng dụng for iOS is also very limited, providing only web protection & simple email breach monitoring. And the VPN that comes bundled with all of Bitdefender’s plans is limited to lớn 200 MB data per day (but users can upgrade lớn Bitdefender’s premium VPN, which is powered by Hotspot Shield, provides excellent speeds, and has servers in 30 countries around the world).

Overall, Bitdefender is one of my favorite mạng internet security products.It’s got lots of really good features, it’s easy to use, and it’s pretty cheap. And all of Bitdefender’s packages come with a risk-không tính phí 30-day money-baông chồng guarantee.

Bitdefender Security Features

Virus/Vulnerability Scan

Bitdefender’s antivirut scanner is both thorough và lightweight.It uses a huge malware directory and machine learning khổng lồ detect both known and emerging malware. And because most of the malware scanning takes place in the cloud, Bitdefender’s antivirut engine takes up a fraction of CPU & disk space during scans.

Bitdefender offers 4 types of scans:

Quichồng Scan. A lightweight scan of core system files and temporary files where viruses are often stored.System Scan. An in-depth analysis & scan of the entire system for malware và vulnerabilities.Custom Scan. Scanning in any system location where there might be potential threats. Vulnerability Scan. Scanning for privacy risks in application settings as well as critical software updates.

I tested Bitdefender’s vi khuẩn scanner by hiding nearly 1,000 malware samples throughout my virtual Windows computer, including viruses, worms, trojans, adware, spyware, rootkits, ransomware, cryptojackers, and keyloggers — once my system was fully infected with malware, I performed a full system scan.


Bitdefender’s full system scan took just under 1 hour to complete — this is comparable to lớn top competitors such as Norton và Avirawhose scans take around 45 minutes to complete.

However, unlike most competitors, Bitdefender has a minimal impact on system performance. I didn’t notice any slowdown on my system throughout the entire scanning processeven other premium competitors lượt thích TotalAVcause some slowdown during full system scans.

Bitdefender also lets users schedule scans — you can choose between several scheduling options, including at system startup, daily, weekly, and monthly. However, users can only schedule custom scans — Norton, Avira, TotalAV, and BullGuardall provide easy, one-cliông xã scan scheduling for all types of scans.


Overall, Bitdefender’s malware scanner is one of the best on the market— it’s fast, it doesn’t cause slowdowns, and it has perfect malware detection rates. If you’re looking for a lightweight, powerful antivirut scanner, Bitdefender is an excellent choice.

Real-Time Protection

Bitdefender’s real-time protection (Bitdefender Shield) actively scans every file & gmail attachment the moment you access them. Bitdefender Shield’s default settings include the following scans:

Potentially unwanted applications. Software that hides inside other applications (usually bundled freeware).Network shares. Issues in remote networks on your device.Boot sectors.Issues that may change the boot sequence.Only new & modified files.Threats that may hide in new và changed files.Keyloggers. Malware that captures keystrokes.

While Bitdefender Shield’s mặc định protections are good enough for most users, advanced users can customize real-time settings lớn also include applications, scripts, và archives. Advanced users can also choose to exclude any of the options mentioned above sầu.


For my testing, I downloaded around 100 infected .exe samples, .txt files, and .rar files (compressed folders), and I also ran network-based attacks from my Android & another PC.

Bitdefender’s real-time protection blocked every single malware file before I could tải về it.But Bitdefender Shield didn’t merely interrupt my downloads — it wouldn’t even allow me to lớn start them, greying out the “Save File” button.

Overall, I’m really impressed by Bitdefender’s real-time protection.Some competitors provide similar real-time malware detection rates, but Bitdefender provides the best customization options on the market for its real-time scanner.

Anti-Phishing/Web Protection

Whenever you visit a trang web, Bitdefender’s anti-phishing protection compares it against a regularly updated database of millions of dangerous, blacklisted sites. If there’s a match, Bitdefender blocks access lớn the site.

I tested Bitdefender’s anti-phishing protection with a huge directory of phishing sites — Bitdefender blocked all of the kém chất lượng websites I tried lớn access.Chrome, Firefox, & even third-tiệc nhỏ anti-phishing tools from competitors like Panda và Kasperskyfailed to detect as many suspicious sites as Bitdefender.

What’s more, Bitdefender features a convenient notification screen, so you can see what websites it has blocked & why.This makes it easy to permanently add a false positive sầu lớn Bitdefender’s exception danh mục. Whitelisting sites can be done in one cliông chồng, whereas other antiviruses such as Nortonrequire you to dig through settings and advanced protocols to lớn whitedanh mục safe sites. However, keep in mind that you should only whitedanh sách sites if you are absolutely certain that they’re legitimate và don’t contain malware.


Bitdefender’s web protection also prevents you from accessing a webpage that contains downloadable malware — it also checks search results for dangerous sites, scans encrypted websites, and checks sites for fraudulent content.

Overall, Bitdefender provides exceptional anti-phishing protection as well as protection against a wide range of other web-based threats.In addition to blocking more phishing sites than most competitors, Bitdefender also makes it easy to whitedanh mục websites & adjust web protection settings.

System Optimization

Bitdefender’s “OneCliông chồng Optimizer”scans your system and removes unnecessary files from your device — including:

Temporary system files.Windows junk files.Recycle bin files.Broken registry items.Browser history.

I ran the scan with no other applications running in the background, and it only took around 2 minutes to complete.

Bitdefender managed to không lấy phí up a total of 1.3 GB from my PC, which is really good.


However, Bitdefender’s tuneup tool has some annoying limitations — for example:

Before clicking “Optimize,” Bitdefender recommended that I đánh giá the issues it had flagged. But Bitdefender didn’t let me view the details about those issues. For example, it flagged one broken software location in my registry options, yet it wouldn’t let me see the tệp tin name or date. This was frustrating because I wanted to lớn know what I was deleting, not just the location of the file in question.

I’d also like to lớn see more features included in Bitdefeder’s system tuneup tool. For example, TotalAV’sbuilt-in optimization includes a startup manager, an application uninstaller, và a duplicate file finder.

That said, afterrunning Bitdefender’s one-cliông chồng optimization, I noticed a speed increase on my PC.This simple one-cliông xã method for freeing up space does have sầu some limitations, and it’s missing some features that competitors provide. But overall, it’s very convenient and does a good job.

Secure Web Browser (SafePay)

Bitdefender’s secure website browser, SafePay, is a great way lớn keep hackers from stealing your personal information when making online transactions.

Here are the main benefits of using SafePay:

Prevents hackers from remotely accessing your desktop.Stops you from taking snapshots of your screen.Utilizes Bitdefender’s password manager khổng lồ protect your passwords.Emulates a virtual keyboard lớn prsự kiện keystroke tracking.Turns on built-in VPN protection (200 MB daily limit).

I wanted khổng lồ show off SafePay’s protections, but I couldn’t capture any screenshots due to its built-in screenshot-blocker, which is great — if you can’t screen-capture your browser, then neither can intrusive sầu hackers!

I tested SafePay with my PayPal tài khoản. Apart from being unable to lớn use any of my screen capture tools, I was even unable to copy-paste my password or 2FA codes while using SafePay! The virtual keyboard popped up the moment I was asked to lớn enter my login details, keeping keyloggers from recording my password or personal info.

However, pages loaded pretty slowly, and I couldn’t stream HD Clip with SafePay — it’s definitely not designed to replace your web browser. But for anyone that does business online, SafePay is a really good privacy enhancement tool.

If you’re looking lớn protect your information as much as possible during online transactions, SafePay is a really good addition to Bitdefender’s already impressive sầu web protection toolkit.

Password Manager

Bitdefender’s password manager is simple và secure— but it’s not as good as dedicated password managers like Dashlane or 1Password.Bitdefender doesn’t provide features lượt thích two-factor authentication (2FA), password vault auditing, or sharing between accounts. However, it does provide the essential functions of a password manager, such as:

Multi-device sync.Unlimited password storage.Auto-save & auto-fill.Separate password vaults.Password generator.

When you first run Bitdefender’s password manager,you follow three simple steps khổng lồ create a password vault (or “wallet”):

You name the wallet and choose a master password (you can also enter a master password hint).You choose which devices to lớn sync your passwords with.You choose what website browsers you wish lớn import passwords from. Supported options include Internet Explorer, Mozilla Firefox, & Google Chrome.


For users that mô tả a computer with other people, there’s no limit lớn how many wallets you can create, which makes it easy lớn make separate password vaults with a single Bitdefender trương mục.

Bitdefender’s wallet lets you store passwords, identities (personal information, addresses, and phone numbers), credit cards and ngân hàng accounts, email credentials, license keys and logins for software, và Wi-Fi passwords.


To be able khổng lồ auto-save sầu and auto-fill passwords, you need to install Bitdefender’s password manager browser extension. Both the auto-save và auto-fill functions worked well during my tests. The auto-save feature automatically saved my login credentials whenever I logged inlớn new sites, but I didn’t like that I was unable to lớn disable auto-save for specific sites.

Dedicated password managers like LastPass ask you whether you want lớn save login credentials for each new online account. Bitdefeder’s auto-fill feature automatically filled my login credentials for saved sites, but again, there wasn’t an option khổng lồ disable auto-fill for some sites. The best standalone password managerslet users disable auto-fill for some sites — this is especially useful for banking sites. That said, Bitdefender does have sầu its own browser that makes online banking very secure.

Bitdefender also has a pretty good password generator, but you can only access it from the web extension. The generator’s default password length is 15 characters, but users can generate passwords up khổng lồ 255 characters long. This is pretty great considering that LastPass only generates passwords that are up lớn 99 characters long. By default, Bitdefender’s password generator generates passwords with lowercase letters, uppercase letters, và digits, but you can customize settings to only include one of these options. You can also enable special characters & generate passwords that are easy to lớn pronounce.


Overall, Bitdefender’s password manager is convenient, but it’s not quite as good as standalone password managers like Dashlane, 1Password, LastPass, or Keeper, all of which offer a wide range of additional tools, lượt thích password sharing, password auditing, dark web monitoring, 2FA, biometric logins, và much more. That said, Bitdefender’s password manager is a well-made digital wallet for users that don’t really need an advanced password manager tiện ích.

Bitdefender VPN

Bitdefender’s VPN is powered by Hotspot Shield, one of the more popular VPN providerson the market. However, Bitdefender’s VPN has a much smaller hệ thống network & it doesn’t provide the same cấp độ of functionality as Hotspot Shield. That said, Bitdefender’s VPN covers all of the basics — it uses unbreakable encryption, has a no-logs policy, và it even comes with a kill switch.

All Bitdefender plans come with a không lấy phí version of this VPN, but it’s not very good.Bitdefender’s miễn phí VPN picks a random VPS based on your location, & it only includes 200 MB of browsing per day — barely enough to lớn watch a single YouTube video clip.


However, users that nâng cấp lớn Bitdefender’s separate VPN subscription get unlimited browsing data as well as access to 30 servers around the world.And Bitdefender’s premium VPN has some of the best speeds of any antivirus’s VPN on the market— it’s even faster than some standalone competitors.

Here’s a comparison of my internet connection before và after activating Bitdefender’s VPN on a local US server:


As you can see, there wasn’t a noticeable difference in internet tốc độ. This is especially good when compared khổng lồ VPNs from companies lượt thích Kaspersky,which can cut your tải về speed in half and sover your PING skyrocketing!

Of course, most users want khổng lồ know if a VPN will give access khổng lồ geo-restricted streaming nội dung — unfortunately Bitdefender failed all of my geo-bypassing tests.I’m in the US, so I tried khổng lồ access Netflix’s UK library using a UK hệ thống, và Netflix immediately detected that I was using a VPN. The same happened when I tried khổng lồ access BBC iPlayer. I tried a lot of other different countries & streaming services, but every site noticed that I was using a VPNvà wouldn’t let me access different nội dung libraries.

On the other h&, Bitdefender is really good for torrenting— you can even mix the VPN khổng lồ auto-connect whenever you start a peer-to-peer sharing phầm mềm. This is in complete contrast with Norton, which doesn’t even let you turn on its VPN if you have a torrenting client installed on your PC.

Overall, I like Bitdefender’s premium VPN. While it doesn’t have a lot of the features that standalone VPNs provide, Bitdefender still provides surprisingly fast connection speeds và good encrypted browsing for users that want to lớn increase their internet security.

Parental Control

Bitdefender’s parental control app is available as a separate download for Windows, macOS, Android, & iOS.

I tested the parental control app on my PC & Android. To set up Bitdefender’s parental control app, I navigated to lớn the Privacy tab in the desktop phầm mềm, and then I clicked on Configure under Parental Advisor. This took me khổng lồ Bitdefender’s online portal, Bitdefender Central, where I first had lớn add a child. Next, I had to lớn install the Bitdefender parental control app on the device my child would be using — I had khổng lồ give the ứng dụng all sorts of permissions on the mobile device, but this didn’t take me longer than a couple of minutes.


Next, I had to customize the parental app’s settings. In Bitdefender Central, I could:

Set daily device limits (not available on iOS). Set device usage schedules.Manage (allow và block) apps. Whitelist và blackmenu specific sites or categories of sites (not available for iOS).View location and mix safe & restricted areas (available only on Android & iOS).View the lachạy thử phone contacts added to lớn the contact danh mục (available only on Android and iOS devices).

After configuring all of the settings, I tested the tiện ích with a friend. My friover tried visiting dozens of websites that belonged khổng lồ the blacklisted categories, & Bitdefender’s parental control ứng dụng blocked her from accessing each of those websites. The content filters really impressed me — competitors lượt thích BullGuardoffer a ton of options for filtering websites but don’t accurately bloông chồng most inappropriate content. The only thing I dislượt thích about Bitdefender’s trang web filtering is that there’s no way for your child to ask for access lớn a specific trang web via the app.

All of the other features inside Bitdefender’s parental app worked perfectly — I could see how much time my friover was spending on her mobile phone, view which apps she accessed, và accurately track her location. I was impressed that I could ask my friend khổng lồ send me a notification when she arrived safely at a specified location — this isn’t something that most competing antiviruses with parental controlsoffer!


I also really like that Bitdefender allows geo-fencing, so you can get alerts if your child leaves a pre-determined safe area.


I was also impressed at how accurately Bitdefender tracked my friend’s location.Norton can track children within a 65 foot radius, but Bitdefender pinpointed the exact house my friend’s phone was in.

Overall, Bitdefender’s parental controls provide some of the best protections of any parental control tiện ích out there—parents who want to lớn make sure that their kids are as safe as possible, both online and in the real world, will find a lot of value in Bitdefender’s parental control phầm mềm.

Additional Features

Bitdefender is one of the most feature-rich internet security suiteson the market in 2021, & the features I previously described are just a small part of its entire offering.

Bitdefender also has:

Firewall — Adjusts network settings based on whether you’re connecting khổng lồ a dynamic network, a home/office network, or a public network. There’s also a “Stealth mode” that makes your device invisible.Ransomware remediation — Identifies when ransomware tries khổng lồ encrypt some of your files và quickly makes a backup copy of those files.Webcam and microphone protection— Lists apps that request access to your webcam and/or microphone. Users can whitemenu & blackdanh sách specific apps.Wi-Fi protection— Analyzes Wi-Fi networks and routers for potential threats.Anti-tracking protection— Prevents website trackers from collecting your data for advertising and other purposes.Anti-theft — Shows you the location of your device on a bản đồ. From Bitdefender’s online portal, users can remotely loông xã, sound an alarm, or wipe a stolen device.File shredder— Permanently deletes files or folders.Profiles— Users can manually or automatically adjust Bitdefender’s settings based on activity/apps in usage.

While all of these features work great, my favorite ones are anti-theft protection and user profiles. Some competitors like McAfee and Avira offer anti-theft protection, but for thiết bị di động devices only. Bitdefender, however, provides anti-theft protection for Windows computers, too. I tested this feature on my PC, and I was really impressed at how accurate Bitdefender’s location tracking was — it pinpointed my exact address on a maps. I also found it easy khổng lồ remotely lochồng my PC, & I was pretty surprised at how loud the anti-theft alarm was!

I’m also a huge fan of Bitdefender’s user profiles which include work, movie, game, public Wi-Fi, và battery mode profiles. If you’re a gamer & worried that an antivirut will interrupt your gameplay, you’ll be happy khổng lồ learn that Bitdefender’s gaming mode is pretty good. The moment you start playing a game, Bitdefender will suspend notifications, automatic Windows updates, & vi khuẩn scans. Bitdefender also has an excellent game booster which improves your gaming performance — although Bitdefender’s game booster isn’t as good as BullGuard’sgame booster.

Overall, Bitdefender has a truly impressive range of features— if you’re looking for an antivi khuẩn that has almost all of the internet security tools you can think of, Bitdefender won’t disappoint you!

Bitdefender Plans và Pricing

Bitdefender offers 3 annual plans — but only its premium Total Securityplanworks across all operating systems. All of the plans include a limited VPN, but Bitdefender’s premium VPN is available at checkout, & it costs less than most competing standalone VPNs.

Bitdefender’s không tính phí plan is one of the better miễn phí plans on the market, although it does have a lot of limitations (lượt thích all không tính phí antiviruses). All of Bitdefender’s paid plans include a risk-không tính tiền money-baông xã guarantee for 30 days.

Bitdefender Free — Good Free Plan (With Real-Time Protection for Windows Users)

*Not available in some countries*

Bitdefender does offer a free version of its app for Windows, macOS, và Android. While it lacks important protections lượt thích ransomware protection, a firewall, và a secure web browser, the không tính tiền version includes:

Antivirus scanning.Real-time protection (Windows only).Web protection (Windows only).

BitdefenderAntivirus Free Editionuses the same advanced anti-malware engine as the premium version — which earned Bitdefender a spot on our best freeWindows antiviruses of 2021.

While Bitdefender’s miễn phí version lacks a lot of the protections that make Bitdefender’s premium plans so good, I still think Bitdefender Antivi khuẩn Free Edition is a decent choice for Windows users who are only looking for malware scanning. Plus, unlượt thích most competitors, Bitdefender’s không tính phí Windows antivi khuẩn also has real-time malware protection.

Bitdefender Antivirut Plus — Basic Paid Plan (Windows Only)

Bitdefender Antivi khuẩn Plus includes real-time malware defense và website protection, as well as:

Multi-layer ransomware protection. Secure browser for online finances.Password manager. Wi-Fi protection.VPN (200 MB daily data).Anti-tracking protection. User profiles (including gaming mode).File shredder. 24/7 customer support.

Bitdefender Antivirut Plus is a good entry-cấp độ antivirut plan, but it’s lacking a couple of essential security features, lượt thích a firewall. I’m also pretty disappointed that this plan is only available for Windows computers, especially when competitors like Norton, McAfee, and TotalAV include coverage for all operating systems in all of their plans.

Bitdefender Antivirus Plusis cheaper than most competitors’ entry-level plans, and it also has an excellent discount for the first year. Bitdefender Antivi khuẩn Plusis backed by a 30-day money-back guarantee.

Bitdefender Internet Security — Advanced Paid Plan (Windows Only)

Bitdefender Internet Security comes with all of the features included in Antivirut Plus,but it also adds extra features like:

Firewall.Anti-spam filter.Webcam and microphone protection.Parental controls.

Bitdefender Internet Security isa really good value, but it’s only for PC users. The biggest downside of this plan is that it doesn’t offer multi-platkhung support — if you use an Android, Mac, or iOS device, you’ll have sầu khổng lồ upgrade to Bitdefender’s most expensive sầu plan.

However, for Windows users, Bitdefender Internet Security is one of the best options on the market — it covers up lớn 3 PCs, includes a ton of features, & is pretty affordable.

Bitdefender Total Security — Premium Paid Plan

Bitdefender Total Security has all of the features included inInternet Security,plus:

Coverage for Mac.mobile apps for iOS and Android.System tune-up tools.

Bitdefender Total Securitydoesn’t offer a lot of improvement for PC users (besides the one-cliông chồng system tune-up tool), but thiết bị di động users will want to upgrade lớn Total Security so they can get access khổng lồ Bitdefender’s excellent di động apps.

While Total Security doesn’t have a VPN with unlimited data lượt thích many premium antiviruses vì chưng (lượt thích Norton), Bitdefender’s most advanced plan provides comprehensive security for up to lớn 5 devices for a really low price — even if you buy the separate VPN subscription, Bitdefender’s premium package is still cheaper than most competitors.

Bitdefender’s Smartphone App

Bitdefender’s mobile apps for iOS and Android come included with the Total Security package, but they’re also available as standalone subscriptions.

Here’s what’s included in Bitdefender’s Smartphone phầm mềm for Android:

Antivirus scanner.Web protection (Chrome, Firefox, Opera, Edge, Brave, and others).Autopilot (automatic security recommendations).App loông xã.Anti-theft protection.Data breach monitoring (email only). VPN(200 MB/daily with unlimited VPN available).Smartwatch compatibility.

While Bitdefender’s Android app is very good, its iOS ứng dụng is surprisingly limited. The iOS phầm mềm only has web protection, data breach monitoring, & a free VPN. To be fair, iOS devices can’t get viruses, so iOS users don’t need a virus scanner. But I’d still lượt thích to lớn see Bitdefender expvà the functionality of its iOS phầm mềm to lớn better meet the internet security needs of iOS users (like the best antiviruses for iOS do).

For my tests, I downloaded several malware files and pirated apps lớn my Samsung Galaxy, & then I installed Bitdefender’s Mobile antivirus on my phone.

When I set up Bitdefender di động Security,the ứng dụng immediately recommended I persize a scan. The scan took only a minute, & it found all of the malicious files I placed on my phone.


Next, I tested Bitdefender’s website protection by visiting dozens of malicious sites with Chrome’s security filter turned off.Bitdefender’s web protections blocked every single phishing site I tried opening, including sites that Chrome’s built-in protections failed khổng lồ catch during my tests.


I also tested Bitdefender’s tiện ích loông xã feature — it allows you to lochồng important apps with a 4-8 digit PIN or your device’s biometric scanner. Bitdefender even takes an automatic selfie when somebody toàn thân tries và fails khổng lồ unlock your phone or locked apps — I locked my Facebook ứng dụng, deliberately entered the wrong PIN code 3 times, và then I received a notification in Bitdefender’s online portal that someone tried to unloông chồng Facebook on my sản phẩm điện thoại (& yes, Bitdefender did take my selfie as well!).

Another cool thing about Bitdefender’s tiện ích loông xã feature is that you can enable Bitdefender to randomize number positions on the keyboard so that no one is able to lớn read your PIN code.


Bitdefender’s anti-theft feature is also great — enabling users khổng lồ send alerts, loông xã the device, take a picture of the thief, và wipe the device directly from Bitdefender’s online portal. I tested this feature both on my Windows PC & on my Android phone, & it worked perfectly on both devices.


Overall, Bitdefender’s di động app is one of the best di động security apps on the market, providing excellent antivi khuẩn protection và a couple of very useful extras, including ứng dụng locking and anti-theft protection.

Before you download Bitdefender, you’ll need to lớn create a Bitdefender Central tài khoản online và download the Bitdefender install files from there —it took me less than 5 minutes lớn mix up my trương mục & get Bitdefender up và running on my PC.

As soon as I launched the application, Bitdefender gave sầu me a quiông chồng tour of the software and suggested I run an initial scan.


Bitdefender’s desktop dashboard is really well laid-out, with large, simple buttons, a comprehensive sầu toolbar, và every feature accessible with just a few clicks. I love sầu that there’s a customizable Quiông chồng Action button on the main screen, so users can easily add more buttons khổng lồ the dashboard. You can only have sầu 5 “Quiông chồng Actions” on your trang chính screen at any one time. But these can always be edited & changed.


All of Bitdefender’s essential và extra features are located in 3 tabs: Protection, Privacy, và Utilities.

In the Protection tab, you can enable/disable website protection, vulnerability scanning, firewall, ransomware remediation, & antispam. Each of these features can also be customized — although Bitdefender’s mặc định settings are good enough for most users.

Bitdefender’s Customer Support

Knowledge database.Email tư vấn.Phone tư vấn.Live chat support.Community tư vấn.

I was especially impressed with Bitdefender’s live chat support. I always connected lớn a live sầu chat agent within minutes, and each time they answered my questions within a few seconds. As far as customer support for an antivirut goes, this is the quickest I’ve sầu ever seen.


Bitdefender’s phone support is impressive sầu, too. Bitdefender has 28 different phone numbers across 18 countries, including a worldwide phone number with 24-hour service.

I called the United States number, & Bitdefender connected me with an agent almost instantly — which was a big surprise! I’m used to being put on hold for at least a few minutes with most tech companies.

I asked the agent about the different subscription packages, and he quickly broke them down & recommended which one I should go with based on my needs. I’m always impressed when a customer tư vấn person gives me good advice instead of simply telling me lớn spover my money on the most expensive option — Bitdefender’s phone support representative was knowledgeable, personable, and helpful.

If you don’t want lớn connect with a customer tư vấn person, Bitdefender’s knowledge base has a vast collection of articles as well as đoạn phim tutorials.I found that I was able to get most of my questions answered through this knowledge base.

Is Bitdefender the Top Protection for Windows/Mac?

Bitdefender is a svào contender for best antivirus in 2021. Bitdefender’s advanced malware engine detected every piece of malware in my testing — including newer and advanced threats like cryptojackers, rootkits, và ransomware. Bitdefender’s website protection also caught most of the phishing sites I tried visiting — outperforming both the majority of competitors và the most popular browsers, including Chrome và Firefox.

I wish that Bitdefender would add a few more security features lớn its password manager, and the không tính phí VPN bundled with the software is way too limited. Also, the Smartphone ứng dụng for iOS could use some improvement.
