Editors' Review


Bitdefender Antivirus Free offers strong basic protection from computer viruses, malware, rootkits, and emerging threats. It's lightweight and unobtrusive, partly because it doesn't pack on extras like identity and privacy protection that other tools can provide, and partly because it lacks some of the automated features and support options that come with Bitdefender's premium antivirus solutions.


Less is more: Bitdefender Antivirus Free is refreshingly free of the "extra" features and tools that make some apps unwieldy and confusing for non-experts.

Easy to use: Bitdefender's compact main interface is a glorified system tray pop-up. We could toggle the Virus Shield and Auto Scan features, access an optional My Bitdefender account, and open the Logs, which also manage Events and Quarantine lists.

Auto Scan: Bitdefender's proprietary Auto Scan feature saves time and resources by focusing attention on high-risk areas. You can disable Auto Scan in the interface's Configuration Area.

Virus Shield: The optional Virus Shield scans files, Web pages, and data in real time to keep malware at bay.


Incompatible: Bitdefender Antivirus Free doesn't share power with other antivirus freeware like Microsoft Security Essentials.

Installation issues: Bitdefender's installer offers to remove conflicting programs, reboot, and resume setup, but we had to reboot and finish the installation manually.

Bottom Line

Plenty of free antivirus solutions offer nearly as many bells and whistles as premium packages. If you just want reliable antivirus protection that doesn't require a lot of attention, Bitdefender Antivirus Free belongs on your short list.

"Really Good For Laptops"

January 10, 2015  |  By Bighugs1965

 |  Version: Bitdefender Antivirus Free


Light and fast.
Auto scans and updates.
Has some HIPS features.
Effective and free.
A true set and forget antivirus.


Minimalist to the max.


A lot of laptops are not on at any particular time or schedule. This makes it hard to schedule scans and make sure an antivirus is updated. That's where this little gem comes in handy. It is smart enough to scan automatically when it knows you are on. This is done in the background and is almost unnoticeable. It will also auto update it's virus database. It does more than just protect against viruses and spyware. It will protect against bad websites and much more due to it's HIPS. I never notice any system slowdown or anything. I am more than satisfied.

Just need to add this. I've been using this for almost a year and no problems. It has phishing and mall ware detection for web sites. If you use any software that also does the same (some browsers, Adblockers etc..), then they may cause some slowdowns in browsing. Easy remedy...disable those features and let Bitdefender do it. that way there are no conflicts of two or more softwares doing the same redundant task.

"Fair enough as a temporary solution"

December 27, 2014  |  By harl

 |  Version: Bitdefender Antivirus Free


It's free and it seems to work and recognize a lot of potential threats, it scans relatively fast, stays in the background and is barely noticeable, and it's easy to use since it basically doesn't have any settings (which, with many background scanners, may often seem redundant or presumptuous and lead people to choose unnecessarily strict and extensive settings).


The same aspect is deprecative though, because it's too simple and too obscure when I'd actually *want* it to have at least a few options, as well as show me the files it scans when it does a full system scan (as all it does is stating that a scan is scheduled and that's it, when it's actually already scanning).
Another draw-off is that its Virus Shield module interferes with any direct downloads - those that are downloaded and immediately saved sequentially without preallocation. As soon as such a download is initiated (e.g. by Firefox or the .net API), Bitdefender tries to access and read the same files, making it a lot more complicated for programs to keep authority over those files.


I only just realised this after having annoying issues with downloading files for a few weeks - sometimes a download would work, which was because the file as a whole got downloaded into memory first, then allocated and saved in one piece, but whenever I just clicked a link that would usually start an immediate download and sequentially save the data to disk, it would just idle for a few seconds and then fail. As soon as I disabled Bitdefender's "Virus Shield", that whole issue went away.

I've been using Bitdefender for years and I still keep the free Bitdefender around as a handy alternative, mainly because it's free and relatively up-to-date (though its on-demand scanner tends to mistakenly find threats in certain files that aren't harmful at all).

Altogether though, I wouldn't recommend this program. Firstly, its interferences with procedures that shouldn't be of any concern to it, which makes it obscure to people *what* it actually does - nowhere does it ever say that it scans files *as* they are downloaded. Secondly, the lack of settings, information and an intuitive interface is contrary to the extensiveness of its background activities - it actually safeguards certain files, it doesn't safeguard others, the user doesn't know about the differences and there's no way to choose anything, like a heuristics level or how actual threats are being handled. Instead it just does what it does per default, and in case of a supposedly harmful file, it automatically quarantines the file, but doesn't actively tell the user about it and it's rather unintuitive to access the few functions or choices it offers - certain buttons only showing when moused over, and the interface isn't very informative overall.

Performance, memory and raw usability: 5 stars
Frequent updates: 5 stars
Threat recognition: 4 stars
Overall efficiency: 4 stars
Clean uninstallation: 4 stars
System integration & interference: 3 stars
Interface, comfort and interactiveness: 2 stars

- It needs a better GUI (more options, more info and dialogues, less blackboxing)
- It shouldn't ever try to cut off other programs from accessing any files, unless it actually finds a threat, and if those files are locked it shouldn't try to force access
- False positives shouldn't happen, unless the heuristics level can be chosen

"Too Good to be True"

November 14, 2014  |  By flavouride

 |  Version: Bitdefender Antivirus Free


It's Free with no nags or ads, and feature-rich:-
- Based on The paid version which is a top dog which beats most of the other commercial products
- Frequent Antivirus & Detection Engine updates - at least 5 times a day
- Intelligent File Shield - automatically repairs or quarantines known threats
- Intelligent Web Shield - automatically blocks access to malicious web contents and doesn't require additional BHOs or other browser add-ons
- Intelligent HIPS aka Antispyware or Program Firewall - automatically blocks internet access for badly behaved programs
- Anti-Rookits
- The x64 version is a full amd64 suite which gives no trace of a single 32-bit process in the Task Manager
- Virtually no adverse effect on Windows and other program start-ups and shut-downs
- Extremely low memory footprints


- Under-advertised and under-documented: doesn't say what it does, the official Bitdefender Free Antivirus download page is the only place which states all its features
- This Free version is not submitted for independent AV labs for certifications, it's difficult to believe before seeing some stats, one can only depend upon the company's reputation
- Ultra slow initial deep sweep - took 4 hours for a 250GB HDD yet found 0 threats although subsequent deep sweeps took only 42 minutes


For a reputable, free and feature-rich AV suite one can hardly ask for more, but hope someone can publish some real test results for this free version
