Hello everybody! I got requests from people who follow me on YouTube and today we are going to test BitDefender Free Antivirus 2011 I have previously installed the software I kept the default settings And as always, nothing has been changed This version comes with Antivirus, antiphishing and automatic update enabled Other options are only available for paid versions of BitDefender Let’s update database with last signatures As you can see this version offers real time protection It seems to me this is new because 2010 version did not offer real time protection Database is update Lets now check computer’s resources usage These three services here Are from BitDefender It uses about 12 MB of RAM memory A low memory usage for an antivirus Here I have a list of malicious links and let’s start testing This toolbar was installed by BitDefender This is Windows firewall That was detected by the web filter from BitDefender That is a rogue software That was also detected by the web filter That was also detected by the web filter That was also detected That was also detected That rogue software seems not to be detected by BitDefender That was detected By the web filter I think this is a rogue software That was also detected by the web filter That is also…no this link is not working That is also dead And that was also detected by the web filter Considering that most of the links were detected by the web filter from BitDefender I will now download these files on my host machine and then I will bring them for this virtual machine And see if the Antivirus engine really detects them I will pause recording now and I will return with these files Hi everybody! Here I am back I downloaded the files from the links used on this test We have to consider that if some of these files were received as email attachments Web filter would made no difference Let’s see now if BitDefender detect them I will enable real time protection And let’s scan now with BitDefender this specific folder As this analysis may take some time, I will return at the end of this process with the results At the end of scanning process of the folder six infected objects were eliminated by BitDefender And two unresolved items These files are left. Let’s run them That is Copy Cat, a rogue, has already installed I believe this has also been previously installed RealGIF is also here I will now start a full scan of this computer with BitDefender and I will return at the end with the results At the end of BitDefender scanning process seven threats were found All of them were removed Let’s move this spyware detected here to quarantine I will restart the computer now, then I will run CCleaner and I will return with the results from Malwarebytes At the end of Malwarebytes scanning process 17 infected objects were found Trojan Z.bot Spyware.MarketScore Trojan Z.bot again And the Adware.RelevantKnowledge As a registry key Let’s remove all of them As there are no malicious process running on memory right now it will not be necessary restarting the computer I will now start scanning with both SuperAntiSpyware and Norton Power Eraser and I will be right back with the results At the end of SuperAntiSpyare scanning process Nothing was found At the end of Norton Power Eraser scanning process Many suspicious files were found I will finally do a scan with Hitman Pro and I will return at the end of the process with the results At the end of Hitman Pro scanning process Nothing was found Well, my verdict about BitDefender Free Antivirus 2011 As positive aspects we can point out: low memory usage and the excellent detection of its web filter As negative aspects we can point out: the fact that it did not detect some trojans like Z-bot, for example, and some rogue softwares Therefore, must improve its heuristic module to face this kind of threat Well, that is all for today.
