Featured review

I had read various reviews about bitdefender antivirus, so I decided to try it. This was the worst antivirus I have ever installed. It bogged down my computer to the point, where I could not even do a google search. It would take almost 20 minutes to boot up. There tech support kept having me install patches. It was one problem after another. Customer service would not issue me a refund even though their product does not work correctly. After 2 months I removed it from my computer, without any refund from the company. My computer is now running smoothly.

I believe that the only reason Bitdefender keeps its share in the antivirus software market is because it is heavily advertised and promoted by several "information technology oriented" sites. Having been convinced about its high capabilities I installed the free edition of it several months ago. It kept popping up messages prompting to buy the full version all the time until the trial expired and it (appeared to have) stopped running its antivirus service, leaving the computer vulnerable to any threat. I tried to uninstall and switch back to my previous av software, without success. I used a removal tool for the case, still some components of bitdefender were left in my system. I had to switch back to a windows restore point to get my computer working and get rid of the obviously unwanted software. STILL, after all the trouble the service (gzserv.exe) is running in the background and I can't stop/remove it, as well as the registry keys associated with bitdefender AFTER the uninstallation/removal! The message I get is that I have to have Administration rights to do so. Funny thing, my account does have administration rights and actually is the only administrator in my system. Bitdefender certainly won't let go. Defends every last bit it gets its teeth on. Stay away or vivere pericolosamente.

I agree...I installed Bitdefender because it was supposed to be the highest rated and the fact I could us the same license on 3 computers was an added bonus and no one could beat the price. But it is the WORST antivirus ever. My computer constantly hangs now since installing it. The virus scanner takes DAYS to complete. The service itself will just shut itself down leaving the computer vulnerable to attack and the only suggestion it gives is to restart as if to say this is a normal thing.

Several antivirus software installed on the same computer can lead to PC slowdowns or even crashes, so this is what probably happened in your case. However you should try BitDefender 2010, it was only released in August and it was really appreciated by reviewers. If you have BitDefender only for 2 months your license key is still valid so the upgrade is free of charge.
