I use it because it scores high on reputable av tests, but I don't trust the wallet feature, I don't like automatic license renewal, and I will not use the included registry cleaner. Registry cleaners are notorious for bricking PCs. If some company made an av product that tests well and is not bloatware, that is what I would use.

Works fine on windows 8 or 8.1 with no problem. Have used Bitdefender for the past 3 years with no problems. Compared all of the other companies and always return to Bitdefender.

Does not install in Windows 8.1... it's crap

Chosen as antivirus product of the year.2013 (AV Comparatives)
Always at or near the top for real-world protection.
Resource usage is much improved and now is one of the best.
My only problem is it makes my internet connection spike.

Only a stunned monkey would give this a 1.

Maybe the best rated AV solution but caused this multi-core PC with 8 GIG Ram to slow to a crawl & at times to lockup totally, therefore from my point of view it's useless.

* Overcomplicated and somewhat cryptic UI slow and somewhat buggy. Tray icons are nearly useless..mouseover tells you what their doing but NOT what their doing it to. Gadget has no labels and mouseover hardly ever pops up descriptions. Avast! does control interfaces right, the industry should learn from them.
* Seems to detect more infections than others but most are heuristic-based. So its either finding a LOT of malware or a lot of false positives.

Tends to get great ratings from AV labs, but the UI really hobbles it.

the worst

na123451 reviewed v10.2 on Jan 21, 2010

I have used bitdefender for a few year now. I haven't has too many issue, however, over the past year I have had two major virus attacks that bitfender didn't catch. The viruses where known viruses that were out for some time now. I emailed and post messages to the bitdefender support and I never received any reply back. BitDefinder has failed at being a anti-virus tool and as a company in regards to support.

I agree with all those critcicising Bitdefender. It wouldn't be worth the 20 euro to do everything they ask me to do to help fix their horrible software. Never again. It slows stuff down, it gives you messages about updating stuff you don't want. It fails to update. Customer support is awful It is truly abysmal. it didn't used to be bad a few years ago - but it is now. Do not purchase.

I just got done becoming disgusted with BitDefender Internet Security 2008. I don't know why this posting hasn't been updated, but I did try the latest version.

The AV has good detection, yes. But there were so many serious bugs I just couldn't stand to keep using it. For one thing, each time an application needed to connect out, the firewall would alert to the DNS attempt (a good thing), but would not put up an alert on the connection attempt itself. Invariably, the application would time out, and the connection would fail--except for the rare application that offered to retry the connection. Serious firewall flaws. I've never seen such an issue in any other.

The firewall alerts have "A" and "B" as accelerator keys. This means that if you happen to be typing when an alert appears, you can very easily accidentally (and unknowingly) Allow or Block a program's connection attempt. This is not far-fetched; it actually happened to me within a half hour of running BitDefender Internet Security 2008 (fortunately, it wasn't malware that was accidentally allowed).

The anti-spam component didn't work at all with Thunderbird on my system. Oh, the toolbar was there in the message windows, but none of the emails I received were scanned, the email/spam counts remained at 0 the entire time, and the spam test string (from the BitDefender readme) wasn't detected. Serious anti-spam flaws.

I noticed huge, random slowdowns. Sometimes, running Thunderbird took eons. Sometimes, merely deleting a message in Thunderbird took eons. Not always. Fun stuff, this randomness.

By default, BitDefender doesn't update if a scan is running. The problem is that if you start a scan, then stop it and close the scan window, it thinks the scan is still taking place--until you restart BitDefender or reboot. This means if you start a scan and then cancel it, BitDefender won't update itself until you restart. Serious updater flaws.

This is the worst program I have ever used!
I gave me dozens of false positives that kaspersky and NOD32 never found.... I rate it zero.

I currently use Kaspersky but it doesn't play nice with other security programs like outpost, Spyware doctor or Spybot. Bit defenders gets good reviews in independent testing and leak tests and I find no driver conflicts with this program as opposed to Paspersky or Outpost. As far as Nod32 is concern, it is a good free program but when compared to the ones you have to buy it doesn't fare as well.
