Avast update falsely flags good apps as malware

Czech Republic-based Avast issued an update late on Wednesday to its antivirus software that mistakenly flagged hundreds of innocent files as a Trojan. It fixed the situation five and a half hours later.

Falsely labeled as malware were programs from Adobe, Realtek, sound card drivers, and various media players, among others, according to a blog post on the Avast Support Center.

The errant update had been issued around 12:15 a.m. GMT. A new update was issued at 5:50 a.m. GMT that corrected the problem. Customers who did not use their computers between that time will most likely not be impacted, the company said.

The software was identifying the good files as the Win32:Delf-MZG Trojan, according to Avast.

Avast, based in Prague, did not respond to an e-mail late on Wednesday seeking comment.

False positives happen in the industry. In July, Computer Associates' antivirus software was falsely tagging a Windows XP system file as a virus, and last year AVG falsely identified a file from security provider ZoneAlarm as a virus.

Yea sure. :tooth:

Well I remember the time AVG had falsely identified a file from security provider ZoneAlarm as a virus. At that moment I was usin AVG Free. Although as far as I remember, the AVG free users were not troubled by the problem, but that was the time I decided that I'll kick AVG soon. And now I see myself with ESET, on a fast computer as opposed to slowin the PC down by AVG, and more safe.

Generic signatures sometimes can cause s**t..... 1 signature for a entire "family" of malware.... but 1 signature and a F***cked computer. For what i read, alot of people got screwed with this. People who power off/restarted the PC while the AV is using the bad definitions have PCs unable to boot because important files is under quarantine. This remember some time ago, when kaspersky is screwing PCs too detecting explorer.exe and other system files as malware.

I would sugggest you go for eset, you can get keys for it that would last for 5 months or so, you can even use a fix so that changing of keys will be automated. I suggest you check this out ESET V4 Fixes

I believe eset and kaspersky are both on the same level when it comes to protection. Also any other questions you have regarding eset fixes please post it on that link I gave you because we are a bit off topic here. :think:

It really depends on your needs. I use ESET for it's speed and simplicity. I've never use Kaspersky though. ESET is very low on system. It doesn't hog the system. It's runnin fast on my P4 2.66GHz. ;)

Kas is fast but not as fast as ESET if I believe my friend's reviews.

But if you wanna use Kaspersky there is a trial reset on the frontpage by box if you want it. ;)

Go here for KAV - http://www.nsanedown.com/?request=1975149

OR For KIS - http://www.nsanedown.com/?request=4138992

After openin the page, there would be a icon and text named "Trial Reset (courtesy of box)". Click on it and download it. There must be instructions to use it in the file. ;)

Avast isn't that bad. It's free AV is great for the ones who don't want to pay.. 1 mistake doesn't make an app some useless cr*p. It would cause problems yea, but if this is the first time for such thing it isn't a reason to switch, :rolleyes:

So true. If you see... they offer the most complete free product. With the addtion of Heuristics in the version 5, detection will increase (it already is good). It cover all the "normal" attack vectors (file shield, web shield, mail shield, p2p shield, IM shield, network shield and the new behaviour shield in V5). All this for free. For the non tech people, is a great solution. And take this point too: If Avast release good free version, the other companies have to improve their free prodcuts too, to not lost market. SO the user have much to gain. Even ESET do mistakes. Take a look when ESET launched V4: alot of bugs and people with problems. Some users still using the V2. Not wanna to upgrade. Perfection not exist. Is all about personal experience.

@ ravisoorya

If KIS is working for you, still with it. If you wanna..... take a look at the HIPS module and put it to work like a anti-executable. Run your Browser under the sandbox module and you are ready to go. Controlling execution is a good step to protection. Look at rogues, droppers and this type of stuff that come through driveby downloads.... need execution... control it and even if the KIS signatures not catch the malware.... it cannot run. Cannot run, cannot infect. If the browser is virtualized, emptying the sandbox will erase all the signs of the malware.

take care
