Avast 4.8.1356 Problem

I have several PC at home with Avast v4.8.1356. During a routine scan yesterday suddenly all of them come up with virus warning and inflected files. A lot of the files have been in those PC for several years (mostly Reflexive downloaded games). Many of them are said to be inflected with either Win32:Trojan-gen or W32:Malware-gen.

I submit some of them to virusscan.jotti.org and www.virustotal.com for multi-engine scan and most of them came up clean with all other scanners except Avast (and GData also for some files). So should I believe in Avast along and not the other 20-30 engines?

Is Avast’s signature or engine have a major/sigificant upgrade recently? I’ve been using Avast for the past 2-3 years how come it never scan out any of virus as the files been there all those years?!

Is it possible that there is some sort of error in Avast’s engine or virus database??!!!

Hello IM,

Yes! the false detection is accepted. gdata uses avast engine as one of its engines.

please send all detected files to virus@avast.com . you can send them in password protected zip files with the password in the body of the mail and subject as false positives with the avast version - that is 4.8.1356.

the fps are because of the modification in detection of -gens. hope fully everything will be fixed. read the whole topic starting from this post : http://forum.avast.com/index.php?topic=49196.msg420115#msg420115
