Starting sometime last week (my Avast Home Edition 4.8 updates daily), when I boot up my computer Avast warns me that the file “C:\Windows\system32\ati3duag.dll” is malware of type Win32:Trojan/gen. I think this is a false positive because that file has been in my laptop since new and Avast never complained before until last week. The file is one of the drivers for my Asus F3JA laptop’s ATI Mobility Radeon X1600 display card. And I’ve had my laptop and Avast installed on it for years now.
After Avast quarantined the file I couldn’t get it to move back to its original location, so I deleted it from the virus chest but then my laptop completely blacked out on restart (of course, because there’s no more display driver!). I had to re-install everything using my laptop’s recovery CD. Then after a fresh installation I get the same warning from Avast about ati3duag.dll being malware again. So this confirms my belief that the warning is a false positive. There is the possibility that the file is already infected with malware when it came out from the manufacturer but this is pretty slim.
Can someone at Avast rectify this? Otherwise it’s pretty annoying that this warning pops up everytime I turn on my laptop.
