actually, this is the only AV that i used so far since upgrading to Windows 7. i didn't have problems with it since installing it back in May.. until now, that is. heck, i used Avast as my only AV as well when i was still using XP.
also, downloaded a new setup file and i tried running it and this comes up.
"C:\Program Files\AVAST Software\Avast\Setup\setiface.dll is either not designed to run on Windows or it contains an error"
i already ran a SFC scan and there aren't any problems with the file system. also did a full system scan and there aren't any threats.
and all my programs run fine. but strangely enough, Avast still seems to function. it runs, all the protection shields are running.
the update is the only problem.
anyway, i'll give the uninstall utility a shot.
