I did a custom scan. I have some old files on Drive E. It detected 98lite as a virus.
It say threat: BV:ExitWindows-M [Trj] 98restor.bat, 98se2me.bat, 02res.bat,03.bat, 03rest.bat, 05res.bat,Read1st,txt
Those I know are not viruses. The 98lite company wouldn’t do that.
I also have a program called MozBackup. It backups up your Mozilla profiles. Avast is reporting a file in the SeaMonkey 2.9.1 (en-US) - 2012-05-26.pcv archive as a decompression bomb. The file in the PCV archive causing the possible false alert is called places.sqlite
One comment, I haven’t be able to do current updates (Do to being on dial-up). So the Avast definitions files may be too old.
