We can possibly find something in Old Version.com
for Avast or Avira.
The problem is related to McAfee. It could be that it is corrupt, or just can't get the correct DAT files for 98.
What version of McAfee is being used?
Found this on Avast. Avast works great on Windows Vista, Windows XP, Windows 2000, Windows NT, Windows 95/98*123Runner and also on 64 bit operative systems. Avast
