i cant install my antivirus software
that is scary !!!!
what problem did you have?
what a/v are you using? if a paid version have you asked them for help?
there are several good free versions out there, avg/avira/avast
you need a working anti virus
that error message can happen if you made a change in partition size.
i use a dual booot system and any changed in a partition ( add/remove/resize) will cause that
i think the aol browser is a modified I.E. ( at least it was years ago)
was that system ever running XP?
