I suppose the target is the browser and the email. I haven't used W98 in a long, long time. But I had a call from an elderly client who hates Vista so she abandoned her new computer in favor of her old W98 box and she's been told she is "sending out viruses." We exchanged emails so I could see if anything seemed to irritate my AVG (which it did not).
I'm out of the area for another two weeks, so I thought I'd use my idle time finding out what's available. The best thing will probably be to try to make peace between the lady and Vista. I don't like V either, but I wouldn't go back to 98 -- probably would go to XP.
Anyway, I would use Free AVG for her, but I think I understand from the AVG Forum that it will not install on older than XP-SP2.
P :-)
