I suggest you “quarantine” the old data for as long as possible- the longer you leave it, the less likely it will contain a virus that hasn’t been added to anti-virus definitions- then scan it again avast! and the Kaspersky online scanner.

Other programs on your computer may need updating- especially Sun Java, as older versions have security vulnerabilities.
