Both a corrupt profile and what I used to see happen with another expired antivirus.

1. I do not suggest Adaware today. Besides it is not an antivirus.
2. Try another account on this PC and report the findings.
3. Uninstall that old antivirus and install one of the many free ones such as Google's google pack (it has one or 2) as well as Avast, Free AVG.

Good luck,
