Hi ePost:
Thanks for your help!
Yes, I have the latest version of CCleaner installed.
I don't run chkds and scannow regularly, but will now. I did the chkdsk and it repaired one thing. When I try to run scannow, I get an error that scannow is not found.
I ran the Secunia PSI and it found 4 things to update regarding QuickTime, Macromedia Flash, Mozilla Firefox, and a Retrospect program (for external backup drive).
I don't think re-installing IE will help, since I already did this and encountered the same "post-CCLeaner" problem with IE.
Cheers,
Dragonegg
