Hi, thanks for responding. Yes, it deletes anything that I try to download, Hazelnut. Derek, it's very possible it's something else causing this. I have Microsoft Security Essentials but I've read that there are fake versions out there, so I'm hoping I didn't end up with one of those. That does run every week and I also run the CCleaner periodically. BUT, I have noticed that the security package that came with my pc has been disabled and I cannot re-enable it, so possibly there is a virus of some kind on here. I feel like I know so little about computers that all these technical do-it-yourself things I keep reading to fix the problem are beyond me. I guess I may have to break down and actually buy an anti-virus software.
