When I run a full system scan on Spyware Doctor, it works fine until I try to 'Fix Checked', and then my desktop and taskbar disappears. I tried ctrl+alt+del and it showed that Spyware Doctor was not responding. I thus had to end task. This does not happen when I do a quick scan on Spyware Doctor. The number of infections found was 2185. Help! I paid for Spyware Doctor and don't want my money to go to waste if the infections can't be deleted!
