I had installed a program I thought I wanted to run and then decided to delete it. I went in to drive c and deleted it from the program files and anything I could find related to it. I deleted the shortcut icon from my desktop. Now when I first boot up, the computer searches for the shortcut, which is not there. So where else do I need to go to delete that and stop getting that search box at boot up?

Also, why do I get a lot of "illegal operation" boxes and it closes my program? Could that be a virus? It has done that for about 3 weeks now. We do not open any forwarded email, but could we have possibly picked up one anyway? Thanks for the help!
