I am unable to double click on any application icons. If I do, I get the RED error window letting me know that there is no associated file. I believe that I caught a virus causing this issue. I have ran multiple anti virus and scanning programs and have determined that I have cleaned the system. I just need to fix the issues, possibly with the registry. Anyone able to help? I am running a Sony Vaio Laptop Windows 7, Intel Core 2 Duo. I was just using the computer as is, but wife just bought me a Apple IPAD and I cannot install I-Tunes, and assume that this is a related issue.
