I am using the windows vista on mine system. Recently, my computer has detected a virus or something nasty that I cannot place. I caused the problem with most of my programs will not open. When I try open the any program it give option of “open with”. I thought it would a system restore because it has worked before in the past to get rid of these problems, but not a single problem with it - System Restore is one of the three quarters gives me the "Open With" option. I tried a couple of different methods to solve this problem - including the troubleshooting page - but nothing works. Can anyone help me to just get open again, and who can fix things there?
