I'm not sure if this is the right place, but I have to start somewhere. Last week (4/17) I tried to boot up my PC, but it wouldn't take. After several diagnostics of memory and hardware (with no ill results) I finally gave in. Took it into a local computer shop. When checking for the problem, they came across several corrupted files. They also came across a message from Norton about a virus and for the user to contact a special number. Since I couldn't boot the PC, I never got to see this message. After $125, my PC is cleaned and back in action. Was this unique to my PC or some common problem last week. Just trying to find out what went on.
