Broken computer

Two weeks ago my computer got hit with a nasty virus. I managed to have it remotely removed by the manufacturer. 4 days later I got the same virus and this time the remote repair didn't take hold. So last saturday I took my PC to my nearby Staples to get it fixed. I got the PC back yesterday. It's fixed, sort of. But there are some quirks that I'm dealing with which may explode on me. We'll see what happens.
