I am helping a friend deal with his malware infested PC. He already took it to a Famous Electronic Store (the Best place to Buy stuff) and asked the geeks to fix it. One week and two hundred dollars later, it is still infected with the same scareware and hijacker... so now it's up to me. Yikes! 
I am leaning toward pulling his personal files, wiping it, and re-installing the OS. He has only the usual factory recovery disc.
I would like to use my retail x64 disc to install the OS, and put in his product key when activating it. Will that work?
