Goodbye Malware

We went over to a friend's house this evening so I could help fix some problems they've been having with their computer. Last Friday I had run a bunch of malware and virus scans, and did a bunch of cleanup, and it seemed to have worked, but after only a day the problems were back. Random popups and webpage link redirects and blocked sites. So it seemed the only way to fix it for good was to reinstall the operating system. So first, all their data had to be backed up, but their computer had only a single hard drive and they had no external backup solutions. Luckily, they had an old computer they were no longer using, so I was able to pull the hard drive out and use that. It was like 5 in the morning before it was finally ready to be used. Thankfully, they were both night owls like myself.
