About 5 years ago I did a fresh install on my laptop and created an OS image (OS and docs on separate partitions). And I stayed clean for 5 years. Now I have something pretty nasty and I'm out of practice on what to do. I thought I could just apply my OS image from 5 years ago, let XP do it's update thing overnight, and update AVG and Firefox and be back in business.

But no such luck. After applying the OS image, I immediately notice some really weird behavior. I've tried Microsoft Security Essentials and the latest Firefox build but I get lot of browser redirects. And it doesn't seem like Windows Update will run. And when I try to view my local hard disk config under the computer management console, the local drives won't show up.

I know I could re-install the OS, but I'm afraid that if this this thing is in the MBR, I'll still have it.

Thanks for your help in advance.
