I'd boot to a live cd to get my data off to remote media. Then do a reload of the OS. Be sure to scan all removable drives with good a/v antimalware software.
The xp disk can run sfc.exe maybe from barts.
A barts cd can be used to access a restore point if you want to try that.
The second issue is how you were able to get a virus. It might take some best practices to help avoid them in the future.
The only other way is to try to fix what you have with a xp cd using it's repair or a live cd to fix what is going on and try to get it back to some unknown point.
I love norton ghost.I make a good image after I get all the apps and updates in. In 20 minutes I can return it to that state.
