system restore sucks. personally, i disable it, in any system that supports it. one solution would be to disable it. then you can get rid of the virus. if you have an antivirus it should detect it. if not, then delete the folder. by the way. there is program around the net that searches for the specific virus, and deletes it. it is similar the one for the "klez" virus, you should probably find it somewhere in the symantec site.
