Hi Vickie,
When you attempt to remove these problems, don't just switch off system restore, do everything in safemode.
Get adaware SE from www.lavasoft.com
ie.
1. Switch off system restore
2. Reboot in safemode
3. Run your antivirus scan
4. Run adaware scan
5. reboot when all cleaned
6. Don't forget to switch system restore back on.
You may be left with one or two problematic viruses/trojans, but at least it will be a lot less work to remove them manually.
Try symantics website for step by step instructions for removing particular viruses
