Since you have removed the malware, you should now remove all the old infected restore points.
Instructions on how to do that are in the link below if you need them. http://www.bleepingcomputer.com/tutorials/windows-xp-system-restore-guide/
Remove temporary files, logs, cookies, etc. by using Ccleaner. Do not use "Advanced Settings" or the "Issues" button. Use only the default settings. http://www.ccleaner.com/
Glad it worked for you! Good luck to ya.
You may have gotten infected by just visiting a website. Using Firefox Browser with the NoScript addon will protect you from
"driveby" installs of malware.
