===============Use a Firewall
:Install and use a firewall with outbound protection
While the firewall built into Windows XP is adequate to protect you from incoming attacks, it will not be much help in alerting you to programs already on your PC attempting to connect to remote servers
I therefore strongly recommend that you install one
of the following free firewalls: Sunbelt Free Firewall
See Bleepingcomputer's excellent tutorial to help using and understanding a firewall hereNote:
You should only have one firewall installed at a time. Having more than one antivirus program installed at once is likely to cause conflicts and may well decrease your overall protection as well as seriously impairing the performance of your PC.
=============================Delete\uninstall anything else that we have used.System Restore
Then I will need you to reset your System Restore points.
The link below shows how to create a clean restore point.
