I want you to run your PC as normal for a few days and when you are happy that everything is fine, do the following:
Update your anti-virus program,
Disable System Restore,
Boot into Safe Mode,
Scan your computer for viruses.
When you get the all clear, reboot into Normal Mode.
Re-enable System Restore,
Create a Restore Point.
This will give a clean Restore Point should you need it in the future.
A tutorial for System Restore is available here.
The reason for waiting is that if removing the malware has caused a problem, which it occasionally does, you can put your PC back to how it was before the fix. This will re-install the malware, but an infected PC is better than an expensive paperweight!
Some bedtime reading: This is a very good tutorial about keeping your computer safe and secure on the internet.
