2. Click Properties.
3. Click the System Restore tab.
4. Check the box beside "Turn off System Restore".

To Turn System Restore back ON.
1. Follow the above Steps 1 to 3
2. UNcheck the box beside "Turn off System Restore".

Then do another scan with your virus scanner to see if you are still being alerted to anything.
I use IE and Outlook Express for all things Internet.
Bad idea - change to Opera or Firefox/Thunderbird
