The "zeus" virus, whenever i would do anything on the internet it would pop up with a box saying "Hello! Zeus is here", whenever i would click on anything on the net page it would pop up again. I ran a scan with mcafee but it didnt find anything, so we did a system restore and now the pop up boxes have gone. I fixed the mcafee scan thing, but its still not finding anything. My computer seems to be running better now too. Would the system restore have got rid of the zeus thing? Its all running fine now..
I would still follow the instructions that I previously posted for you and keep an eye on your computer to see if it continues to run ok. It is possible the system restore may have taken care of your problem but it still may be there only to resurface some day.

Normally System Restore, if successful, is the easiest way to thwart an infection as long as you then make sure that Windows and McAfee, and anything else that is time-sensitive, are updated.
Also it is advisable to temporarily disable System Restore to delete the infected restore point.
