You could try to initiate System Restore to before this happened. If successful then temporarily disable System Restore to delete the bad restore point.
These 'infections' are fake anti--malware which rely on a person clicking anything that pops up to activate. They bypass most if not all antivirus applications because of the way they behave.
There are tools available to combat them however.

how do I initiate a system restore?
I don't know the details of your system etc but it's more or less the same for all.
Start > All Programs > Accessories > (System Tools - Vista/Windows 7) > System Restore
That's assuming it's turned on of course. If it isn't don't bother to turn it on until the infection has gone.
Proceed with that link.
Google searches are useful getting this sort of information.
ok thanks, when I clicked on system restore the following message popped up on his pc...
"Windows cannot find 'C:\Windows\system32\rstrui.exe. Make sure you typed the name correctly, and then try again"
I guess I will need to try the link instead...
That shows that whatever this infection did it has corrupted certain Windows functions.
What is the operating system and service pack? Right-click Computer (My Computer XP) and select Properties. It will tell you there.
