I am an amateur computer user, so bear with me if I do not get all the terms correct...
I have this black box on my desktop that I cannot remove, no matter how many times I run Virus Scan, Ad-Aware, or any other spyware removal tool. It is not a pop-up--IT WILL NOT DISAPPEAR! If I click on it, it installs SpySherriff. I cannot change my display, and both virus scan and SpyBot show that my computer is clean. HELP!
