Phony pop-up alert boxes, background changes or "balloon" pop-ups from the tray (by the clock) about a trojan, virus or spyware infection and the attempt to sell you some useless software to "fix" the problem usually indicates that your computer has a Smitfraud infection. DO NOT DOWNLOAD OR BUY THE PRODUCT THEY TRY TO SELL YOU! IT IS SCAM. It is really extortion-ware, first they infect your machine, then they want $$$ to remove it.

Sounds like your computer may have a variant of this ubiquitous Smitfraud infection.

Almost all "general purpose","all-in one" spyware and virus removal programs such as AVG Anti-virus, Norton, McAfee or Spybot S & D cannot remove it, as you may have already found out.

Free specialised Smitfraud removal tool is here (SmitfraudFix)
http://siri.urz.free.fr/Fix/SmitfraudFix_En.php

After running SmitfraudFix, to clean-up any remaining infection traces, scan for trojans,
and spyware and remove (free online scan, no downloaded program) with Ewido Online Scanner ( now known as AVG Anti-Spyware). This is NOT the same as AVG Anti-Virus. Press "Online Scan" on the right.

Good luck.
