hope this helps
it could be fake. or a scam to attempt to get you to purchase a rogue malware removal product. The balloon about "You computer is infected", is always false, phony and fradulant. The actual trojan that has caused your problem is no doubt one of the hundreds (now in the thousands)of varients of what is commonly called "Zlob".
But your computer is indeed infected. This infection is called Smitfraud and it will give you phony scam virus warnings( and often redirect you to a site selling a bogus anti virus product), trying to sell you junk such asPest Capture, Pest Trap, Virus Burst, Spyware Quake and other non working anti virus apps.
