Hello! I keep getting a message from Avast! saying that it has blocked Win32:Small-NNE [Trj] and I was wondering where this virus is coming from and how can I keep it from popping up. Is it coming from a specific website that I'm visiting? Why does it pop up immediately when I open up Firefox? I know Avast! is blocking it but it's making me a bit nervous.
By the way, I did a full scan with Avast!, MalwareBytes, and Spybot Search and Destroy and everything came up clean.
