"You have AdBlock enabled"

Hi,
I keep getting a message saying you have AdBlock software enabled where the advertisements normally go...

This is a brand new PC, i don't have any advertisement blocking software on here. The only things i have installed are:
AVG
FireFox
RsBot
Sony Vegas
PeerGuardian
Pinnacle Studio 11.1
AMCap
uTorrent

I just really don't want a ban for something which is a bug/i can't find the source of.

 

Run a research on your computer to see if AdBlock is installed on your computer or look on FireFox if it's on there.

 

EDIT:
Fixed, PeerGuardian had block ads on.
