"A recent attempt to attack your computer was blocked."

Ok so, I've been having a little problem recently involving this particular error message;

I get this message very regularly, however only when using an internet browser, particularly firefox. So my instant reaction was to disconnect from the internet since these attacks were all coming from .com addresses and this stopped the attacks. I then ran a full system scan using the new 2010 Norton Internet Security and it pulled up around 14 Tracking Cookies and 3 of; "Browser.Hijacker" I reconnected to the internet and opened firefox again but still I am recieving these messages.

My next plan of action was to try a different antivirus software which I know to be extremely good at removing viruses, but it firewall could never match Norton's. This pulled up over 130 Tracking Cookies, and a couple of other adware problems and removed them.

Guess what, same message!

Right now I am still having this problem and I am in need of help as I feel that eventually it will get through my firewall. Is this perhaps a code that my firefox has been bugged with to autorun it?

The message just popped up again ¬_¬

But any help would be of great use to me so pleas reply if you have a solution.

Thanks
