packed.generic.295 security message

Hi

 

I ma having diffucuility with Norton Internet Security 2009.

 

When using the internet (via Firefox) I am getting a constant popup from Norton informing me that "a security threat from packed.generic.295" has been blocked and that no further action is required, than I get the all threats have been resolved popup. This is happeining every 30 seconds. I have run Malaware and turned off system restore, run a live update from Norton and a full system scan...both are comming back clear, however teh popup keeps happening and is seriously worring me and slowing my system.

 

The threat blocker is not giving me the option to report to Norton and I am at a loss as to what to do.

 

Any suggestions

 

Sory for the lack of technical details but I am posting from work.
