Agent.exe error, can't open Firefox / IE / or outlook

Here is the challenge Im having:
I'm running Windows XP Professional Edition <>  on my PC.
All of the sudden last night I can no longer connect to the internet; browser will not even open. (Firefox or Explorer) Microsoft outlook opens and then shuts down.
I am sending this from my laptop connected through my wireless router in my home.
I keep getting:
agent.exe - Application Error <
The instruction at "0x7c910f29" referenced memory at "0x00000001".
The memory could not be "read".
Click on OK to terminate.
Originally I just clicked the X in the top right hand corner. It kept coming back. I am running eset  version 3.0.621.0 and stopzilla.
Everything else seems to work fine, but I cannot get on line at all.
Please let me know a solution and any suggestions asap.
