Symptoms:
System will freeze, including numlock and caps lock on keyboard.

A random message pops up warning of an IE script that is consuming too many resources, IE is not running when this happens.

Started with a warning about Univ.script/99a from McAfee, version 11.2 on my wife's computer, spread to our laptop and my desktop.

I have brute force recovered (format/reload) the laptop and my wife's system. I have not done that to my desktop, I am hoping to find the cause before it repeats.

All three systems are running XP Pro, SP2 with all of the updates.

My wife's system is an 8240, mine is an 8250 and our laptop is an Inspiron 8600.

Interestingly, my kid's sytem, an E-Machines, and my son's laptop, a compaq, were not affected, could be that they were not used during this time.
