BleepingComputer.com: Windows Error

I was browsing MYSPACE when my screen went black n' pushed n held in the start botton on the computer to shut it off n' then restarted it. A message appeared something along the lines of "windows has recovered from a serious problem/erroe (i am not completely sure which word was used) would you like to send a report"
I sent the report and was taken to a window that said this:

Problem caused by Authentium Security Firewall/Antivirus driver (grtdimon.sys)

This problem was caused by Authentium Security Firewall/Antivirus driver (grtdimon.sys). Authentium Security Firewall/Antivirus driver (grtdimon.sys) is distributed by many companies.

Hello,

It sounds as if your security suite failed whle you were browsing, as firewall and antivirus are embedded into the system, when or if one fails it will usually crash the system.
I would run some free online AV programs, just to make sure nothing got in when the system crashed.

Which security software do you have? (Anti virus/Firewal?)
