Thanks for the info. I had searched for mIRC on my computer and found nothing. I have also ran my computer through serveral virus scanners...I am using a few more that were in the link you provided as I am typing this.
I figured it was a Trojan virus, but I was curious if anyone would know which one would cause it on bootup of Windows.
If there are any other ideas on what would cause this, I would appreciate them as well.
