Howdy,
I've experienced this before with a different anti-virus and was hoping Avast would be different. I've run the Home version for a few weeks now with no problems and I upgraded yesterday to the Pro version. Avast Pro is doing the same thing Panda used to do. I get to my login screen and it won't let me get any further the background is blue and just sits there. I then have to hold the power button in to turn off the PC so I can log in with my backup profile. I stopped Xfire from auto starting and I'm able to get in to my profile through my backup profile. I don't want to do this, I would rather have xfire run at start up.
What causes this is Avast must be attempting to scan something with Xfire which is set to auto start. The same thing occurred with Panda, however I was able to turn off the feature that was casing it TruPrevent.
Panda Anti-Virus has a thing called TruPrevent where it monitors what is going on and basically alerts you if it thinks it has found a virus. It is not quite real time protection because it does some type of checking. Excerpt from Wikipedia: Truprevent Technologies offers generic protection against many of the techniques most commonly used by new malware, and policies and rules are developed based on the new vulnerabilities that appear every day.
How do I turn this off?
