I have an XP SP3 machine that I just installed Avast Pro on, and scheduled a boot time scan. The machine starts booting, and goes to a blue Microsoft Windwos XP screen where it would normally tell you it's going to scan, but it just hangs there. I tried rebooting, and selecting last known good, but same thing happens. I can't even boot in safe mode.
If I boot from a cd, and scan for viruses, none are found. Is there a registry hack to tell the OS to NOT scan at boot?
