I have had numerous screen hangs but after about 30 seconds the mouse restores. But recently scanning with PcTools Threatfire the threatfire screen hangs but rest of screen seems to respond. Couldn’t use Task Manager or shutdown. Drive activity continued like something was going on. Threatfie screen in staus bar shows Not Responding. Waited 30 minutes the shutdown by holding power button until powered down.

Using eBoostr beta latest,  PcTools Threatfire 4.0.0.10.  Drive activity was shown by Hddled program.

Have had no blue screen of death at all.

Most times any poblem has bee whole screen freezes for about 30 seconds like explorer has to catch up then everyting contiues.
