Today I got a kind of a BSOD after having installed defs with pre-release enabled, having done an in-depth scan, and rebooted. I had to do an hard reboot. This is maybe related to: https://www.wilderssecurity.com/showpost.php?p=1768461&postcount=13 Maybe it could be a sudden conflict with an other start-up program. I am on XP-home SP3, Dutch, IE6. EAV 126.96.36.199 English. I have put back a backup-image (Acronis TI 9-0-3.854 running from its bootable CD) from 10-10-2010. I was lucky to be able to make a backup of my emails with Express Assist. I have not yet put that backup back. I have now pre-release disabled. I'll start slowly to update things step by step (like EAV defs and the MS-updates again from this week) to see how it is going. I don't have much time for testing.
