Yikes! I guess someone had to have problems. (Why me?)
I installed 1035 from The 1027 GUI only to be greeted with a BSOD on restart. After trying Windows startup repair and a couple more reboots I uninstalled Avast completely. Then I downloaded the full version 1035, installed it from scratch, and got the same BSOD.
Undaunted, I uninstalled 1035 again, installed 1000,upgraded to 1035 from the 1000 GUI, and got the BSOD again.
Since I didn't save either of the intermediate updates, I'm back to ver 1000. FWIW, I'm running Win 7 Ultimate x64.
Any suggestions?
