The issue is program update setting definitions updates to auto.
I am aware of HDD problem, it will be fixed either when current HDD will die, or when PIO slowness will become annoying enough. I have good backups, so data loss because of sudden HDD failure is not considered to be a problem.
Program update reseting definitions updates to auto, has happened also on fresh installations (first program update). (tested on winxp and windows 7 on 3 different computers) On those (mostly faster) systems, definitions autoupdate is not that crippling to performance, but is still annoying, so this in not likely to be problem with remains of old version in this computer.
Generally avast antivirus works fine and program updates are not that often, but when there is a program update, it also involves need to go through settings to undo damage it did. I was just looking for means of avoiding this extra chore.
