should it be on standard or high?im useing the home edition.can anyone help?
The Normal sensitivity is the best balance between security and performance.
Did you disable any other avast provider (that you think you do not need)?
ya the vrdb im useing vista home premium and i was told that the vrdb dont really work on vista
VRDB isn’t a provider, just an avast feature to restore (clean) some infected executable files.
If you set it to idle time in Vista, it will run automatically each 21 days, regardless the system is or not in idle mode.
so tech should i have it on when computer is idle or should i just leave it disabled?
Let it to be done when idle, it’s safer.
If it bores you while being generated (using resources), let it manual and do it once a month 
thank you tech
You’re welcome.
