My PC is very slow when the internal protection scan is operating
You can set your protection level to 'Normal' instead of high.
when Windows starts. I've already disabled VRDB but that didn't help. When the scan stops after a view minutes I can normaly open folders without seconds delay.
You can't avoid that the resisdents start. Their not 'scanning', just 'openning'.
You can disable the providers you do not use.
I don't see a option to disable 'autoscan' in the 'Standard Shield' section (AVG has that option and it was also very slow when enabled).
If I understood you, there isn't such this option...
Are you talking about boot time scanning?
