What is the difference between dynamic, basic, medium, and fast scan settings?

Ronald,
Dynamic: AVG Free automatically adjusts the scan speed.
Basic: The scan takes longer, but doesn't use as many resources.
Medium: >>>>>>>>
Fast: The scan runs at maximum performance, and you will see a performance decrease.

so I have avg antivirus full version 3pcs | 1 year

so is it best to put it in Dynamic mode or leave it off?

Hi Robert,
It depends on your preferences, but dynamic should work for most cases.
Thanks
