- With a resident on-access antivirus like avast, the need for frequent on-demand scans is much depreciated. For the most part the on-demand scan is going to be scanning files that would be otherwise be dormant or inert. If they were active files then the on-access file system shield would be scanning them before being created, modified, opened or executed.
I have avast set to do a scheduled weekly Quick scan, set at a time and day that I know the computer will be on. If for some reason my system wasn’t on, no big deal I will catch up on the next scheduled scan.
As for if you have set a weekday Quick scan and it falls on the same date as a monthly Full scan, they would both be done as there is no way to have any limiting factor (not GUI option) on running what you have scheduled.
The more frequent weekday scans you do the more chance you have of the Quick and Full scans being scheduled on the same day.
I used to schedule a monthly (1st day) Full scan, but in all honesty, it is going to find little of importance as that serious areas/files are scanned by the Quick scan. Whilst I quickly (excuse pun) abandoned the monthly Full System scan, it never found anything, but then again I never expected it to.
