I wanted to ask if somebody knows if I can change the scanning priority of the automatic virus scan which I started in the tasks panel in the enhanced user interface.
I want it to be set to low, so when avast runs this scan it doesn’t slow down the computer
The idea of having it set to high is so it can quickly deal with the scan (and any necessary action) and hand back to other programs on completion.
Rather than having to fight or wait for its share of the CPU pie with other programs set to LOW (most), which may mean slower scans (rather than quicker) and possibly leave you more vulnerable.
The idea may be good in some cases but mainly for the resident shield,not for the sheduled scan.And I really think that this option should be added in avast.Every program which supports sheduled tasks should allow priority change.That’s why i like avast.It can be configured anyway(or almost).
When I’m doing something else and avast starts scanning i have to stop avast in order to finish my job,and this can be avoided by adding such an option.
Thank you!
Neron, just send the session to Background. It can be done right clicking the skin (Home version) or in the Arquive menu of the Pro version. 
Anyway, won’t be that bad if we can check (set) the priority at the schedule dialog
As a matter of fact, in all Windows versions up to XP and Win2K3 server, the process priority settings have very little effect. So unless the process is really stuck in a tight loop, there’s almost no difference if the priority is say Normal or High.
This is mostly caused by the fact that priorities only influence the thread scheduler - and not I/O.
Under Windows Vista, this is going to change. There’ll be e.g. concept of “low priority I/O”, i.e. if a process (or thread) runs with a low priority level, the I/O requests it initiates will also have lower priority, making it easier for the system to distinguish between what needs to be done FAST (such as paging) and what can wait (such as background AV scanning or content indexing).

We know that changing the priority of ashserve.exe is not a good thing…
But, my wish was - and still is - have a low-priority schedule scan:
Vlk, can you confirm this is not possible (yet) and only on Vista and avast 5 we’ll be able to do that?
If we can ‘send a scannig to background’, why can’t we schedule one?
