disable avast but not uninstall it

[antivirer]

hello

Avastsvc.exe consumes 30,000K mem usage as task manager shows and this is alot

is there a way to permanently disable Avast from loading/working, but not uninstall it?

please note I don't want to do this procedure each time I restart Windows, ie I don't want Avast to load each time Windows start and each time to disable it from its menu

I know that it is supposed to protect etc, but I don't use antivirus at all most of the time

thanks

avast is not intended to run as on-demand only.
Besides if you disable it, you'll be without an antivirus.
Disable is not enough to install another one. If avast is not what you're looking for, uninstall and try some other, but keep an antivirus on.
Oh, maybe buy some RAM

You can remove the startup entry (avastui.exe) and disable the services. But the low level drivers will be loading. You can't install another antivirus.

@ the OP: you call 30.000 KB a lot how much RAM have you got? anyway there's something wrong if it takes that much when idle...but on "normal" systems, this should have no impact. Something wrong because it doesn't take that much here: svc takes about 10.000 KB here and UI takes 5.000

When you compare what is an essential application with others using memory avast isn't a really big deal on my system. Not to mention RAM is there to be used, if 30MB concerns you then increasing RAM will help overall system performance.
