Yes, I know, and that was why I was a little bit surprised to find the comment that I quoted in the FAQ-part of the CAVS-forum. (Written by Ewen)
I run Avast, but ran into a problem with a Trojan it couldn’t remove. Just as a test, I uninstalled Avast and installed CAVS, and it took care of it at once ( (S) ). I’m waiting unpatiently for the next update, but even though it saved me this time, I’m not ready to make the switch yet - Avast has served me perfectly for several years. So - I uninstalled CAVS and installed Avast again.
BUT - if (according to the quote) it is possible to have one on-demand scanner and on that runs on-access, I would reinstall CAVS immediately…
It’s the resident protection, what you can’t have two of them. But you can have as many AV installed as you want, as long as no more than one of them has resident protection running. Not sure about the details about CAVS and Avast though, so I can’t tell you how to opt the resident protection out, maybe someone else will or you’ll figure out yourself.

I’m pretty sure you don’t have to, but maybe someone more knowledgeable will tell you better. Or you could just go ahead and if you don’t experience any conflicts then all’s OK.
I use two AV myself. One is active (on-access), the other is not (on-demand only). I do not disable either AV to perform scans.
If you find that you’re bogging down having both on while doing the on-demand scan, then turn the other off. However, I wouldn’t anticipate there to be any problems.
