No need to jump to AVIRA right away because of this alone. I’ll talk to avast! guys about it. I understand the reason why one would want to have such option. If you’re doing a full system scan and you have to do something on PC without having it all bogged down because of the scan and you don’t want to cancel the scan either, PAUSE was a great option for that.

EDIT:
While I was at it, I also requested option to change scan priority during the on-demand scan. I guess some people would find it useful (me included sometimes).
