Removed Avast on my newer Intel I7 based laptop, and did receive the update right after restart after Defender was activated, have not tried reinstalling Avast Free yet, but I might, as rest of the systems using Avast Free, Desktop did it manually with the windows catalog update way
don't know why couldn't get it from WIndows update with Avast installed, reg key was there, so makes no sense, Malwarebytes supposedly was up to date the program said
