I recently downloaded pivot animator for my PC, and it installed Avast on my computer without my consent. I saw a post that said Avast became Adware, but for some odd reason, the copy I got did not seem like adware. I haven’t been getting anything that seemed like ads. the only thing I got was a pop-up that said Avast needed to restart my computer, and nothing else.. I dont know if my Copy is a pirated version with viruses injected into it or I got a legitimate copy of Avast and it doesnt seem to be adware.
You possibly got a cracked for premium or just edited out ads version. If you are able to 100% determine that it is not a virus, then I would keep it. Run a scan with HitmanPro and Malwarebytes Free.
