I'm on 2.90 and can't find any weird processes running. I'll hold off on 2.91 until they've explained what happened.

that feels like a pretty week standard for knowing if your machine is infected. I will look for a virus scanner myself, and seriously think about reinstalling if it finds anything

Yeah I know, it is the lowest effort. But I'm not running it on my main system. Worst case I'll have to reinstall (unless it messes with the hardware, firmware changes for example).

I believe only manual downloads of 2.90 were infected, the in-app update should have been clean.
