My Internet computer is on from around 8 AM to 11 PM and I have never had any problems either. I also am very careful about what goes in this computer and what I view on line.
When working with my music computer I like to keep everything off that can run in the background, including my Ethernet card, Defender, anti-malwarebytes, and cCleaner. That way nothing can interfere with my recordings.
I know this is an old habit that I acquired back in the much slower CPU days but it is one that has always worked for me. So if it ain't broke I ain't changing it. YMMV
For those who don't want Alexa listening to your conversations they're making a male version, it doesn't listen to anything!
64 bit Win 10 Pro, the latest BiaB and RB, Roland Octa-Capture audio interface, a ton of software and some hardware.
