I think the word "piracy" is overused and crates overreaction, and this is one of those cases. Try a google search, myths like these have been debunked for ages now: I'll get you started
http://www.freefixer.com/library/file/AcWebBrowser.exe-213827/There are proven ways to keep your PC safe: start by purchasing a class-A malware/anti-virus and \reputation-protection' software subscription with live always-on scanning/monitoring and you're pretty much good to go. Follow proven safety tips about emails, websites and more and you'll be even safer.
Purchase a proven hardware-based firewall with current paid-for subscriptions to interrupt outsiders from going through your ISP and you're golden.
In AutoCAD, install HELP files locally, not the default web-access versions, log-out of A360 (or don't even install it) and do the same with the Autodesk Application Manager, and remove AutoCAD's Content Browser if not used at all too.
Skip these "sniffing through Windows running background apps" as a method of protecting yourself: that is a false safety, not a true one, and you'll only worry about irrelevant threats instead of actually protecting yourself from real threats.
Good luck.
