I don't know, my personal windows install which I use for photoshop, lightroom, and the occasional game also has similar issues, and it only has the included windows defender. I've noticed on many computers that whenever there are a bunch of files in a directory, the explorer grinds to a halt.

At work we use clownstrike for our driving-around-with-the-handbrake-on needs, which I have installed on both Linux and Windows, and the former flies while the latter lags all the time (I dual boot, so it's the same exact hardware). Doing something which is fully equivalent, like installing an IntelliJ update takes around a minute on Linux and many more on Windows.

The fan also comes on much more often on Windows than Linux, even though most of my job is done on remote servers via SSH. Under Linux I only hear the fan when I compile something. This morning I booted windows and the fan was running constantly while I was just catching up with a few mails in outlook.
