I'm using Win10 with Defender / Security Essentials.

I have a problem with WinSCP (thanks for an awesome program by the way), in that scrolling the Local browser in my Downloads folder, which naturally contains quite a few large archives and .exe installers, usually always freezes and lags for a few seconds repeatedly when scrolling down. Obviously this is because the on-access AV engine is scanning the files that the browsing window is showing.

I was just wondering, is this necessary? Is there perhaps something the program is doing that's causing this, that you might consider changing? I can't see an option for file previews or anything like that to turn off.

It's rather loading of icons from .exe files.

You can turn that off using hidden confirmation option Interface\LocalIconsByExt:
