That's tempting...

I've already uninstalled Malwarebytes Premium, it slowed down office applications start up about 3-4 seconds, despite that I've just renewed the "grandfathered" 3 PC license.

Vipre is starting to get on my nerves, maybe I'll try WD with PUA enabled. I just dislike how all of these third-party protection take over my system and prevent stopping services, deleting folders after uninstalling. Windows already doing that, don't need a company from god knows where to do the same...
