Makes me wonder why installers themself don't do a proper cleanup in the first place. Pretty much EVERY antivirus that i've tried left bunch of crap behind after uninstallation. And nothing was ever like quarantine files. Always some useless garbage that has no meaning to stay there.
And some even leave active low level system drivers installed which then make absolute wreck once you install 1 or two security apps later. because every leaves some crap behind, its just accumulating and making more problems. I just don't get it.
I'll have to test their cleaner if it does anything this time, it did exactly nothing for v7 once it was uninstalled before the cleanup...
