These leftovers sometimes can interfere with other security applications on some systems.
I am just a home user, not a computer expert.īut I have found over the years that many AVs leave behind traces/remnants/leftovers. As for files and folders, I can understand that it might leave a folder named Kaspersky with nothing on it, or a couple of log files (if you didn't opt them out) but they are practically harmless and won't cause any issues on your system.
KASPERSKY UNINSTALL TOOL MAC DRIVERS
If a standard uninstall actually leave drivers behind, then the uninstall didn't go well. I've been a Kaspersky user for many years (5+) and I uninstalled the product a bunch of time (OS upgrade, software upgrade, etc.) and not a single time I had to use their uninstaller. This way, if you reinstall a Kaspersky product, it'll automatically activate itself taking the information stored on the system if you still have a valid licence for the product.
The only thing that it'll keep on it by default (unless you opt it out) is the Licence Information. If you have a good installation, that isn't damaged or corrupt, the standard uninstall via the Control Panel will remove any traces from Kaspersky on your system. This isn't supposed to happen to be honest. In order to make sure everything is gone and avoid any issue later on, you have to use antivirus vendor uninstall tool to fully uninstall what's left behind. Well, uninstall antivirus/internet security from program/feature will left tons of stuff behind such as drivers,files,and some cache folders.
