Kaspersky makes it super easy to uninstall its application if you are not impressed. All you need to do is:
Open Kaspersky Internet Security.
Tap Settings > Settings > Uninstall the app.
On the Uninstall Kaspersky Internet Security screen, tap Next.
If prompted, enter the app secret code (the app requests the secret code if the Uninstallation protection checkbox is selected in the Anti-Theft settings).
Confirm uninstallation of Kaspersky.
Done!
