The different ratings at this point it can be concluded that the use of this virus scanner can not expect consistent results.
Because of the frequent activities of the software that do not appear in the other, the batteries of laptops are faster yet.
The virus scanner itself is in itself good, so even a star. The company Kaspersky is strongly encouraged to streamline this product and to restrict themselves to the virus and Adwareerkennung.
One tip: because the software is very deeply incorporated in the BS to remove unbdingt the use of Kaspersky Removal Tool kavremover.
Addendum: errors on all devices. On my last laptop Kaspersky prevents access to Google and Google classifies as a security risk. One may go along since the content, but this is not at all disconnected.
