As the biggest selling point is noted in any case that the program brings in the background no noticeable performance degradation with what my other antivirus software (eg Norton) is ever noticed negatively. Even on the phone, I can not affect the battery time to confirm (Galaxy Note 4).
For me, not true, but certainly interesting for families with children is the child lock. On the phone, the program can also prevent unwanted app purchases here!
Overall, I am very happy with Kaspersky, and hope that I will never really need it :-)
