Interesting Problem. I am running Kaspersky on a Google Nexus 3 OS 4.2.1. I am experiencing the same problems of KSM AP stoped working that I have seen on several other forum posts. I believe KSM was on 9.30? I tried updating KSM, but could not get the auto-update to work. Note: KSM would stop working before I could get to the KSM PIN Screen. Next attempt. Unistall KSM. I began trying to unistall KSM from the phone. Something "odd" happened. It logged the phone off. To the best of my knowledge, It reset to my phones PIN screen. Now my phone's PIN has been changed. and I am essentially locked out of my phone. I have submitted a ticket to Kaspersky and my first attempt at over the phone help was un successful. Any suggestions as I am now locked out of my phone atm. Ken.
