avast! has been updated to build 1123, then it advised me to update Anti-Theft to build 1900.
The update was successful, but when i've tried to enter into Anti-Theft settings, i've got a message that the app isn't installed. I've rebooted my phone. Now i can enter into Anti-Theft settings, but,firstly, i see avast! Anti-Theft application in the apps list and,secondly,i can kill the app through the list of running programs(LOCK message does nothing).
Using CyanogenMod 7.1.0, LG P500.
The problem was reproduced with the similar P500.
