Avast Anti-theft problem in Kitkat 4.4.2

Avast Anti-theft was installed in my phone. After a factory reset, whenever I switch on the phone, sms is being sent to the numbers registered and balance is being deducted from my phone. I have tried getting rid of the problem by uninstalling and reinstalling Avast Anti theft as well as Avast Mobile Security, by removing the device from my Avast account device list, but in vain. Please help me get over the problem at the earliest.
