Dear Admin,

I installed your antivirus and it was alright until a recent update on Avast which made none of my usual service apps such as Grab, Dahmakan, Foodpanda etc allow payments via mobile. It is giving me much hassle since I have to log on a laptop instead of making payments on my phone. Please assist URGENTLY.

Hi, we have no idea how our app could cause this.
Could you specify what the Avast Mobile Security app exactly says, what do the other apps say (you can post screenshots)?
What happens when you uninstall our app? Does the problem persist?
