Did you report it?
I am very disturbed to discover that on two occasions AVG have entered my Antivirus Free application without permission and have made alterations to it - interrupting the operation of the programme and its protection.
Not only is this without any reference to myself, but it is in contravention of the application's own settings. Antivirus Free has a user-configurable Update Manager. I intentionally keep the automatic operation switched off, precisely in order to retain control of the application and updates added. Yet AVG bypass this when it suits them.
The whole reason we install antivirus applications is to prevent unauthorised interference with our computers. Why does this manufacturer assume the right to do the same ?
