I'm not the one, who infected your computer.

You're the very first one, who resist to uninstall AVG.

Combofix is a very crucial tool in malware removal and it has to be run.

I stopped recommending AVG long time ago and AVG conflicting with running Combofix is the latest reason, why I don't recommend AVG anymore.

I gave you options what to do. Contact AVG, or switch to some other security program.

The decision is yours and I'm not going to go back and forth with you over something what has to be done, if you want to clean your computer.
