His program broke my computer!

This program broke my computer! I installed it only hours ago and it crashed my computer. For the last 5 hours i have tried to fix the problem. But nothing works! Right after I installed this AVG protection I lost o access to ALL programs and files on my PC. I have tried installing the AVG remover tool but it does not run.
