I had a message "Avg is out of date", I tried to update but everytime was an error, so I decided to uninstall. But I can't do that either. Everytime I try to unistall there is an error. " 0xE001F946: Verification of digital signature fail." I searched about it and I found about avg remover tool that DIDN'T work AGAIN. I tried also to delete the avg documents but an ERROR appeared AGAIN: you need a permission to perform this action. I want to uninstall asap. SOS
