Windows update and AVG removal
I've run into several PCs that have AVG installed on them and after the Windows update, it can't be removed. I tried downloading the removal utility from AVG's site and it doesn't work either. I did find a removal utility made by avast that will remove AVG. I assume this was created in order to install Avast in place of AVG, not sure. I can't find it right now.
But what I did find out about this particular PC I'm working on today is that the Windows update and the user caused the problem. Here's how it works.
When the system was originally installed, the user did not use an email and Microsoft account to setup the PC. They didn't even use a password. When the recent Windows Update, I believe it was the Creative update, Windows asks again if you want to setup a Microsoft account. This time the user used an email address. After the update, the desktop appears the same, but we can't remove AVG. Even worse, AVG took over the firewall, I believe it was a 30 day trial of Internet Security, and blocked access to name servers. The PC was effectively locked out from the internet. We couldn't do anything about the firewall. The windows control panel access to the firewall services were locked out stating that we had to use AVG to make adjustments. Trying to remove AVG just didn't work with any of the recommendations I could find on the internet.
I finally into windows > Settings > Accounts and selected sign-in with a local account reverting to the original name that was already used with the same password they had before and I was able to remove AVG using the Control panel Programs and Features. Everything is now back to normal.
