Windows 7 Freezes after 30-60 minutes and freezes on Shutting Down Screen

Just as the title says I downloaded Avast and now 30 - 60 Minutes after I start my computer up it will freeze. I can still move my cursor, but everything else is frozen. Also when I try and shut down manually before it would freeze it gets to the “Shutting Down” Screen and just hangs there and I am forced to hold the power button and shut down manually.

I have since uninstalled Avast and now the problem is gone.

Just curious if there is a fix for this since I did spend the 20$ for a year subscription, or am I just out the cash.

Thanks!

A test for you…try to install and during the installer choose “Custom” & do not install NG in TOOLS section.
I only install the Avast “shields” but perhaps you want some of the other Tools, etc.
You can do a search on the Forum on NG but it definitely has an impact on machines.
It basically is a VM environment for pre-scanning items before they are on the real PC environment.

There are many that say it just does for “awhile” until it settles…for me I’ve had one PC is locked down like yours.
You can always re-install later in Programs>Avast with the CHANGE function.

P.S. Before you do the install run Avastclear to make sure old install is 100% gone.
