avast Internet Security crashed my system

I’ll get the latest version number, etc when I get home.

After downloading latest updates (there were no other changes during that computer session except the avast updates), I rebooted as requested – and my system froze while booting – after the Windows logo screen.

I had to “restore from last good configuration” to get the computer to boot successfully, but…

  1. avast will often freeze when turning on the Firewall, and randomly – and frequently – at other times.

  2. My USB drive cannot be turned on to boot up. I have to turn it off during bootup and turn it on afterwards. Never had to do that before that avast reboot.

I suggest an installation from scratch:

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. Uninstall avast from Control Panel (if possible). If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after that.
  4. Run the avast! Uninstall Utility saved on 1. If, for any reason, you can’t run it, try booting in Safe Mode and doing it from there. Anyway, boot after you’ve run it.
  5. Install avast! using the setup saved on 2. Boot.
  6. Register your free copy or add the license key for Pro.
  7. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

If it does not work, you can try disabling Behavior Shield or even not installing it (custom installation).
Please, post back the results.

i uninstalled and reinstalled avast per your instructions - some problems went away - such as the freeze ups - and the USB hard drive would automatically load at bootup - however - another program wouldn’t load - even after reinstalling it - and the computer became ponderous

all the problems went away when I uninstalled avast again - and that’s the way it’s gonna stay - I wasted money on avast

Did you try uninstalling the behavior shield as Tech suggested ?

Yes. Behavior Shield didn’t seem to have an effect the problems.
