Program update killed boot up

Got the shiny blue update now message, after update Avast needed to reboot, after reboot PC hung on login (waited 15 minutes) rebooted and still hung on login.
Used safemode to use System restore point, now i can login but avast is deadwood.

Will uninstall/Reinstall sort this issue out or do i need to take other action before reinstall?

Windows Vista Home Premium SP2 - 64Bit - Avast! Free Edition.

I suggest an installation from scratch (specially step 4):

  1. Download the latest version of avast! Uninstall Utility and save it.
  2. Download the latest avast! version and save it.
  3. (Optional) If you want, save your avast! settings for later restoration (Settings > Maintenance > Back up).
  4. 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.
  5. Run the avast! Uninstall Utility saved on 1 in Safe Mode. Boot after you’ve run it. Repeat this for any major avast! version you have ever installed/upgraded in your computer.
  6. Install avast! using the setup saved on 2. Boot.
  7. Register your free copy or add the license key for Pro. Or even upgrade your key from old versions.
  8. Check and post the results. If, for any reason, you did not solve, try doing the step 3 in Safe Mode anyway.

Thanks for swift reply :slight_smile:

I’ll edit this post after trying.

Could not uninstall via control panal, both normal and safe login gave following error

Error reading product data C:\Program Files\Alwil Software\Avast5\setup\past-setup_ais-557.vpx Setup cannot continue.

Follow Tech’s instructions.

If uninstall from Control Panel was unsucceful, apply avast! Uninstall Utility for all Avast! versions you have had installed in your comp. Start with v.7 and then v.6 and so on, with reboots for each of them.

My blacklist of dangerous seadogs be safely aboard.

Thanks for the help with sorting this issue :slight_smile:

Update:

Since this post i have followed instructions on removing/fresh installing and have now had my 3rd instance of ‘bootup hang’ following an update so i think ill try to find a link to v6.

I have used avast for several years with no issues before so this is not a QQ post, Just a heads up from an avast/vista user encountering a recurring issue.

  1. Download avast! Free Antivirus: http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe
  2. Follow instructions: http://www.avast.com/uninstall-utility
  3. Reinstall avast! with the downloaded installer from point 1.
  4. Reboot.

Exact same issue for me.

Tried clean install, same issue.
