Something is corrupting your update?
Any Internet filter? Other security application? Hard disk errors?
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.
