@ 01012k7,
Support for v.4.0 will be ending very shortly and you will no longer be getting virus updates. Therefore I strongly suggest that you uninstall Avast and do a clean install. This way you will continue to get the virus updates and have AV protection.
How to uninstall and do a clean install of Avast:
1. Save a copy of Avast and save it to your HDD.
2. Download the Avast Uninstall Utility http://files.avast.com/files/eng/aswclear6.exe and save it to your HDD.
3. Disconnect from the Internet at this time.
4. Go to Control Panel and uninstall Avast through Add/Remove Programs if possible and reboot.
5. If Step 4 fails, boot into Safe Mode (hit F8 repeatedly) and run the Avast Uninstall Tool. Uninstall ALL previous versions and products you had on this machine at this time.
6. Reboot.
7. Install the newest version of Avast and reboot.
8. Get Internet access and register your copy or add the license key for Free, Pro, or AIS.
9. Update the Avast definitions.
Now that you have your license, please let me know if you have general questions, or contact sedina@avast.com regarding license issues. Thank you.
