I suggest you do a clean reinstall:
- Download the latest version of avast, 7.0.1426 http://files.avast.com/iavs5x/avast_free_antivirus_setup.exe and save it to your HDD, somewhere you can find it again (if you didn't save your last download). Use that when you reinstall.

- Download the avast! Uninstall Utility, aswClear.exe find it here and save it to your HDD (it has uninstall tools for 5.x, 6.0.x and 7.0.x).

• 1. Now uninstall avast! (using add remove programs, if you can't do that start from the next step), reboot.
• 2. run the avast! Uninstall Utility from safe mode, first for 6.x if previously installed and then for 7.0, once complete reboot into normal mode.
• 3. install the latest version, reboot.

The above instructions presume you are using avast free.
