The patch that was previously for 6.0.1203 is/should be incorporated into the latest avast release, 6.0.1289.

So all I can suggest that you do a clean reinstall of avast IS:

  • Download the latest version of avast, 6.0.1289 http://files.avast.com/iavs5x/setup_ais.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 both 5.x and 6.0.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 5.x if previously installed and then for 6.0, once complete reboot into normal mode.- 3. install the latest version, reboot.

If that doesn’t resolve it, as the patch is incorporated into the latest release, there is something else in the mix.
