Have you rebooted as suggested in the second image and tried again ?

If you have and that didn't work, try a repair of avast. Add Remove programs, select 'avast! Anti-Virus,' click the Change/Remove button and scroll down to Repair, click next and follow. You may need to reboot after the repair.

If that doesn't work you are looking at doing a clean reinstall:
- Download the latest version of avast AIS, 5.1.864 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, aswClear5.exe find it here (http://www.avast.com/uninstall-utility) and save it to your HDD.

• 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, for avast 5 AIS, once complete reboot into normal mode.
• 3. install the latest version, reboot.

It helps if your signature actually says what avast version you are using.
