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. This has in the past resolved this out of sync issue between reported and actual virus definitions version.
If that doesn’t work - Try a clean reinstall:
Download the latest version of avast, 5.0.507 http://www.avast.com/free-antivirus-download 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 and save it to your HDD (it has uninstall tools for both 4.8 and 5.0).
Now uninstall (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 4.8 if previously installed and then for 5.0, once complete reboot into normal mode.- 3. install the latest version, reboot.
Looks like 4.8 didn’t uninstall properly. It still showed up in add/remove programs. But I couldn’t remove it there.
I used the clear utility to remove 4.8 completely in safe mode, restarted, then 5 was no longer running, so I did a repair under add/remove programs for that, and then restarted the avast service.
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.
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.
Install avast! using the setup saved on 2. Boot.

The internet Mail shield doesn’t require that the email client is open for it to start, unlike the MS Outlook plug-in in avast 4.8 (waiting for sub-system message).
DavidR, I cannot thank you enough. I spent all day today trying to get my Avast to work again. I had the same initial problem (the Mail Shield could not be turned on and the Fix It Now button did nothing). I followed your instructions to the letter, and voila…fixed!! I’m so happy :)))))))
P.S. I didn’t know how to start my computer in safe mode, so I had to clear that hurdle.
i have windows 7 64-bit and outlook 2010 and Avast 5.0.594. When avast enabled cannot access to POP3 server. when shields are disabled outlook is working. outlook was installed after avast.
