I swiped these instructions from another forum member. It's caused by an error in the avast5.ini file. (at step 4)
1. Avast main GUI -> settings -> troubleshooting -> disable the self defense module and save settings (don't worry about the messages, accept).
2. search for the file "avast5.ini" (even if it is version 7 of avast); EDIT the file with notepad.
3. in "avast5.ini", look for the "[common]" section. There should be an entry named "ShowSetupOutro".
4. change the above entry "ShowSetupOutro" from 1 to 0 (zero).
5. save the file and reboot.
6. go back to avast main GUI -> settings -> troubleshooting -> enable the self defense module and save.
Thanks for the useful tip Charyb.
I had the same problem with a Windows XP SP3 computer. The nag screen had a checkbox for participating in the Community, which I unchecked but it returned after a reboot. I did it again once or twice and the checkbox disappeared but the nag screen continued. I then came here, found this thread, followed your advice how to edit the avast5.ini file and it stopped the nag screen, however... When I restarted my computer again it said my Web Shield was disabled. Looking at the Web Shield directly, it said it was running OK. Also when I attempted to tell it to fix it, the fix button was inactive. I found another fix button which was active and avast was apparently returned to normal. However checking my settings showed that the participation in Community checkbox had become checked (I unchecked it originally). So I'm not very confident that I have a stable install of avast7.
I will also mention that the avast7 upgrade on a W7 computer contributed to a total freezeup of that computer. So it appears that this version 7 upgrade is pretty buggy, causes problems, and may produce an unstable package. Maybe better to do as Hectic4409 suggests, uninstall the old version, then reinstall the new version clean(?). I'll definitely try that if there are any further quirks/problems.
In the meantime it looks like the avast backroom boyz need to burn a little more midnite oil!?
