Assertion Failed error message at login

I thought I had fixed this by re-installing Avast, and it did work for a while, but it is back again.
What does it mean? I am using Windows 7.

I may have partially “fixed” it again by making my wife’s account administrative. Avast does run if I do that, but I am told that it is not a good idea. Also, this does not fix the guest account. Making that administrative is really a bad idea.

I copied some of the error message:

Microsoft Visual C++ Runtime Library
Assertion failed!
Program:C:\Program Files\AVAST Software\AvastUI.exe
File: .\CrashHandler.cpp
Line: 43

This topic has appeared in this forum before. One was June 24, 2012. I did not see a resolution to it.
Any chance it will be fixed in the next release of Avast?

I answered your other C++ topic, not sure if the two are related, presumably so.
