Invalid Update Control CTF File error during AVG update

I was trying to update AVG antivirus definitions. During update I started getting errors saying Invalid Update Control CTF File. Because of this error I could not update AVG.

The solution for this is very simple. I have deleted the .ctf files from AVG folder and could able to update normally.

You need to navigate to following folder:
C:\Documents and Settings\All Users\Application Data\Avg8\update\download\
You will find at least two .ctf files in this folder. You can rename those OR can remove. After rename/remove, try to update the AVG definitions again. It should work properly.

Happy browsing…
