If anyone is receiving the message, "Invalid update control CTF file", there's a solution.

I came across the error myself - But I did my research and found the following things on the AVG Support Site.

Double-click the My computer icon on your desktop (or open Start -> My Computer)
Navigate to the following folder:

Windows XP / 2000:
C:\Documents and Settings\All Users\Application Data\avg8\update\download *

Windows Vista:
C:\ProgramData\avg8\update\download *

Find the avginfoavi.ctf and avginfowin.ctf files and delete them
Restart your computer.

Note: If you cannot find the folder ''Application Data'', You need to un-hide all folders / files.

That should cure it. It worked for me :)
