A solution that worked for me:

Please kindly follow these steps to delete mentioned control files:

* Run the AVG Free user interface (double-click the AVG Free icon on your desktop).
* Open the Tools -> Advanced Settings… menu.
* Navigate to the Manage option in the Update branch.
* Press the Delete temporary update files button.
* Try to update AVG Free.

On a brand new computer with WindowsXP, a clean install of AVG 8.5 (4/28/2009) I get the “Invalid CTF file” message. I tried reinstalling, didn’t work. There are no .ctf or .bin files in the download folder of application data…
I downloaded today’s AVG definitions (a .bin file) and manually installed them successfully. This put a .ctf file in that download folder, but still when I ask it to update I get the same error message. Scanning with AVG and Malewarbytes did not turn up any infections…
What the heck do I do???

And what is told here: http://freeforum.avg.com/read.php?13,164852,164852,backpage=,sv=#REPLY –>> is perfectly correct . it changes ur dns servers[trojan].
may be reinstalling will do the trick.

I had the same problem with no CTF files found in C:\Documents and Settings\All Users\Application Data\Avg8\update\download.
After having tried everything, I finally found the answer on AVG site : http://freeforum.avg.com/read.php?13,164852,164852,backpage=,sv=#REPLY. This user explains how to get rid of Trojan that prevent to do correct AVG update.
And now all is fine for me.
