Error “Invalid Update Control CTF File” When Updating AVG Anti-Virus 8.0 November 5, 2008

You need to rename/remove the CTF temp files in C:\Documents and Settings\All Users\Application Data\Avg8\update\download…. Dont delete all the .bin files in there unless you want to re-run all updates since your original installation (reinstallation seems to cause a problem in IEs Link Scanner which causes IE to Crash). Only rename/remove the avginfo files that end with .ctf.

There were two .CTF files (avginfoavi.ctf and avginfowin.ctf) in that folder, and deleting them fixed the problem indeed.

Note: The Application Data folder is hidden by default. You need to enable Windows Explorer to show hidden files in order to view the Application Data folder. Alternately, type the above folder path in the Start, Run dialog and press {ENTER} to launch the folder.

Windows Vista users: Delete the .CTF files from the following folder:
