Error “Invalid Update Control CTF File” When Updating AVG Anti-Virus 8.0
When updating AVG today, I received the error "Invalid Update Control CTF File". After searching the AVG support forum, I found a couple of easy solutions which can resolve the error.
Note: (Nov 03, 2009): AVG Team is working on this issue and should fix this update issue soon. No user action is needed. The following methods worked for some users, though.
Method 1
1. Double-click the AVG icon in the Notification area.
2. Click the Tools menu and click Advanced Settings…
3. Navigate to the Manage option in the Update branch.
(The Manage option is included in AVG version 8.0.233 and higher.)
4. Click the Delete temporary update files button.
5. Click Yes to confirm removal.
See if you’re now able to update AVG.
Note: The above button deletes all the temporary files, downloaded .BIN and .CTF files which were created by AVG. Whereas the Vbscript file included under "Method 2" deletes only the .CTF files.
Method 2
From AVG forum:
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:
C:\ProgramData\avg8\update\download
Script to automate the task
I’ve scripted the above so that it can help if you want to run the task in multiple PCs. Download del_avg_ctf.zip and save to Desktop. Unzip the file and run the script del_avg_ctf.vbs. The AVG Update .CTF files should be deleted automatically. The script runs fine in Windows XP and Windows Vista systems.
