Last week when I try to run the update my AVG 8.0 free edition and getting the error message of “Invalid update control CTF file”.

So try I’m to google it for the solution and finally get it. The step to solve it is pretty simple, you just need to delete the previous download *.ctf file and let the update engine to start all over again.

The step as below:

1. Open My Computer.

2. Goto C:Documents and SettingsAll UsersApplication DataAvg8updatedownload.

3. Delete all file which end with .ctf such as avginfowin.ctf, avginfoavi.ctf, avginfo.gen.ctf etc.

4. Done! Try to update again the antivirus

* Remember not to delete the file end with .bin, because those are the ones that where complied on previous updates
