AVG8 Free Update Failed: Invalid CTF File!

When i’m try to update my AVG8 Free, I got error message: Invalid Update Control CTF File

Even if I tried to update again, I still got the error message, so I tried to search Google and found the solution from here:

The Solution:

  1. Go to C:Documents and SettingsAll UsersApplication Dataavg8updatedownload or search *.ctf from the start menu > search
  2. Delete avginfoavi.ctf and avginfowin.ctf
  3. Try to update again, it should be OK

That’s all.
