Invalid Update Control CTF File – AVG 8
Had a client that had this issue. You simply need to remove the
CTF temp files in C:\Documents and Settings\All Users\Application Data\Avg8\update\download
Only remove the 2 files that end with .ctf.
Note: The Application Data folder is hidden by default. Use the Start, Run dialog and press {ENTER} to open the folder.
Windows Vista users: Delete the .CTF files from the following folder:
C:\ProgramData\avg8\update\download
