AVG 8 - Invalid Update Control CTF File

I'm using Windows Vista 64-bit, so the location of the *.ctf files is different from that mentioned by others.

1. Go to “C:\ProgramData\avg8\update\download” directory.
2. Deleted all *.ctf files.
3. Launch update.

Note: you've got to choose "show the hidden folders and files" to see this path.
