Invalid Update Control CTF File in AVG 8.0

I was working on a customer’s computer yesterday and their AVG antivirus program didnt appear to be updating correctly. When I ran a manual update I received an error about an “invalid update control CTF file”. After some searching on the Internet I was able to find a solution. 

A fellow named Gary James that runs a blog called Strategy Online has actually created a program named AVG Mechanic to delete all the CTF files in the C:\Users\All Users\avg8\update\download directory and clear up this problem.

Visit Gary’s blog and download AVG Mechanic if you receive this message.
