Error updating Free AVG (ver. 8.0) - Invalid update control CTF file

Free AVG is my favorite anti-virus/anti-spyware application. It's light, easy to configure, and best of all, free.

Recently, I noticed an exclamation point over the AVG icon in the system tray. (AVG ver 8.0.176. OS Windows Vista Home Premium, ver 6.0, build 6001), Opening the AVG User Interface (right-click the AVG icon in the system tray), I noticed the latest virus definition updates were marked as not being updated. I clicked the "Update Now" menu button, but received an error message when the application tried to update itself. The error read: "Invalid update control CTF file". I went to the AVG website, & found the fix which resolved the problem. Click on this linkto read more: & download/save the following executable: deleteupdatefiles.exe.

The error message makes the problem pretty obvious (which is a rare thing, usually error messages reveal nothing except confusion), the update control files are corrupted. These files need to be deleted, and during AVG's next attempt to update, new control files should be downloaded/created and update process should complete.
