This should be fixed with the latest version of AVG reinstalled over the top, but if you don’t want to do that we stumbled across a little tool that does the job nicely, AVGMechanic and can be downloaded from StrategyOnline.

We can’t support the use of this tool, so if you are concerned about using it please contact your local IT support but we have found it works nicely. All it does is removes the AVG CTF files that are causing the problems and then you will be able to update.

What is a ScanDisk?

ScanDisk, also known as ‘Error Checking’ simply scans the file system and repairs any errors or bad clusters.  This just helps keep your computer running smoothly and hopefully quickly, so its worth doing.  How often depends on how much you use your machine, every three months for the home user should be fine.  Busy home machines or business machines I would say monthly ideally.

How to run a ScanDisk

1. Firstly, close all programs.
2. Click on the Start Orb.
   
3. Select ‘Computer’
   
4. Right-Click on the drive which has the Label ‘(C:)’ and then select ‘Properties’.
   
5. Select the ‘Tools’ tab and then ‘Check Now’ (Click to Enlarge Image)
   
6. Ensure that both boxes are ticked, then click ‘Start’.
   
7. Click ‘Schedule Disk Scan’ and then restart your machine.
