AVG Antivirus 8 doesn't update

I recently upgraded my AVG 7.5 to 8. I have been using and recommending AVG for home users since a long time now primarily due to two reasons:

• It is free.
• All major antivirus solutions are trying to become all-in-ones with integrated firewall, anti-spyware etc etc. While this is beginner friendly, it also makes them pretty resource hungry. While Avg Pro is in the same race, I still see Avg free as much lighter on resources.
  

Having said that, I also feel that an average Avg user needs to be computer literate.

I didn't face any issues with AVG 7.5 other than the update server being down sometimes. However, I ran into an issue as soon as I installed AVG 8. After a few auto-updates that went fine, it suddenly stopped updating, giving an error message - "Invalid CTF file". At first the AVG update server was down, but this went for longer than I would expect the server to be down.

I googled around a bit and found this. The solution was straight-forward

• Goto C:\Documents and Settings\All Users\Application Data\avg8\update\download
• Delete the 2 .ctf files there.

And it worked. No issues with AVG 8 after that. However, I am pretty surprised by that AVG has not understood the gravity of the situation and have failed to provide an automatic patch. I agree that this is a free product, but how do you expect your free users to convert to pro if your free product will fail to provide the security that it promises. Issues like these can single-handedly kill a product.
