Update: The bug has been fixed in version 8.0.233 - 
I have recently installed AVG anti-virus Free 8.0.176 on a machine when I discovered a pretty big GUI (general user interface) bug.
Look here:
To replicate the bug. just go into the license section and you will see that the 'Register' button overlaps the 'Back' button
To be quite honest, I was surprised that even though this software is used by '80 million users'*, obvious bugs like these are still not ironed out.
Subsequently, I reported the bug on the AVG Free forums, but was surprised to hear that no employees from AVG Technologies actually actively take part in the forums, only oversee.
Anyway, I was later told my comment should have been seen by the AVG Team and that it would be fixed in the next program update. Lets hope so!
