I just started using Avast over AVG and plan to recommend all my clients to it, I have not seen any bad faults with AVAST then this one so far. But if this isn't fixed and I have many clients who are beginner users and will have to use System Restore on occasion because of a bad program install or bad driver install, none but me are going to remember to disable this feature- never-mind find the feature to begin with.
If this is not fixed I will have no choice but not to recommend the program. This is the OS we are talking about not a conflict with another program. A conflict with another program you can decided to either remove the program or remove the AV, but with the OS you are talking something entirely different.
