AVG Claims Zero Day Protection

We've all heard it before from other antivirus companies claiming that they have the solution to zero-day type malware, but they never seem to live up to expectations. AVG is the latest to introduce detection of Zero-Day malware before it does harm to your computer without knowing what it is looking for. I've always loved the occult side of computer technology. AVG has not made any claims of protection from zero day threats in its previous software so it must be fairly confident that this version of screening must do something a little different.
