 Microsoft isn't too happy with the results of a recent test that found fault with its antivirus software.
 
For the second time in a row, the company's Security Essentials failed to win certification from AV-Test, a German-based testing lab that evaluates the efficacy of antivirus products. Out of 25 programs tested, only three failed to gain AV-Test's thumb's up for certification.
 
Microsoft's Forefront Endpoint Protection, which is geared toward corporate customers, also failed to gain certification.
