Microsoft's Live OneCare security application once again failed to test the ability to detect and prevent malicious programs that attack Windows.
Not only that Live OneCare is also the only software among 17 security software failed in the experiment recently conducted by AV Comparatives.
Microsoft products can only detect about 82.4% of the 500,000 viruses used during testing.
This is the second time that Microsoft security products failed to test capabilities conducted by a third party.
Earlier last month, Live OneCare was also included in the list of software that failed in a similar test conducted by Virus Bulletin.
The results of the AV Comparatives test showed that most security products were satisfactory. Among them, 14 excellent products completed the test, 2 satisfactory products and 1 product - Microsoft Live OneCare - failed.
Live OneCare completely failed before the metamorphic virus - a type of malicious code that has the ability to change its shape in order to bypass the monitoring eye of security software.
" Microsoft Live OneCare presents an extremely poor ability in our experiment. That's why it is not difficult to understand if it cannot meet the minimum requirements of the experiment ," Andreas Clementi - AV Comparatives test specialist - said.
Microsoft spokesperson said the company will study the method and test results to ensure that Live OneCare will perform better in its future tests.
However, Microsoft Live OneCare still receives certification from ICSA Labs and West Point Checkpoint.
