Windows defender is not good enough for protection,you can get some other antivirus even for free !

Windows defender, in spite of getting many improvements in Windows 8 is not enough to protect your computer completely.

Windows defender is the in-built security solution for Windows 8 and it is also available for Windows XP,Vista and 7 users as standalone product called Microsoft security essentials.They both are nearly same in most ways and share the same definitions.

AV-test released a report in which they tested several popular security suites.Bitdefender,Kaspersky and Norton shared the top three spots respectively.F-Secure, GData and Avast shared the fourth place, with the Avast suite achieving the honour of being the best free protection package tested.But Windows defender disappointed a lot.It could just protect you from 79% of realtime threats while the top four managed to give protection rates ranging from 98% to 100%.Windows defender showed poor protection rates than any other antivirus program available.

So,I recommend all the users to better use any one of the top solutions.If you don’t want to shell out money for antivirus then consider avast! free antivirus or AVG free antivirus which provides excellent protection against threats for free.
