How secure is Windows 8 with Windows Defender?

With the launch of Windows 8 in late 2012, there has been strong focus on safety, both from Microsoft’s own ranks and from external security experts. Recent tests show that Windows 8 lets 15 out of the 100 most common malware samples get through, even though Microsoft’s own antivirus software is enabled. This is too risky, says security expert Janus R. Nielsen from MYSecurityCenter. He believes that Windows 8 may be one of the hacker’s favourite targets in 2013.
