    It’s no secret that I absolutely hate non-business/home-based ( ADSL/3G/other ) routers. From  a security point of view, they have a history of never-ending security issues that result in a variety of malicious attacks including DNS reflection, remote control, spam, malware infections and  other attacks.

    The end of Windows XP

    Windows XP support will officially end on April the 8th next week. This is a very important change that appears to have escaped many people. Why important?
