Windows XP Support Ends: Buy and Install Security Software
As part of its termination of Windows XP support, Microsoft is no longer proving Microsoft Security Essentials for Windows XP. It also has ceased providing security updates to XP computers with Security Essentials already installed.
Therefore, security for any PCs that haven’t undergone a Windows XP upgrade is now in your hands. That means investing in a good security software suite and installing it.
It won’t take long for viruses, trojans, worms and all sorts of malware targeting unprotected Windows XP computers to propagate, so the sooner you put regularly updated commercial security software on that PC, the better.
Turn on the PC’s firewall for added protection from Internet-based attacks.
