Microsoft's Windows XP had a good run but if you're still using this operating system today on an Internet-connected machine you'd better consider upgrading asap. In April 2014 support will be cut off from Windows XP, meaning this operating system will no longer receive security updates, but even until that date Windows XP can hardly be called safe.
According to a new Security Intelligence Report by Microsoft, 9.1 out of 1000 Windows XP SP3 PCs are infected by malware - roughly six times higher than the infection rate found on Windows 8 machines.
The Microsoft Security Intelligence Report takes data from over one billion sources across the Windows landscape – data was drawn from Redmond real estate such as its Malicious Software Removal Tool, Exchange Online, Windows Defender and more – providing an overview into the threat landscape across Windows boxes around the world. The information was collected during the first six months of 2013.
