"Latest Windows Defender definition updates."

Windows Defender Definition Updates is the update definitions file to ensure that the Windows Defender package remains up to date. Windows Defender was originally a malware scanner and removal application for Windows 98. Microsoft purchased Giant AntiSpyware, written in VisualBasic in 2006 and then redeveloped the app in C++ which made it run faster. The app was originally given away with versions of Windows, but with Windows Vista and 7 the app morphed into an anti-virus app as well. It is important to keep Windows Defender definition files updated to ensure all known viruses are caught before the PC becomes infected.
