Microsoft has released a minor update to its Windows Defender antispyware system. The update includes some changes to the user interface, 64-bit support, and improved real-time protection. They have updated Windows Defender to ensure that it will monitor the Operating System’s key files and make sure they do not get infected.
Microsoft has been doing a very good job with their antispyware software and have acquired many users from the testing phase of Windows Defender (originally named Windows AntiSpyware). They are aiming to protect millions of Windows users by incorporating Windows Defender with the final release of Windows Vista. It looks like they could be giving Ad-Aware a run for their money.
