Microsoft today has released the final version of their free antivirus/antispyware solution for Windows 7, Vista and XP. Microsoft Security Essentials is a free antivirus and antispyware solution which protects your computer against unwanted threats and viruses. It promises to give high-quality protection against viruses and spyware, including Trojans, worms and other malicious software.
Microsoft Security Essentials runs quietly and efficiently in the background so that you are free to use your Windows-based PC the way you want—without interruptions or long computer wait times.
Beta version of Security Essentials (MSE) was released earlier in June to a limited group of 75K in US. Those of you who are running Beta must upgrade to the final version.
Microsoft Security Essentials aka MSE supports both 32 and 64 bit versions of Windows 7, Windows Vista and Windows XP and can be downloaded for free from the link given below:
