What is the cost of Microsoft virus removal tool? When was it first released? What is the size of the file? How regularly is it updated?
The Microsoft Windows Malicious Software Tool is developed for Windows OS to remove the virus and is available for free. It was first introduced on January 13, 2005. It lacks real-time protection and is an on-demand anti-virus tool that scans for viruses only when called upon and for specific widespread malware. The size of the file is 56 MB. The updates for the tool are released on Patch Tuesday that’s the second Tuesday of every month.
If you are referring to antivirus programs developed by Microsoft, I guess they have two: Microsoft Security Essentials or MSE and Windows Defender. Microsoft Security Essentials is designed for Windows Vista and Windows 7 only. It will not work on any earlier or newer operating system. Windows Defender, on the other hand, comes pre-installed with Windows 8.x and Windows 10 as well as Windows RT and Windows RT 8.1.
Though Windows Defender is designed to work with Windows 8 and higher, you can also install it on Windows 7 but the only limitation is that it will only provide you protection against spyware. Full malware protection is supported only on Windows 8 and higher. If you have Windows Vista or Windows 7, you can download Microsoft Security Essentials.
If you want Windows Defender, you have to upgrade your operating system to Windows 8 or higher. If you have Windows 8, you should upgrade to the latest Service Pack, Windows 8.1.
