Microsoft Security Essentials is several software products from Microsoft that make up the anti-malware package: Trojans, viruses, spyware, rootkits. MSE is not a cross-platform product and runs only on Windows operating systems (including Vista, Windows 7, Windows 8 and Windows 9). Moreover, the operating system on which the program is to be installed should be validated beforehand.
Microsoft Security Essentials was developed as a replacement for Windows Live OneCare and Windows Defender and is intended for use on home computers.
The license under which Microsoft's anti-virus package is distributed allows commercial use within a small business, and the number of copies used by a single firm has been increased to 10.
Microsoft Security Essentials was installed on most computers in the U.S. and was one of the top four antivirus programs in the world.
Features of Microsoft Security Essentials
MSE's functionality is similar to its predecessor, Windows Defender, which is automatically disabled during installation of the newer MSE. Microsoft Update publishes a semblance of antivirus databases three times a day, which are downloaded automatically by the company's antivirus product. Updates can also be downloaded manually from the Microsoft Security Portal.
According to the default settings, the archives are unpacked first and then checked (can be unpacked with a PC archiver). E-mails and their attachments are also scanned. System restore points are created before deleting malicious code. MSE does not require any RAM and requires no more than 4 megabytes per day.
