What Are Virus And Spyware Definitions

A computer virus is a computer program that can copy itself and infect a computer. The term "virus" is also commonly but erroneously used to refer to other types of malware, including but not limited to adware and spyware programs that do not have the reproductive ability. A true virus can spread from one computer to another (in some form of executable code) when its host is taken to the target computer; for instance because a user sent it over a network or the Internet, or carried it on a removable medium such as a floppy disk, CD, DVD, or USB drive.

Spyware is a type of malware that can be installed on computers, and which collects small pieces of information about users without their knowledge. The presence of spyware is typically hidden from the user, and can be difficult to detect. Typically, spyware is secretly installed on the user's personal computer. Sometimes, however, spywares such as keyloggers are installed by the owner of a shared, corporate, or public computer on purpose in order to secretly monitor other users.

When you use Antivirus Software's, it is important to have up-to-date virus and spyware definitions. Definitions are files that act like an ever-growing encyclopedia of potential software threats. Antivirus uses definitions to determine if software that it detects is a virus, spyware, or other potentially unwanted software, and then to alert you to potential risks. To help keep your definitions up to date, Most antivirus updates its virus definition automatically.

Microsoft Security Essentials is the name of Microsoft’s latest Anti-Virus/Anti-Spyware software for Windows operating system. It is already being tested internally at Microsoft and was launch in September last year.  Read more: http://www.bench3.com/2010/08/microsoft-security-essentials-for.html

Security Essentials works with Microsoft Update to install new definitions automatically as they are released. You can also set Security Essentials to check online for updated definitions before scanning.
