(DOS MicroSoft AntiVirus) Starting with DOS 6, MSAV is a menu-driven utility that scans memory and disk for viruses. To run it, type msav. To run the program automatically each time you start the computer, add one of the following lines in your AUTOEXEC.BAT file:

     msav /p     scan memory and drives
     msav /p /l  limit scan to local drives
                  if network drives are used

A memory resident antivirus utility is also included that will continually check for viruses. To load it, type vsafe. To unload it, press Alt-V and Alt-U.

For Windows Users

A Windows version of MSAV.EXE is included with DOS 6 called MWAV.EXE. This is run from an icon in Windows, which is installed in the Microsoft Tools Program Group. Windows 95 did not include a virus program in its initial introduction.
