Installation Installation of F-PROT involves copying all the files which make up the package to a separate directory on the hard disk or on a network server. One line is then added to AUTOEXEC.BAT or CONFIG.SYS to load the VIRSTOP.EXE program - see VIRSTOP.TXT for further information Earlier versions of F-PROT offered semi-automatic installation, but it was very limited - only allowed loading VIRSTOP from AUTOEXEC, and did not work on networked machines. We came to the conclusion that the installation should be handled with a dedicated "INSTALL" program and such a program now exists for the Professional version.
