F-Secure Anti-Virus for DOS

Update: March 3, 2014
This software is no longer available from F-Secure

F-Secure offers a free antivirus program for DOS. This can be run from a command line within windows or you can boot the system from a DOS floppy or CD when you can't get Windows to start properly or want to run an antivirus program from outside of Windows. The program is available from F-Secure at Free Virus Removal Tools, which provides a link for downloading the software from F-Secure's FTP site at ftp://ftp.f-secure.com/anti-virus/free/. Download fp-xxx.zip, where "xxx" is the latest version shown on the FTP site, e.g. fp-312d as of October 9, 2006. Then download the latest virus definitions from ftp://ftp.f-secure.com/anti-virus/updates/f-prot/dos/. You will need macro.def, sign.def, and sign2.def. The macrodef2.zip file is simply a zipped version of macro.def with a PGP signature in macro.asc; you don't need it if you download macro.def. Place macro.def, sign.def, and sign2.def in the same directory where you place the f-prot program that is in the fp-xxx.zip file you downloaded, overwriting the older versions that are in that zip file.

macro.def - macro viruses definition database for F-Prot for DOS
sign.def - binary viruses definition database for F-Prot for DOS
sign2.def - additional binary viruses definition database for F-Prot for DOS

To run the program, obtain a command prompt and change your working directory to the directory where you unzipped F-Prot, e.g. cd \f-prot. Then start the program with the command f-prot for an interface that will allow you to select options from a menu. If you don't have a floppy drive in the system you are using, then you need to use f-prot /nofloppy instead.
