For the installable version of VirusScan for DOS, take the following steps: a. Execute the INSTALL.BAT program. b. Follow the on-screen instructions. By default, McAfee's installation program makes a directory on the hard disk drive named C:\MCAFEE\VIRUSCAN and copies the program files to that directory. The installation script adds the directory to the path statement in your AUTOEXEC.BAT file and adds two lines that call and recall the VShield program to provide on-access virus prevention. For the most complete virus protection, McAfee recommends using the /ANYACCESS switch. or 2. For the non-installable version of VirusScan for DOS, take the following steps: a. Make a directory on your hard disk drive. b. Copy the files to that directory. c. Add that directory to the path statement in your AUTOEXEC.BAT file. If you would like to perform a "silent" installation of VirusScan for DOS, requiring no user interaction and using all default settings, add -s (i.e. SETUP.EXE -s) to the setup command when you install the product. * PRIMARY PROGRAM FILES FOR VIRUSSCAN FOR DOS * Files located in the Install directory: ======================================= SCAN.EXE = VirusScan for DOS program README.1ST = McAfee information PACKING.LST = Packing list VALIDATE.EXE = Authenticity validation program SCAN.DAT = Virus scan definition data NAMES.DAT = Virus names definition data CLEAN.DAT = Virus clean definition data WHATSNEW.TXT = What's New document AGENTS.TXT = McAfee Authorized Agents * TESTING YOUR INSTALLATION * The Eicar Standard AntiVirus Test File is a combined effort by anti-virus vendors throughout the world to come up with one standard by which customers can verify their anti-virus installations. To test your installation, copy the following line into its own file and name it EICAR.COM. X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H* When done, you will have a 69- or 70-byte file. When VirusScan is applied to this file, SCAN will report finding the EICAR-STANDARD-AV-TEST-FILE virus. It is important to know that THIS IS NOT A VIRUS. However, users often have the need to test that their installations function correctly. The anti-virus industry, through the European Institute for Computer Antivirus Research, has adopted this standard to facilitate this need. Please delete the file when installation testing is completed so unsuspecting users are not unnecessarily alarmed. * UNINSTALLING THE PRODUCT * 1. Execute VSHIELD/REMOVE to remove VShield from memory, then remove the files from your hard drive and remove any lines in your AUTOEXEC.BAT file that call VShield. If an error message is displayed indicating that VShield could not be removed from memory, take the following step. 2. Edit your AUTOEXEC.BAT file and remove the line that calls VShield, then reboot your system. On restarting your system, VShield will not be loaded into memory and you can remove the files from your hard drive. Note: If the files are removed from your hard drive prior to removing VShield from memory, an error message will be displayed until you remove VShield from memory or restart your system. _____________ DOCUMENTATION For more information, refer to the VirusScan User's Guide, included on the CD-ROM versions of this program or available from McAfee's BBS and FTP site.

Q: How much conventional memory is required to run VirusScan for DOS? A: A minimum of 490K of free coventional memory is recommended to run VirusScan for DOS. Q: What is the difference between the VShield DOS TSR and VirusScan for DOS? A: #1 VShield installs itself in memory and stays resident in order to monitor your system for viral activity. If an infected program is executed or an infected boot sector is accessed, VShield will display a warning that a virus is present. A: #2 VirusScan for DOS is an on-demand scanner that allows you to perform a complete or partial scan of your computer at any time. VirusScan for DOS can run customized scans through a large set of command line switches. Q: How can I run VirusScan for DOS from a Netware login script without running out of memory? A: If you are having memory problems when trying to run VirusScan for DOS from a NetWare login script, take these steps to resolve the issue: 1. Rename LOGIN.EXE to LOGIN1.EXE and remove any references to VirusScan. 2. Create a batch file named LOGIN.BAT. 3. On the first line of the batch file, run your scan with whatever switches you want to include. 4. On the second line of the batch file, run LOGIN1.EXE. By taking these steps, you eliminate the problem of having LOGIN.EXE and SCAN.EXE in memory at the same time. This allows VirusScan for DOS to run and your login script to be processed without problems. Q: Can I clean the Master Boot Record (MBR) of a Windows NT file system (NTFS) formatted hard drive? A: Yes. Take these steps to clean the MBR. Boot the Windows NT computer from a virus-free DOS bootable (system) diskette. Then run VirusScan for DOS; SCAN C: /BOOT /CLEAN. This will clean the NTFS Master Boot Sector and allow Windows NT to successfully reboot from the hard disk drive. However, VirusScan for DOS will not be able to read the rest of the NTFS partition. After starting Windows NT, execute VirusScan for Windows NT to detect and clean Windows NT file infections. Q: Can I update VirusScan's data files to detect new viruses? A: Yes. If your data files are dangerously out-of-date, VirusScan for DOS will prompt you to update them. If you have Internet access, you can download updated VirusScan data files from the McAfee Web Site, BBS, or other online resources. To download from the McAfee Web Site, follow these steps: 1.
