WHAT IS DISKNET Disknet is pro-active virus defense that prevents virus infection. Disknet is not a scanner. The DiskNet function is to eliminate the inherent problems of using scanning technology alone as an anti-virus defense. For more information on the concerns associated with scanning alone, please ask for the Reflex white paper "A False Sense of Security" with Anti-Virus solutions. Disknet is a brilliant new approach to anti-virus software, and an effective tool to enforce your company's security procedures. Every PC that has Disknet loaded is protected against: 1) unauthorized and potentially infected floppy disks, 2) boot sector and partition sector viruses, 3) unauthorized software use, and 4) unauthorized access to a PC's hard disk. Disknet provides security against virus infection, transmission, and unauthorized software installation, all without any reduced PC performance. THE DISKNET CONCEPT After utilizing a scanner to ensure floppy diskettes are virus free, Disknet places a special "signature" on each disk. As long as the floppy diskettes are used within the Disknet shield, Disknet is invisible to the user. However, if a floppy diskette leaves the shield and is written to, Disknet will force the user to re-scan the floppy to ensure it is still virus free. Typically, scanning is done by a one centrally located administrator PC within each user group. In addition to preventing virus infection, all incoming software can now be monitored via the administrator PC. ABOUT THIS DEMO This Disknet demo is not a complete working copy. Certain security features of Disknet have been disabled. In addition, Program Security Guard (PSG), an important part of the Disknet anti-virus defense which detects and prevents virus like behavior, is not included in the demo. This demo is time-disabled. It will continue to work four (4) weeks after the date you install it. This demo contains an Automatic Install -- you cannot opt to customize the install process. The Customize Install menu is available for viewing in this demo program so that you can see what options are available. This demo is the "Administrator" version of Disknet, every PC onto which you install this demo will require scanner software. This is not true for the complete version of Disknet. The scanning technology included with DiskNet is ThunderByte (file name TBSCAN.EXE). If you would like to evaluate the complete working copy of this software, please contact James C. Shaeffer & Associates, Inc. at 1-800-968-9JCS, or Reflex at 1-800-6REFLEX. INSTALLING DISKNET Once Disknet is installed, you will not have access to any diskettes that have not been authorized! There are seven important steps to installing Disknet. It is imperative that you perform each step, in order: 1) After you have created and labeled your DiskNet Demo diskette and copied the DiskNet Demo files onto the diskette, you must boot your PC from a CLEAN WRITE PROTECTED DOS DISKETTE! 2) Once the PC has been booted from the floppy, insert the DiskNet Demo Diskette. 3) Scan the hard drive using the ThunderByte scanner by typing: TBSCAN C: 4) If the PC is virus free, make a DISKNET directory on the C: drive and copy all the files from the DiskNet Demo diskette to the DISKNET directory on the C: drive. 5) Install the DiskNet software from the diskette using the INSTALL command. Use the Automatic Installation option. 6) Reboot the PC to load the DiskNet program 7) When you try and access a diskette that has not been authorized by DiskNet, you will get the following message: "UNAUTHORIZED DISK, Please have this disk checked" When this occurs, respond to the DOS error with an F, change to the DISKNET directory on your hard drive and execute the command "CHECKTB". This will scan the diskette for viruses and authorize the diskette for use within the disknet shield if the diskette is free of viruses. Alternatively, if the diskette contains no executable code, the CHECKDAT program may be used to authorize the diskette for use. CHECKDAT checks the diskette to make sure it has no executable code on it, overwrites the boot sector to eliminate boot sector infecting viruses, and writes the DiskNet signature. USING DISKNET IN THE WINDOWS ENVIRONMENT Configuring your scanner: In order to use Disknet in the Windows environment, you must first configure your scanner: 1. Click on the Reflex Disknet Icon, and select "Configure" from the pop-up menu. 2. Select the "Execute" box . The program path will default to the CHECK.DAT program. This path needs to be changed. 3. Enter the full path of the check program that is located in your scanner directory. You will find a list of supported scanners and the Disknet drivers name for the scanner towards the end of this manual, "Disknet CHECK Drivers". For example, if your are using the ThunderByte scanner, enter: C:\DISKNET\CHECKTB.EXE Authorizing a floppy diskette: 1. Execute your scanner program. (You can do this by using File Manager) 2. Disknet will then display the following options: A: test drive A: B: test drive B: X: exit checker To signature a Diskette for use, insert the disk into the appropriate drive and select the corresponding key. Disknet will automatically execute the check program designated in your configuration program path. If the diskette is virus free, Disknet will place a signature virus free, Disknet will place a signature on the diskette, authorizing the disk to be used in your environment. Unauthorized Diskettes: When an unauthorized floppy disk is accessed, Disknet will display: UNAUTHORIZED DISK in drive A: Scan and authorize disk now? When you select "yes," Disknet will automatically execute the check program designated in your configuration program path. If the diskette is virus free, Disknet will place a signature on the diskette, authorizing the disk to be used in your environment. USING DISKNET IN THE DOS ENVIRONMENT Authorizing a diskette: To authorize a diskette in the DOS environment, at the DOS Prompt: 1. Change to the directory where your scanner resides (C:\DISKNET) 2. Enter the name of the Disknet CHECK driver associated with your scanner. Disknet provides a driver which automatically executes the scanner or scanners you are using. You will find a list of supported scanners and the Disknet driver name for that scanner towards the end of this manual, "DiskNet CHECK Drivers". For example, if you are using the Thunderbyte scanner, type: CHECKTB.EXE 3. Insert the diskette you wish to scan into the appropriate drive. Disknet will then access your scanner and scan the floppy. If no viruses are found, the Disknet signature will be added to the diskette. Unauthorized Diskettes: When an unauthorized diskette is accessed, DOS will display: Data error reading drive A Abort, Retry, Fail? DO NOT be concerned when you see this - Disknet is now working! To authorize the diskette: 1. Press "F" for fail, DOS will display: Current drive is no longer valid> 2. Type c: to make the C: drive the current drive. 3. Follow the steps to authorizing a diskette in the DOS environment outlined above. Disknet CHECK Drivers A list of supported scanners and the Disknet driver name for that scanner follow: VENDOR SCANNER DRIVER NAME ============== ======= =============== Frisk Software F-PROT CHECKFP.EXE McAfee Assoc.

Insert your Disknet diskette into the drive and type DISKNET 2. You will be asked to type your Supervisor password. For demo purposes, it has been created as "DISKNET". 3. At the Supervisor Services menu, type 1 to de-install. 4. You must now power your computer off and back on to completely remove the Disknet TSR from your system. DISKNET FEATURES AND BENEFITS: We did not include all features of Disknet in this demo version. A brief product overview appears below, however we encourage you to contact us directly for more information. Disknet provides complete virus protection against all forms of infection by enforcing several anti-virus procedures. This includes scanning diskettes and signaturing them when they are verified virus free, utilizing a behavior blocker which detects and prevents virus-like behavior, and implementing utility software to prevent user by-pass. Disknet is invisible to the user and does not reduce PC performance. The Disknet Signature Approximately 90% of all viruses are transferred via floppy disks. Disknet provides total protection from diskette virus infection through the Disknet authorization process. The Disknet signature is written to a section of the diskette reserved for OEM use, therefore, even if the disk is "full" there will still be room for Disknet. The Disknet signature can be customized for your organization, or work groups within the organization. A disk with the Disknet signature can be accessed normally on unprotected computers, however if the disk is written to, it will need to be re-scanned before entry is allowed back into your Disknet protected environment. You may also establish your system so that only the addition of executable files will require re-scanning. Program Security Guard (PSG) PSG is a secondary layer of defense. It provides protection for all .EXE and .COM files on the hard drive by preventing unauthorized modification by viruses or users. PSG will stop any virus from spreading that may be missed by the scanner. In addition, PSG will stop a virus that may enter the system through non disk use (i.e. modem) by detecting and preventing virus-like activity. User by-pass protection Disknet features include utilities which will not allow users to remove Disknet or by-pass the Disknet security features. The utility package prevents access to the hard drive after booting from a floppy disk, prevents boot sector viruses from infecting the hard drive, prevents a user from removing Disknet, and provides protection from unauthorized access by requiring a password on power-up.
