- This is a virus checker for the Amiga. This program will check your floppy
- disks for signs of non standard boot code (viral infection).
-
- USAGE: VCheck1.9 df0: Check drive df0: for the virus
- VCheck1.9 df3: Check drive df3: for the virus
- etc.
-
- VCheck1.9 ? Print Usage information
- VCheck1.9 -?
-
- If the virus is found on any of your disks you can use the DOS Install
- command to remove it.
-
- WARNING: Installing to some commercial disks (games) can be fatal.
- normally you should only install to DOS boot disks.

- This program has been updated to VCheck1.9 as of 1-7-88. VCheck1.9
- has changed since release 1.2. VCheck1.9 will now identify a disk as
- one of three types, NON-BOOTABLE DISK, NORMAL DOS BOOT DISK, DISK WITH
- NON STANDARD BOOT CODE. This release will detect but NOT indentify all
- non standard boot blocks. If VCheck1.9 finds a NON STANDARD boot block
- use VCheck1.2 to indentify it as SCA #1 or SCA #2. If VCheck1.2 does
- not make a positive indentification the boot block is either a new VIRUS
- or a valid commercial bootblock. If the disk in question is not a commercial
- product you should assume that it is infected with a new VIRUS and if
- possible send a copy of the disk to:
- Bill Koester (CATS)
- 1200 Wilson Drive.
- West Chester, PA 19380
- (215) 431-9355
-
- for identification. VCheck 1.9 will not check memory for a VIRUS use
- VCheck 1.2 with no parameters.

- There are some disk viruses which have been recently infecting bootable
- disks. When a machine is booted with an infected disk, the virus
- installs itself in memory and wedges itself into some vectors. When
- the infected machine is rebooted, the virus writes itself to the boot
- disk. The virus is written to the boot blocks and is fairly harmless
- to normal Workbench type boot disks. But it can be "fatal" to disks
- with specialized boot blocks (such as some commercial games, etc).
-
-
- TO PROTECT OTHERS:
- ------------------
-
- Do not distribute any bootable disks, without first making sure that
- the masters are free of infection. (Note - A bootable disk is any
- disk the Amiga accepts at the Workbench prompt)
-
- TO PROTECT YOURSELF:
- --------------------
-
- If you are not sure a machine is clean, turn off the machine for
- 30 seconds before booting on it.
-
- Write-protect your disks before booting with them, especially if you are
- booting on someone else's machine or booting after someone else
- has used your machine.
-
- Use VCheck to make sure your disks and memory are free of known viruses.
-
- TO DETECT THE VIRUS:
- --------------------
-
- Use VCheck1.9 as described above.
-
- TO GET RID OF THE VIRUS:
- ------------------------
-
- If your boot disk is infected, and it has no specialized boot code, use
- the CLI Install command on it to remove the virus.
-
- (Note - Any infected boot disk that still works probably had no
- specialized boot code)
-
- Do not Install uninfected disks (you could destroy special boot code).
- Do not Install non-boot disks (you'll make them susceptible to the virus).
-
- Usage: Install dfn: (Example: Install df0:)
-
- Write protect the disk.
- Check the disk with as described above to make sure it is clean.
- Turn off your machine for 30 seconds.
- Now boot with the clean write-protected disk.
-
- Use VCheck1.2 to make sure memory is clean, and VCheck1.9 to check your
- other boot disks. Use the CLI Install command to remove the
- virus from any normal boot disk which is infected.
