- The documentation for PKZIP v2.04c contains the following item.
-
- It sounds awful strange to me. If I type out a text file that contains
- one of these "bombs" do I face the risk of introducing a virus into
- my system?
-
- If anyone can give me some insight into this, I would appreciate it if you
- could respond via email. Thanks.

- PKSFANSI.COM
-
- PKSFANSI (PK Safe ANSI) is a Terminate and Stay Resident program that disables
- ANSI Keyboard Key Reassignments, thereby preventing "ANSI bombs" embedded in
- any text file (such as README files) or output by any program.
-
- Normally, ANSI sequences that redefine the keyboard could be hidden inside ANY
- text file or program, and could be executed completely unnoticed until it is
- too late. PKSFANSI intercepts calls to the ANSI.SYS or other ANSI device
- drivers, and filters out any keyboard reassignments, while allowing other ANSI
- sequences through unaltered.
-
- If a keyboard key reassignment is attempted, PKSFANSI will intercept the
- sequence and discard it. PKSFANSI also will BEEP to alert you that a
- reassignment was attempted.
-
- PKSFANSI requires less than 1k bytes resident RAM, and should work with any
- ANSI driver, such as the standard ANSI.SYS driver, NANSI, ZANSI, DVANSI, etc.
- Note that if you use a memory resident ANSI driver, such as the DESQview
- DVANSI.COM driver, PKSFANSI should be loaded after the ANSI driver is loaded.
