Technical Details

When an infected file is executed the virus goes resident in memory, decreasing the amount of available DOS memory by approximately 2300 bytes.

All COM files that are executed or opened (for example, copied) will be infected by the virus. Infected files grow by 1129 bytes. This change in file size is not visible when the virus is resident in memory. The virus does not infect EXE files that have been renamed to have COM extension.

The virus is encrypted with a 8-bit key. Underneath the encryption the following text can be seen:
