Virus.DOS.SkyNet.1448 is a memory resident parasitic virus on DOS. It is named after the two programs from the Terminator movie franchise.


The virus hooks INT 21h when it is loaded into memory, and it infects any EXE executable file that is run by writing itself to the end of the file.

After that, it sets a counter and starts slowing down the system by adding dummy loops on any INT 21h call.
