Line.908

It is not a dangerous memory resident parasitic virus. It hooks INT 9 (keyboard), 21h and writes itself to the end of COM files (except COMMAND.COM) that are executed. Depending on its internal counter (after 3000+ characters that entered from keyboard) it resets INT 9, hooks INT 1Ch and manifests itself with a blinking (on fast PCs) or moving (on old PCs) screen line.
