61 Under OS/2 2.0+, could a virus infected DOS session infect another DOS session?
Each DOS program is run in a separate Virtual DOS Machine (their memory
spaces are kept separate by OS/2). However, any DOS program has almost
complete access to the files and disks, so infection can occur if the
virus infects files; any other DOS session that executes a program
infected by a virus that makes itself memory resident would itself
become infected.
Also, bear in mind that generally all DOS sessions share the same copy
of the command interpreter. Hence if *it* becomes infected, the virus
will be active in *all* DOS sessions.
