If you think it's ransomware then search on that phrase so you can find and they can apply a complete resolution (such as restoring from backup). Otherwise if you think it's not ransomware and only MAS was disabled intentionally then try this :
1) Restore all TXT files from /mas90/Launcher and below the most important being MNUMOD.TXT
Even if you have only a very old backup that would work. Otherwise you have to reinstall their modules to repopulate it.
2) then start up and rebuild Sy_Menu like this if I remember correctly
One way is File / Run / SYZCON
At prompt type
o=NEW("Sy_Menu_svc", %sys_ss)
? o'CompileMenu()
