The Lagob.A virus looks for Matlab files (.m) in the current folder. When it find such files, it tries to infect them by writing its code line by line on top of the file, i.e by prepending its code to the existing .m file. To avoid infecting a file multiple times, the virus uses an infection marker and does not try to infect already infected files. The virus does not have any payload or visual effects.
