Technical Details

An encrypted virus that contains the following text message:

I'm a non-destructive virus developed to study the worldwide diffusion rate.  I was released in September 1990 by a software group resident near Como lake (north Italy).    Don't worry about your data on disk.  My activity is limited only to auto-transferring into other program files.  Perhaps you've got many files infected.  It's your task to find and delete them   Best wishes
