You can never be invisible to your ISP, although it's probably been MediaDefender or some other company searching gnutella for copyrighted material.
I don't think your ISP can order you to turn off sharing, since sharing files (if you are not infringing anybody's copyright) is completely legal.
Just stop sharing those programs, for it is very likely that in the name of Adobe or Microsoft a company like MediaDefender sent a letter to your ISP telling him that you are sharing copyrighted material. |
