hi i was thinking with all the USB threats and all maybeur ESET Nod32 AV isent working becuse of some bothersome virus put it out of play. why not make a AV that you just need to run the installation and then select the installation disk (a USB) and then all the coponents installs and its ready to use and if you whant it registerd you just need to put a file in ur USB and its registerd etc. but you may think the file can be temted with like all files on a PC. well the only thing that will work there is that you make the USB uneditable. so you cant delete anything on the USB and you cant put in things in the USB. well what about the updates that ESET drops? well then we can just have the Updating tool add these files into the USB becouse it haves the promision to do so. so what do you guys think of my idea?
