They must jump through the irrational and expensive hoops of the FDA, and patents are only 20 years (compare with corporate copyright of 75 years). This makes them pursue only blockbuster and knockoff drugs. Stuff for chronic diseases you're going to buy for years.
The boot device is the device from which the operating system is loaded. A modern PC BIOS (Basic Input/Output System) supports booting from various devices. These include the local hard disk drive, optical drive, floppy drive, a network interface card, and a USB device.
Boot Sector Viruses. Whereas file infector viruses infect programs on a computer's hard drive, boot sector viruses can infect hard drives and removable disks, such as floppy disks. The boot sector is an area at the beginning of a hard drive or other disk where information about the drive or disk structure is stored.ach time that program is run, the virus will infect another program or file. A second, more complex file infector is one that doesn't alter the program itself, but alters the route a computer takes to open a file. In this way, the virus is executed first, and then the original program is opened.
