SPECTRUM OF HARM. "Just as biological viruses range from being quite harmless to lethal, computer viruses may simply cause a harmless message to appear on your screen occasionally, or may render your system inoperable." https://lnkd.in/dhKz_EK View in LinkedIn

"FILE INFECTOR VIRUSES are those that infect other files or programs on your system. They operate in a number of ways. Once the original 'host' program is run, the virus can stay resident or 'live' inside your systems memory (RAM) and infect programs as they are opened, or they can lay dormant inside another program. Each time that program is run, the virus will infect another program or file." https://lnkd.in/dhKz_EK View in LinkedIn

"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. Symptoms of a boot sector virus may be a computer that is unbootable or gives error messages upon booting. Frustratingly, boot sector viruses may be present with no noticeable problems." https://lnkd.in/dhKz_EK View in LinkedIn

"MACRO VIRUSES use an application's own macro programming language to distribute themselves. Macro viruses do not infect programs; they infect documents. Macro viruses typically arrive in an infected document, a price list written with MS Word for example." https://lnkd.in/dhKz_EK View in LinkedIn

THE STUDY OF THE EARTHWORM (by Charles Darwin) took 40 years of experimentation on a pool table to complete (1881 in a book titled The Formation of Vegetable Mould through the Action of Worms, with Observations of their Habits). https://lnkd.in/d4AyW4h View in LinkedIn

"A WORM is a piece of code that can make fully functional copies of itself and travel through a computer network and/or across the Internet through a number of means. A worm does not attach themselves to other programs like traditional viruses, but creates copies of itself, which in turn create even more copies." https://lnkd.in/dhKz_EK View in LinkedIn

WORM TRACKS. "The computer 'worm' is so-called because of the way in which 'rogue' computer code was originally detected. Printouts of computer memory locations would show random 'wormhole' patterns, much like that of the patterns on worm-eaten wood. The term eventually became shortened and used to describe viruses that could 'worm' or propagate across networks and the Internet, leaving copies of themselves as they travelled." https://lnkd.in/dhKz_EK View in LinkedIn

WORMS VERSUS VIRUSES. "Worms are another form of software that is often referred to as a computer virus. Unlike viruses, worms are programs that can run independently and travel from machine to machine across network connections; worms may have portions of themselves running on many different machines. Worms do not change other programs, although they may carry other code that does, such as a true virus." https://lnkd.in/eCG7b3z View in LinkedIn

VIROID. "True viruses have two major components: one that handles the spread of the virus, and a “payload” or “manipulation” task. The payload task may not be present (has null effect), or it may await a set of predetermined circumstances before triggering." https://lnkd.in/eCG7b3z View in LinkedIn

"COMPANION VIRUS, is not really a virus at all, but a form of trojan horse that uses the execution path mechanism to execute in place of a normal program. Unlike all other viral forms, it does not alter any existing code in any fashion: companion viruses create new executable files with a name similar to an existing program, and chosen so that they are normally executed prior to the “real” program." https://lnkd.in/eCG7b3z View in LinkedIn
