PROGRAMS

- A VIRUS IS A COMPUTER PROGRAM THAT EXECUTES WHEN AN INFECTED PROGRAM IS EXECUTED. THEREFORE, ONLY EXECUTABLE FILES CAN BE INFECTED

- BY DEFINITION, A VIRUS INFECTS OTHER PROGRAMS WITH COPIES OF ITSELF

o MAY SIMPLY CLONE ITSELF
o MAY DAMAGE OTHER PROGRAMS AND DATA
o SOME SELF-DESTRUCT WHEN DONE

- VIRUS PROGRAMS ARE OFTEN QUITE SMALL, ONLY A FEW LINES OF CODE

- CAN BE HIDDEN IN HEALTHY SOFTWARE AND QUITE HARD TO FIND

- CAN INFECT ANY COMPUTER, CAN BE TRANSMITTED OVER ANY LINES. REPRODUCE RAPIDLY, MAKING IT DIFFICULT TO TRACE BACK TO SOURCE




TYPES OF VIRUSES


- A VIRUS MAY ATACH ITSELF TO OTHER PROGRAMS AND HIDE IN THEM. OR IT MAY INFILTRATE THE COMPUTER’S OPERATING SYSTEM

- USUALLY CONTRACTED FROM EXTERNAL SOFTWARE SOURCE – VIRUS HOST PROGRAMS MADE DELIBERATELY ATTRACTIVE TO VICTIMS (E.G., E-MAIL MESSAGE, GAME)

- CAN ACT IMMEDIATELY OR LIE DORMANT FOR A PERIOD OF TIME (E.G., MICHELANGO VIRUS, ON MICHELANGO’S BIRTHDAY) OR UNTIL SOME EVENT (1-2-3 VIRUS WHEN 1,2,3 TYPED)
