Question 1
A. Computer virus: The virus is essentially a program, which run itself in the targeted computer without user awareness and approval and reside in host computer programs, or the host computer media files like videos or images or any type of file that is stored into the host computer hard drive, the most critical part of the host data files is called boot sector/block, this part which is usually part of the hard desk, contains machine code that is loaded into random access memory ( RAM ) is responsible to initialize the process of a computer operating system, this process is called booting, and when the virus live into this sector, it will be loaded every time the computer is booted, which create the most damage effect to the computer.
Viruses damage computers, some viruses steal…show more content… • Perform daily scans: sometimes viruses can escape system active antivirus software and infect a system, the huge numbers of new threats make it very hard for software to detect all of them immediately, in other cases users intentionally instruct antivirus software to allow virus program to run for different reasons. Therefore, running full system scans on entire hard drive will detect and remove these viruses.
• Disable auto run: many viruses attach themselves on media connected to the system, such as external hard desks, or flash desks, when these are connected to a computer, the viruses live inside them will attack, therefore disabling the auto run will prevent them from coping themselves into the host computer.[2]
