COMPUTER VIRUS AND ANTIVIRUS REPORT
[attachment=17812]
SUMMARY
A Virus is basically an executable file which is designed such that first of all it should be able to infect documents, then; it has to have the ability to survive by replicating itself and to avoid detection. Computer viruses can be classified into several different types:
1. File or program viruses:- they infect program files likes files with extension like .EXE, .COM, .BIN e.t.c. some viruses just replicate while others destroy the program being used at the time.
2. Boot sector viruses (MBR or master boot record):- Boot sector viruses can be created without much difficulty and infect either the master boot record of the hard disk or floppy drive.
3. Polymorphic viruses: - they are the most difficult viruses to detect. They have the ability to mutate this means that they change the viral code know as the signature each time it spreads or infect.
PROBLEM SOLVED
Basically the problem solved in this seminar was the defining of antivirus which deals the solution to the threat of viruses in a computer system.
Also the basic techniques that are been used include scanning, monitoring, and also integrity checking in other to prevent viruses from infection.
CLAIM CONTRIBUTION
Computer viruses are not inherently destructive. The essential feature of a computer program that causes it to be classified as a virus is not its ability to destroy data, but its ability to gain control of the computer and make a fully functional copy of itself. It can reproduce, when it is executed, it makes one or more copies of itself.
Not all computer programs that are destructive are classified as viruses because they do not all reproduce and not destructive.
