computer viruses

The term usually used to define a computer virus is:' A computer virus is often malicious software which replicates itself'

- COMPUTER VIRUSES ARE BASICALLY PROGRAMS, LIKE A SPREADSHEET OR A WORD PROCESSOR.

- PROGRAMS WHICH CAN INSERT EXECUTABLE COPIES OF ITSELF INTO OTHER PROGRAMS.

- PROGRAMS THAT MANIPULATES PROGRAMS, MODIFIES OTHER PROGRAMS AND REPRODUCE ITSELF IN THE PROCESS.

However, " computer virus " is just another name for a class of programs.  They can do anything that another program can.

]]>

The only distinguishing characteristic is the program has ability to reproduce and infect other programs.

- PROGRAM WHICH HAS CAPABILITY TO EXECUTE THE MODIFICATION ON A NUMBER OF PROGRAMS.

- CAPABILITY TO RECOGNIZE A MODIFICATION PERFORMED ON A PROGRAM.(THE ABILITY TO PREVENT FURTHER MODIFICATION OF THE SAME PROGRAM UPON SUCH RECONDITION.)

- MODIFIED SOFTWARE ASSUME ATTRIBUTES 1 TO 4.

A computer virus can only be put into your system either by yourself or someone else.  One way in which a virus can be put into your computer is via a Trojan Horse.

-TROJAN HORSE IS USUALLY CONTAMINATED IN DISKS WHICH ARE PARTICULARY PIRATED COPIES OF SOFTWARE.  IT IS SIMPLY A DAMAGING PROGRAM DISGUISED AS AN INNOCENT ONE.  MANY VIRUSES MAYBE HIDDEN IN IT, BUT T.H. THEMSELVES DO NOT HAVE THE ABILITY TO REPLICATE.

Viruses also can be spread through a Wide Area network (WAN) or a Local Area Network (LAN) by telephone line.

For example down loading a file from a local BBS.

BBS(bulletin board system)-AN Electronic mailbox that user can access to send or receive massages.

However, there seems to be countless numbers of ways to become infected.  Every-time you down loads a program from somewhere or borrowed a disk from a friend, you are taking a risk of getting infected.

a.> Fill Up your P.C. with Garbage:As a virus reproduces, it takes up space.  This space cannot be used by the operator.  As more copies of the virus are made, the memory space is lessened.

b.> Mess Up Files:Computer files have a fixed method of being stored.  With this being the case, it is very easy for a computer virus to affect the system so some parts of the accessed files cannot be located.

c.> Mess Up FAT:FAT(the File Allocation Table) is the method used to contain the information required about the location of files stored on a disk.  Any allocation to this information can cause endless trouble.

d.> Mess Up The Boot Sector:The boot sector is the special information found on a disk.Changing the boot sector could result in the inability of the computer to run.

e.> Format a Disk/ Diskette:A virus can simply format a disk as the operator would with the format or initialise command.

f.> Reset The Computer:To reset the computer, the operator or the user only has to press a few keys.  The virus can do this by sending the codes to the operating system.

g.> Slowing Things Down: As the name implies, the object of the virus is to slow down the running line of the program.

h.> Redefine Keys: The computer has been program to recognize that certain codes/ signals symbolize a certain keystroke.  The virus could change the definition of these keystrokes.

i.> Lock The Keyboard: redefining all keys into an empty key.

When signs of a virus attack have been recognized,the virus has already reproduced itself several times.Thus, to get rid of the virus, the user has to hack down and destroy each one of these copies.  The easier way is to:

1. Have the original write protected back-up copy of your operating system on a diskette.

2. Power down the machine.

3. Boot up the system from the original system diskette.

4. Format the hard disk.

5. Restore all back-ups and all executable program.

*If it's not effective, power down and seek for professional help*

a.> OVER-WRITING VIRUSES

b.> NON-OVERWRITNG VIRUSES

c.> MEMORY RESENDENT VIRUSES

Viruses are a day to day reality.  Different activities leads to different exposure.  To protect oneself from a virus, several things can be done:

1. Avoid them in the first place.

2. Discovering and getting rid of them.

3. Repairing the damage.

The simple thing that can cut down on exposure rate are to:avoid pirate software, checking programs that have been down loaded form the BBS before running them.  Make sure that you have sufficient backups.

The pace at which new antiviral products have been pouring onto the market has accelerated rapidly since the major infection of 1988.  Indeed, by early 1989, there were over 60 proprietary products making varied claims for effectiveness in preventing or detecting virus attacks.

 

 

Getting the Right Computer Software

Computer software is a vast term used to describe a collection of computer programmes, procedures and documentation that all perform tasks on a computer system. Computer software is the applications that we use on our computers such as office programmes and even windows itself. Computer software is any programme that we load onto and install on our computers.

Computer software is usually brought in CD format and is then installed onto our computers from this. Any new programmes etc that you buy for your computer can be classed as a form of software. Without software you wouldn’t get very far with the use of your computer.

When software is placed or opened on your computer it is loaded into the RAM and executed through the central processing unit (CPU) it is then available for you to use.

Software comes in three main types, the first being system software. This helps to run your computer hardware as well as your computer system. The second is programming software. This provides tools to assist programmers in writing computer programmes, such as text editors, compliers, interpreters and linkers. The last form of software is application software. This allows end users to accomplish one or more specific tasks. Typical applications include industrial, business, educational, medical databases and computer games; businesses being the biggest users of application software.

Best answer:

Answer by heyfaye
for windows:
if you've already deleted them they might still be in the recycle bin. empty your recycle bin. or you can go to Start > Programs > Accessories > System Tools > Disk Cleanup to clear temporary files and compress old files. after disk cleanup choose Disk Defragment to further clean your system. this will take a while so close any running programs.
