Sources of Computer Viruses
Topic Content:
- Sources of Computer Viruses
- zip disks, email, downloads, etc.
There are so many ways computers can get infected with viruses. Below is a list of ways through which our computers can contract computer viruses.
Infected Zip Disks:
Do not put a flash disk that has been in another computer into your computer, without scanning it for a virus.
Emails:
Email messages do not carry viruses. It is the .exe, com, or other types of executable files that can carry a virus. Note that email allows you to send and receive messages through the Internet, but this is one way your computer can get infected with a virus.
Infected CD/DVD-ROMS:
These are storage devices used for storing software. However, when these CD/DVD ROMS are used to copy files, from one infected computer to another, the virus follows.
Infected Flash Disk:
Flash disks or Flash drives connect to a computer through a USB port. It is the most common storage device today, and it has become a major tool for transmitting viruses from one computer to another. Be wise. Do not put a flash disk that has been in another computer into your computer, without scanning it for a virus.
From a Computer Network:
All the nodes on a network are linked together by a big computer called a server. The server and the clients constantly share information. It is in the process of sharing resources and information, that viruses quickly spread to other users, especially if one of the files shared is infected. So be careful.
Internet Downloads:
Just browsing the Internet does not put your computer at risk of getting infected, but program downloads will do you a great deal of harm. Nowadays, the Internet is the main area where computer viruses spread like wildfire. These viruses can be attached to various types of Internet files, such as movies, games, and graphics that people, especially students, download from the Internet. So, be careful how you download games.
Illegal Duplication of Software:
Some viruses were written and installed to prevent unauthorized users of the computer, from duplicating software copies. So, when people do some sort of gate-crashing, they gate-crash into a virus and end up destroying their own good files/data in their computers.
