3. How a virus spreads
The most common way of getting a virus these days is to open an email attachment. Many viruses have been especially designed to take advantage of the way people send emails to each other.
Another way is to load an infected file into your computer from some kind of storage device
-
floppy disk
- memory stick
- CDROM
- DVD
Note: The CD and DVD products from reputable companies are very unlikely to contain a virus. It is the personal 'burned' ones that are a potential problem. [Type 'commercial cd virus' in the search box opposite]
It is also possible to pick up a computer virus through what is known as 'peer to peer' file sharing networks. These are internet networks that are used by people to share files amongst each other.

In the search box on the right, type the term "peer to peer virus" and see what you can find out for yourself |
There is often no immediate evidence that a virus has been transmitted to a computer, and the user may remain unaware of it until it causes something to go wrong.
Basically a virus is spread by allowing it to run (technical term: "execute") on your computer, so any executable file or computer program can contain a virus.
