What
is a Computer Virus?
A Computer virus is designed to alter the way your
computer works, without your knowledge or consent.
How are computer viruses transmitted?
Viruses are usually disguised and can enter your computer by:
- Receiving emails and opening
email attachments
- Internet downloads
- Web pages
- Software on CD ROMs or floppy
discs
How can you tell if your computer has a
virus? |
|
|
|
Some
common symptoms of virus infections are:
- Your computer suddenly slows
down. This can be more noticeable if your computer is connected
to a network.
- Your computer starts behaving
strangely. For example disc drive lights may begin to
flash.
- If you run an internal email
server, this may become overloaded and slow down. Your
data files such as Word or Excel may become corrupt or get
lost. Sometimes these popular programmes may display a
message telling you that your data files are not in their
correct format.
- Any unexpected changes in the
content of your files.
What can you do to stop computer
viruses spreading? |
|
|
- Ensure your computer
has the latest anti virus software installed and that the
virus definitions are up to date.
- Ensure that your anti
virus programme is actually switched on.
- When you use floppy discs
or CD ROMs from friends make sure you first scan them with
your anti virus programme.
