Use anti-virus

Anti-virus software protects your computer from software viruses, and prevents you from accidentally passing them to people you work with.

Computer viruses get into computers:

  • via email
  • by clicking on infected links (on social media sites or compromised websites)
  • from infection by other people's compromised computers
  • through the network, especially if you have not kept your software up to date

Anti-virus software doesn't only protect your computer from viruses. It also prevents you from being the person who transmits them to others.

New computer viruses are being created all the time. It is important to keep your anti-virus software up to date so that it is able to recognise them.

What is malware?

The term malware comes from blending the words malicious and software together.

Malware includes:

Virus (Viruses)
The generic term for any software that self replicates. Computer viruses these days do more than self-replicate. They almost always are designed to do some kind of harm.
Devices or software designed record everything you type. Their goal is your usernames and passwords.
Once installed on your computers, it detects what you do and transmits this to hackers or cyber criminals. It can be similar in operation to software keyloggers.
Trojan horses
Malicious software that lurks inside software that appears nice or useful.
Malware that, once installed, provides an easy way for hackers to get back into your computer.
Malware that probes the network for vulnerabilities seeking to replicate and spread.


What does anti-virus software do?

Anti-virus software scans a computer's memory and disk drives for viruses. If a virus is found, the anti-virus software will notify the user. It can then clean, delete, or quarantine any infected files.
