8. Software protection
Anti-virus software
This specialised software is used to detect viruses and to limit their damage by removing them.
The software tries to detect viruses before they can get access to your computer. If a virus is detected trying to get through the firewall, the software will give an alert and ask how you want to respond.
It is usually set up to scan your computer on a regular basis and to check every file being opened before it is allowed to run.
Anti-virus software is normally set up to check online for an update every few days or so because there are so many new viruses appearing every day.
