Virus protection can prevent a pc being attacked by viruses (program designed to erase data and corrupt files), worms (can forward virus through email to all contacts) and Trojans (hides by presenting itself as a harmless file).
Antivirus software spots intruders. It tries to trace viruses by spotting the virus signature. Therefore virus writers invent new viruses and design them so they change in appearance, size and have a different signature each time it infects another pc in an attempt to make anti virus software to spot it. However almost as soon as a new virus is written antivirus traces these new viruses and adds them to the database of information of viruses such as profiles and signatures of the virus. Updates are then made available to the users to block harmful viruses getting into their Pc. Some users either automatically or the user will be sent an email that an update is available.
The main defence against viruses is to subscribe to a reliable form of anti virus software, examples include McAfee and Norton. These perform regular scans, show harmful websites when using search engines, will block you from opening links or files which could damage your pc and delete the virus before it does any harm and stops the PC’s ability working at its full potential.

Firewalls are also a form of security. A firewall isn’t the same thing as anti-virus program, but to help protect your pc you need both a firewall and an antivirus program. Firewalls build a protective barrier around computers so that only authorised programs can access data on your pc. Firewalls work by checking information coming from the internet or a network and either blocks it or pass it through depending on whether it is safe and your firewall settings. A firewall can therefor prevent hackers or malicious software gaining access to your computer.
