What is antivirus software?
Antivirus software is a computer program which is usually installed on your computer and helps to detect, or prevent and or take action to remove malicious software programs, such as Viruses, Trojans and Worms. You can help protect your computer against viruses by using antivirus software.
Computer viruses are software programs that are deliberately designed to have an undesirable effect on computer operation such as delete data, record or corrupt data and also to spread themselves to other computers and throughout the Internet or your local network.
Antivirus should have an auto update feature and your antivirus software should be updated regularly using this to help prevent the most of the current viruses.
