What does an anti-virus software do to protect the computer from cyber threats?

Anti-virus software is used to detect and remove malicious software ( malware), which is used by hackers to infiltrate computers and servers to provide a form of back-door access or programmed for malicious intent. This could include turning the computer into part of a bot network designed to ‘attack’ other websites or computer systems.

These days, anti-virus software are also capable of detecting spyware, a type of malware installed on computers to collect information about users without their knowledge. Spywares can be programmed to steal your credit card information, passwords or other sensitive data and use them against your knowledge.

So make use of the anti-virus software to detect and eradicate such threats. Use anti-virus software to scan internet downloads, external discs and drives, and schedule periodic scans of your whole computer. To be effective, the anti-virus software must be configured to update its signature databases automatically.


  1. My son will be joining the school in 2013. I want to know if the LD comes with anti-virus software?

    I have a commercial anti-virus software license with online activity monitoring feature. Should I install it on the LD?

  2. Hi There,

    If you had bought the LD from NCS, it will come with free basic anti-virus provided by Sophos. If you want to install another kind of AV, we suggest you uninstall Sophos before installing it with your own copy.

    While we are not against parents or students who want to install AV software that provides better protection, do note if you are going to use the helpdesk support service in school, they might need to call you for access when troubleshooting certain problems that needs to circumvent the AV you installed.
