Virus Checking Software can also be referred to as Anti-virus software in which the main aim is to protect a computer from any potenital threats. Virus Checking Software tends to be mroe of a software that the user is going to need on their PC so that they can have the ability to check for any viruses that may be on their computer or even on the organisations/users network. 

 

The reason why this would protect data is that it will check to see if any viruses are on that piece of data. This then means that the data is going to be protected because of the amount of virus software that will be on the data, this also implies that the data is important to the organisation.
