Virus Checking Software is often referred to as an anti-virus because the software first checks the system for the viruses and is able to get rid of those viruses. It also detects when viruses are trying to install themselves on a computer and prevents this process from completion by deleting the files, and not allowing them access to change settings etc. Virus Checking Software will run all the time on a computer in the background in search for activity which may cause the computer harm. This software will also need to be updated regularly because it will download new information which has been found about viruses and where to look etc. Full scans of the computer, or quick scans, can be started with a click of a button. These scans will look out for malicious content stored on the computers and systems. Systems and data are much more secure when Virus Checking Software is installed because it means that no viruses can steal information from the system. All of the data on the system is safe from attacks. Some Virus Checking Software will also come with firewalls, such as Symantec.
