The largest threat to a personal computer is by far the possibility of receiving a virus. In this modern age of computer safety and internet security, there are measurements that the home pc owner can take to ensure that they do not become victim to this. Norton, is a program that monitors and eradicates this danger. Viruses are essentially programs designed to destroy or manipulate safe working programs on your pc. Most computers have firewalls built within the programs and operating system (os) that keep these unrecognized programs out and as you have probably noticed have the popups that say, “are you sure?” Well irritating or not, that is your firewall, internet, and pc security at work. However, these are merely precautionary tools and an antivirus program, like Norton, is recommended as they are designed to clean up any files or programs that causes damage to your pc.
