When you purchase a new PC, you wouldn’t dream of connecting to the Internet without having an antivirus tool in place. Because it’s fairly common knowledge that the pace of growth and infection of viruses and attacks that affect personal computers is increasing rapidly and they can do serious damage. PC viruses and malware are often looking for personal information, like credit card data, that can be used for criminal and fraudulent activities.
To counteract the PC infection and theft that viruses and malware can cause, anti-virus tools have a sophisticated knowledge base of active threats. And they continuously look out for computers that have out-of-date antivirus software so they can update it automatically to protect PC owners and their computers from new threats as they are discovered.
