PC users buy virus software all the time, but few users ever bother to renew subscriptions or update virus protection. They have outdated programs, and this is often the entry point for new viruses that infect their systems.
Virus definitions have to be updated. PC users may think that it is some sort of scam, but it is not. Even free virus protection programs require updates of the virus definitions. This is often the only way that the program can really be effective.
A new virus that surfaces may not be recognized by an outdated program at all. This is why it is important to do the updates on a regular basis. Virus, spyware, and malware is changing all the time. The same virus that attacked your system several years ago will not be the same virus that attacks today.
Virus protection programs are only good at stopping attacks when they are up to date. The majority of the software programs allow people to connect to servers. Once they connect they can update their accounts.
People that stick to their outdated virus protection programs will find themselves at risk. They will become more vulnerable to attacks from new virus threats.
