Good anti-virus strategies and the use of defensible virus software is integral to protect your computer these days. Viruses have developed over time and are now more critical than ever.
They have built-in elegance, layered on lessons learned, and the code was written by experienced programmers' bad intentions over the years. The development of viruses and virus protection are leapfrog events.
What I mean is that a virus is created and deployed. Once discovered, powerful business antivirus companies such as Symantec, Norton, or McAfee defenses to build the new virus and extend these updates to these clients using their software.

Companies such as Microsoft and Apple also regularly create patches and update plug vulnerabilities found to put into their operating systems and then deploy these to their customers. As long as there are people and entities out there with the mal-intent, this cycle will continue.
Always keep the anti-virus software that you have purchased to date as possible. When updates are available, implement as soon as possible.
The next thing to understand is that there is no anti-virus out there today that can guard you against all. This means that to further reduce the vulnerability of your system – and you can never be secure.
When security updates are available, know that they are offered because new system vulnerabilities were discovered and that you implement an update was put there to protect your system against these different vulnerabilities found.
