Many Internet users are unaware that most anti-virus programs quickly become out of date as new and more sophisticated viruses enter the world of cyber-space everyday.
Anti-virus software must be consistently updated in order to remain effective. In some cases it is necessary to buy an entirely new program to help keep your computer virus free.
Most anti-virus programs allow you to update the original program by downloading the newest and most recent updates to their virus protection system. These updates can then provide protection for your computer against new strands of viruses waiting to infect your computer.
