When it comes to viruses, companies such as McAfee and Symantec do what they can to stay on top of the new releases. Unfortunately, there is a lag time between when a virus first appears and when the companies release a new virus definition to block the virus. What's more, there's usually an even greater lag time before users download the definitions.
