The Virus Definitions sensor in Norton System Doctor has determined that your Virus Definitions (the files that contain information about current viruses and how to detect them) are about to expire. To protect your computer from viruses, choose Update Now for free updates provided by Symantec.
This message may appear the first time you open Norton Utilities because this alarm is set by default to go off when the virus definitions are more than 35 days old. Select Update Now to receive definitions that have been updated since the box you purchased was created.
