It used to be enough to update your antivirus software once a month or so. Then it became once a week. Now sometimes it seems that daily, or even multiple times a day may be necessary depending on how busy the malware authors are.
To configure how and when McAfee Internet Security Suite 2005 gets updated, select the Updates link at the upper right of the main Security Center console and click the Configure button.
There are four options available:
- Install the updates automatically and let me know when the product is updated
- Download the updates automatically and notify me when they are ready to be installed
- Notify me before downloading any updates
- Disable automatic updating and let me manually check for updates
I highly recommend that you leave the first option selected. There have been rare occasions with rare situations where an antivirus update may cause conflicts with the system and create problems, but they are rare enough that most users, particularly home users, should just let the software update automatically so that the antivirus protection is maintained without any help from the user.
