A definition file contains a list of virus signatures that needs to get updated regularly so all new viruses can be detected. When your anti-virus software scans your computer for viruses, it checks against the definition file and if a match is found, that means a virus has been detected on your system. Without regularly updating definition files, the anti-virus software is ineffective since it is not protecting your computer from new viruses.
McAfee VirusScan is available to all registered students, staff and faculty at no cost through the CCS software distribution site.
Once you have installed McAfee, follow these steps on a weekly basis to update the definition files for McAfee VirusScan:
- Right click on the VirusScan On Access-Scan icon in your system tray located at the bottom right hand corner of your screen and click Update Now. If it's not there, you have not installed McAfee VirusScan or it has been disabled.
- Your computer will download and install the update and will auto close the screen after 30 seconds.
- To confirm if the update was successful, right click on the VirusScan On Access-Scan icon in your system tray and click About VirusScan Enterprise. Make sure the Created On date is current.
Please note: update your definition files regularly since new definitions are generally released once a week. This will ensure your computer is protected against new computer virus threats.
