University Purchased Computers
OIT has a license with McAfee antivirus software for faculty and staff computers that have been purchased with University monies through a project and/or grant account number. Faculty and staff using DeSC computers do not need to take any action as the computers are configured to update their virus software and definitions from the Princeton servers.

- McAfee: How to schedule a scan and perform full system scans
OIT has implemented McAfee scheduled scans for all institutional Windows desktops used by faculty and staff.
- The scans will begin at 1:00 a.m. on Sunday, March 21, 2010, and will continue to scan computers weekly each Sunday. All Windows desktop computers with McAfee VirusScan are scheduled to participate. The decision to implement full system scanning was made due to the security issues involved with computers that do not scan, search and remove malware. Users who log into the computer during that time should experience minimal performance issues.
- McAfee software actively scans files that are opened, uploaded and downloaded with the most up-to-date virus definitions, yet sometimes a new virus can be downloaded before McAfee has a definition for it, or if the file is never opened after McAfee receives the corresponding update. Performing a full scan of a computer with up-to-date definitions is the only way malware can be detected and deleted once the computer has become infected.
