Statement of policy

All computer devices connected to WMUnet shall have anti-virus software installed and regular operating system updates performed.


This rule is designed to help prevent infection of Western Michigan University computers, networks, and technology systems by computer viruses and other malicious code. This rule is intended to help prevent damage to user applications, data, files, and hardware.


All  faculty, staff, students; as well as vendors, contractors, partners, collaborators and any others doing business or research with the University that involves access to University computers, networks and/or technology systems, will be subject to the provisions of this rule.  Any other parties, who use, work on, or provide services involving Western Michigan University computers, networks, and technology systems will also be subject to the provisions of this rule. 

Rule statements

  • All computer devices connected to the Western Michigan University network or networked resources shall have anti-virus software installed and configured so that the virus definition files are current, routinely and automatically updated. The anti-virus software must be actively running on these devices.
  • All computers owned by the University and used by faculty and staff must have the most recent version of anti-virus provided by the University installed.
  • All PC's are to be configured such that they schedule regular operating system updates as provided by the vendor (Windows updates.
  • Macintosh systems are to be configured to schedule regular updates from the software manufacturer (Apple security updates).
  • All files on computer devices will be scanned periodically for viruses. 
  • If deemed necessary to prevent propagation to other networked devices or detrimental effects to the network or data, an infected computer device may be disconnected from the University network until the infection has been removed. 
  • Exceptions to this rule may be allowed if a computer device cannot have anti-virus software installed.  Possible examples of this would be vendor-controlled systems, or devices where anti-virus software has not yet been developed.   In these cases, plan must develop to protect the device from infection.
  • An exception may be granted if an infected computer device is discovered that performs a critical function and may not be immediately taken off-line without seriously impairing some critical business function.  Under those circumstances, a plan will be developed to allow the computer device to be taken off-line and the infection purged while protecting the function of the device.

Anti-virus software

The University provides Symantec Endpoint Security anti-virus/anti-malware software to faculty and staff members free of charge.  For students, MicroSoft Security Essentials is available for the Windows environment and ClamXav is available for the MacOS environment.  Both are available as free downloads. Additional information.


  • When infected computers are discovered through routine scanning proccesses, or reported to the Office of Information Technology, managers, or owners, will be given until 5 p.m. that day to correct the problem or remove the computer from the network. Information technology will remove network access if the problem has not been corrected, and reserves the right to remove any infected computer at any time should security of University data or networks be compromised.
  • Any person found to have violated this rule will be subject to appropriate disciplinary action as defined by current University policy, student code of conduct,  and/or collective bargaining agreements.  This rule will not supersede any Western Michigan University developed policies but may introduce more stringent requirements than the University policy.

Note: These rules and requirements may be amended at any time by the chief information officer of Western Michigan University consistent with current collective bargaining agreements, University policies, and applicable law.  Changes will be reviewed by appropriate University entities prior to posting.
