McAfee Anti-Virus 8.8i Guide


About VirusScan / Installation Notes

  • McAfee's VirusScan Enterprise 8.8i is a commercial anti-virus software product that has been site licensed for distribution to the SF State campus community. The installation and use of this software is restricted to current SF State faculty, staff and students.
  • Starting with version 8.8i, the university license for McAfee VirusScan also includes an anti-malware detection tool.
  • VirusScan Enterprise 8.8i has been configured for home use. This configuration may not be appropriate for LAN servers or managed LAN workstations. System administrators should download and read the VirusScan 8.8i Product Guide.
  • For security reasons you should have the most recent Windows Service Pack installed even though VirusScan Enterprise 8.8i can run under an earlier service pack.
  • McAfee's retail VirusScan package uses different, usually higher, version numbering than the enterprise package. Only the interface is different, not the ability to protect your computer.

VirusScan Enterprise 8.8i Installation Guide

Learning how VirusScan works and what its settings mean will make it a more useful tool to fight viruses.  You need to have Adobe Acrobat Reader installed to read these guides.


Additional Actions

ITS recommends you run a complete scan of your hard drive at least once a month.


To be most effective against active viruses you should boot your computer into Safe Mode prior to running the complete scan of your hard drive.


To boot into Safe Mode and Perform a Complete Scan:

  1. Restart your computer and hold down the F8 key until the Start Up Options screen appears
  2. Use the arrow keys to select Safe Mode when prompted at the bootup menu
  3. Click on Start on the Windows taskbar then select All Programs > McAfee > VirusScan On-Demand Scan
  4. In the On-Demand Scan Properties window click on the Start button
  5. If the scan detects a virus you should follow the Virus Removal Instructions
  6. When your hard disk has been scanned the window will close and you should reboot your system



VirusScan has three features that can potentially conflict with other applications:

  • Access Protection:  There are several types of programs used by viruses that can be restricted by VirusScan.  The default settings only allows specific mail clients to send mail.  This helps stop viruses with built-in mail capabilities from spreading.  If you use a very unusual mail client it may be blocked from sending mail.  Read the section on Access Protection in the VirusScan Product Guide for instructions on adding your mail client to the list of allowed mail clients.
  • Buffer Overflow Protection:  Buffer overflow attacks use a particular type of programming error in Windows or specific applications (e.g., Internet Explorer).  Some software firewalls also provide buffer overflow protection.  If both the firewall software and VirusScan are protecting against buffer overflow attacks at the same time they will conflict with each other.  If you have a firewall or other application that provides buffer overflow protection then you must disable it in either VirusScan or the other application. The firewall built into Windows XP, Vista, and 7 does not provide buffer overflow protection and will not cause a conflict.  If you use any other software firewall you should read its manual carefully to determine if it provides buffer overflow protection or not.  Read the Buffer Overflow section in the VirusScan Product Guide for instructions on disabling buffer overflow protection.
  • Multiple Real-time Scanners: McAfee VirusScan 8.8i is a real-time protection program. Running more than one real-time protection program silmultaniously can cause many problems. However, it is a good idea to install secondary, scan only, malware removal tools. For university owned computers, ITS recommends Spybot Search and Destroy. For personal computers, ITS recommends Malwarebytes. It is illegal to install Malwarebytes on university owned computers without purchasing it. 


If you encounter errors installing VirusScan 8.8i, first remove it by using the Add/Remove programs icon in the Control Panel and then reinstall VirusScan 8.8i. If this does not work do the following:

  1. Remove VirusScan using the Add/Remove programs/Programs and Features icon in the Control Panel.
  2. Use Windows Explorer to locate and delete the C:\Program Files\Network Associates folder and the C:\Program Files\Common Files\Network Associates folder.
  3. Reinstall VirusScan 8.8i using the instructions provided in this document.


If you still cannot install VirusScan, contact ITS's Service Desk at 415-338-1420,, or bring your computer to ADM 110 during business hours.
