General Advice for VirusScan

General Advice/Hints and Tips


Windows User Account Control on Windows Vista can cause intermittent rights issues with VirusScan which are difficult to trouble shoot. If you do experience odd behaviour then disabling UAC is often a good first step for troubleshooting. These issues are frequently fixed in patch releases. Windows 7, and later versions of Windows, has a much more granular and better approach and as such there are less occasions when UAC IS a problem.

Installing New Software

When installing new software it is generally recommended that you temporarily disable McAfee On-Access Scan. To do this you need to:

  1. Open the VirusScan Console
  2. Double-click on Access Protection
  3. Untick Enable Access Protection

You will now be able to disable On-Access Scan in the usual VirusScan 8.0i way by right-clicking on the VirusScan icon in the system tray and choosing Disable On-Access Scan.

Note: Don't forget to re-enable it when you have finished installing and rebooted the machine.

Upgrading Windows Systems

You need to uninstall your current version of VirusScan before you upgrade a Windows system or else you will probably have problems.

Update/Upgrade Problems

If the system stops automatically updating there are 2 actions to do first

  1. Right click the VirusScan shield and select Update Now
    If this fails proceed to step 2
  2. Download the latest SuperDat (from
    The super dat is around 100 megabytes in size, if you are on slower connections or have limited connectivity you may need to seek help from your local computer officer or the Service Desk.

Advanced trouble shooting beings by looking in the update task log. This can be found by right clicking the VirusScan shield and selecting VirusScan Console. In the list of Tasks, Automatic update should be listed, showing when it last succeeded or failed. Select this, right click and then select View Log, or View Activity Log depending on your version.

Re-Install VirusScan

As a last resort you mey need to perform a re-install of McAfee VirusScan by using the Add/Remove Programs/Features icon in the Windows Control Panel.

You should also remove references to McAfee from the File System (in C:ProgramFiles and in your user profile) and in the Registry, this is an advanced operation, if you are unsure contact your local computer officer or the Service Desk.
