Note: Most people will NOT have this problem and can install safely and simply by following the instructions at BU’s McAfee VirusScan download site. Please try following those instructions first: they are easier and faster.

If you have had trouble…please try Solution One first.

Here is Solution Two:

Manual Uninstall:

There is a way to uninstall VirusScan from the command line. It goes like this.

1. Make sure you have a VirusScan install file already downloaded on to your computer somewhere so that when the time comes to reinstall, that install file is ready to go. ( is one place to get this from [BU login required])

2. Unplug your computer from the network since we are about to disable (what is left of) VirusScan and it’s best not to be connected without that protection.

3. Go to the Start menu and choose Run. Type (or copy and paste) the following and press Enter:

msiexec.exe /x{5DF3D1BB-894E-4DCD-8275-159AC9829B43}

This uses the Microsoft Installer service to uninstall VirusScan 80i. You should be asked if you are sure you want to uninstall this product. Click “Yes“. Answer any other questons you might see.

4. Reboot the computer.

5. In Windows, go to program filesnetwork associates and delete any subfolders you see left there (assuming you are running no other Network Associates products)

6. Re-install VirusScan from the file you found or downloaded in step 1.

6+ Near the end of the install you will be asked if you want to Update Now. That is your cue to plug the computer back into the network so it can find the updates.

7. Let updates happen. Voila!

What if that did not work?

If this still did not solve the problem for you — if it failed anywhere along the way — please contact the IT Help Center. It is possible that you have existing spyware or other malware on your computer that is blocking the install. We can help.

Meanwhile, please be careful — you may not have any anti-virus protection on your computer, so you should avoid connecting to the network until the problem is solved.
