Manually Removing McAfee VirusScan

The instructions in this document will guide you through deleting specific items from your computer. If you are instructed to delete an item that you cannot find, skip that step and continue with the next step. Some steps may not be applicable to your installation of McAfee VirusScan 5.0x.
