| Better off with it than without it, as it will scan for malevolent controls and viruses.

 | This file runs as a service and uses lots of processor time even when the active virus scan is disabled. It's not worth it.

| This file is required by McAfee to run live, real time AV shiedling - as opposed to running periodic or scheduled manually. TuneUp Utilities 2004 tags mcshield.exe as the only file - on a brand new high-end XP box - which uses unusually high resources.

| This is part of McAfee Virus Scan. Mcshield.exe constantly monitors your computer's running processes, accessed file and registry to detect virus activity. It is one of the core components to the virus protection offered by the McAfee virus scanning software and should not be stopped. If it is stopped your computer will not be protected from viruses. Mcshield.exe is flagged as a system process and does not appear to be a security risk. However, removing McAfee Shield may adversly impact your system.

| On my machine at work. It can lock up your machine for 20 to 30 seconds at a time several times an hour. I wouldn't recommend it.
