Frequently causes errors when switching between users. If you want McAfee you gotta have McSvHost too. Shouldn't use more than 20-25kb of memory, which isn't much.

It's a file related to McAfee Internet Security.

It duplicates itself in your Firewall allowed apps whenever you try to remove it, even after the software is supposed to be removed from your system. Very weird.

Best practices for resolving McSvHost issues

A clean and tidy computer is the key requirement for avoiding problems with McSvHost. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command.
