I don't think it has anything to do with home products so have moved this provisionally to Encryption ePO Managed.
Endpoint Encryption Agent isn't part of the home product at all.
He says he already tried that. Those entries don't look like consumer product to me.
Donjuane, if all else fails you could do it the long way.....signed in as an Administrator-level user of course.....
You could go the normal way - looking for McAfee folders in Windows Explorer and delete them from there. Or do the registry method:
The regedit procedure can be done offline if you wish.
Go to Start/Run and enter regedit and click OK.
A page should open with the top left hand corner looking something like this:
if for some reason it's expanded, collapse it and then highlight My Computer (Computer in Vista/Windows 7/8).
Go to File tab and click "Export" and send all of the registry to your desktop. This is in case something goes wrong. It can then be rebuilt by simply right-clicking that desktop item and selecting Merge.
Now click the Edit tab and then "Find". Enter "McAfee" (minus the "") then click "Find next" (or hit the enter key).
Whatever is found, right-click and delete.
Hit your F3 key for the next instance and keep going until all entries are gone. It can take a long time if a lot of McAfee components were oroginally installed and the MCPR removal tool (Useful Links at top of this page) didn't work for some reason.
If one says it can't be deleted this is where it gets complicated. You have to then find which key on the left column pertains to it and right-click/Properties/Permissions and give yourself permission.
