  trojan horse  
when i upen my task manger and end its process it seems to make my slow computer faster. sometimes takes several trys to stop it for good.
It belongs to McAffee
Its is ran by Mcafee,It does take up alot of memory and VM.It will not harm you to delete,i also delete as it may free up some space and give you some speed.Over all i would not suggest even getting mcafee because it just sucks the speed away from your comp.
My PC restarts unexpectedly, when looked for the reason on the system events, its this process that initiates the reboot.
mcupdmgr uses 30-57% CPU for days on end. If this is supposed to be doing updates, it never seems to exit and severely negatively impacts my machine's resources.
