I opened my laptop to this today:
McAfee found 3 potentially unwanted programs:
I have quarantined all 3 of them.
are they dangerous? and should they be removed from my laptop?
Regarding the Artemis ones they are being investigated by the labs and until they give a verdict it wont be known what the result it.
The PUP - meaning Possibly Unwanted Program - is your choice, if you think you know what it is and it's harmless you can trust it.
