moi, glad you are around to help..
I'm having to do some similar type stuff to my pc, hubby was searching for some car information and had a pop up down loader activate on his profile.
I logged off his account {limited} and onto mine {admin} so i could run all my AV, spy & malware scanners and clean out various things while I'm at it.
His account was clean but son's account had 2 baddies.
so your info & tips are adding to my knowledge base too.
