Problem NPE

Bizarre issue with Norton Power Eraser. I have Two Norton Power Eraser's. Both are legitimate, one I download ages back AND I have a second one that came built in to Norton 360  Premier Edition (or whatever, its exact name escapes me at this point). Anyway, the other day I clicked play on a vid on the Internet (my fault for going outside the outright (or at  least by comparison) safe vid viewing of youtube) and got a windows update prompt (the legitimate type, the shield update sitting on the shutdown button).

Knew it was fake to an extent, but unsure what to do and stupidly not thinking I shut down.

Moment it booted up I ran a Full scan. After that I ran NPE from the NPE shortcut on my desktop after full scan was done. Nothing, no threats.

Now things get interesting. I would print screen, BUT I don't want the risk of the (likely) virus to spread to my laptop, so I'll explain. With no threats found I dismissed  the risk of a threat, went net surfing for some stuff, fine. When I finished web surfing I ran ANOTHER NPE scan, this time from the one built in to Norton 360  Premier. THAT NPE scan found 11 threats. They were:


naveng.sys (in the list a few times)

navex15.sys (again, in the list a few times)

and: idsvix86.

Clicked remove threats, they fail to remove.  After the fail to remove I retry, using the same NPE inside Norton 360  Premier, now it loops at "Norton Power Eraser has successfully restored Internet or Synmatec server connection" etc. etc. Occasionally the loop gets broken and you get the serach results. Same 11 threats. Same fail to remove, loop cycle starts again. Fed up with the continually looping, I decide to google research the 11 none removing threats, are they components of Norton? (they seem to be) If they are does that mean my Norton is infected/compromised
