CPU and RAM being hogged?

No, you're looking in the wrong place. Don't click on the + sign next to run, just open the run folder in both paths.

Nothing in there

Nothing as in nothing or as in nothing bad? There has to be something in there.

Nothing there, unless ctfmon.exe and teatimer are viruses

ok and the complete username for that IWAM thing is
IWAM_COMPUTER-QGW14FCOMPUTER-QGW14F

edit: it also seems the registry cannot access the folder where the AppInit_DLLs thread is while the IWAM thing shows up in the taskmanager

something I also noticed while editing this
I used process explorer to check out the dllhost.exe which was running under the IWAM undername and it showed the .dll type name code 02D4B3F1-FD88-11D1-960D-00805FC79235, i'd seen this there before but thought nothing of it and didnt want to mess with it, but given that I've tried everything else, searching the registry for this brought up 2 results, I deleted them both and now searching for the appinit thread brings no results, and the problem doesnt show up in hijack this anymore, so I believe this is solved!

Glad to hear it.
