I've never seen that issue, but I would say that McAfee is notoriously bad with its retail consumer offerings when it comes to virus/PC protection and messing up things on PCs. I gave up on McAfee two years ago and went to Kaspersky, which is a dream. Runs smaller, cleaner and virtually trouble free.
Are you using IE as your browser? Which version? Make sure you're using the latest (9.x). That's the one Microsoft keeps patched these days.
Also, are you keeping your Windows OS patched and up-to-date?
You may want to try installing Google Chrome as a separate browser and use your Google toolbar on that only. I don't use Yahoo or Bing - I don't care for Bing and have never needed Yahoo with Google toolbar on board. You shouldn't need to login to your Google account for the toolbar to work.
OK, let me see if I can clarify - when I said "runs down the back of the stove", that's me interpreting the guy who is working on it. What I can confirm is that the wire starts at tab 4 on the control panel, goes to another plastic connect "thingy" (my technical term for it), and then a wire comes out of the "thingy" and we don't know what that wire connects to (that connection is what I'm calling a "termination point" - meaning the wire connects to something and terminates at that point). I'm thinking the broiler connection is probably right.
The thumbnails Chat has provided are looking helpful. I was trying to find a copy of that wiring mini manual but couldn't locate it anywhere.
Good lord . . . my thread topic title should have included the word "connects", not "coonts". "Coonts" sounds like something my mother would wash my mouth out with soap for saying. Suffice to say, I can't find an edit button, or I'd correct my own seeming potty-finger accident before anyone sees it. Good thing it's still only 2012. If it were already 2013, I'd say I was doomed for another year.
