Thanks Phil but I did do a couple of google searches and that's where I started to get bogged down. There was some fairly fancy (for me) registry surgery involved that I didn't feel comfortable with. Fortunately I found a program tonight (gotta love google) called "Super Ad Blocker" that gives a 15 day free trial that seems to have managed to strip the
troublesome pesky
thing out
, along with a couple of other fairly pungent ones I'd heard about but didn't know I'd contracted.
