1 The Bing search engine has recently invaded my computer and I am having a hell of a time getting rid of it. It adds geegaws to and opens new tabs in my browser, and even opens whole new pages, all when I am not, and have not indicated that I am intending to search for anything. A pox on Microsoft and all its houses.

2 Yeah; I hate Bing at this point too and for the same reasons. Bing is my default search engine because I bought this new laptop that promotes Microsoft and won't let you download programs not related to Microsoft. I have to go online and open Duckduck Go. Bing gives you a Bing address for everything too, and it's very long and complicated and I don't want it when I'm writing something. And, as you say, it's full of ads.
My laptop won't allow you to download non-Microsoft programs. It has what they call S-mode and it blocks them. I can't, for instance, use Firefox as my browser. I know how to take the computer out of S-mode but I did it to the first one I bought and shortly after that I had an error - the little pointer disappeared and never came back despite my efforts to trouble shoot it. It is said to be a common problem with this type of computer (Lenovo) but it happened right after I took the machine out of s-mode, which makes me think it was a kill switch they put on it to eliminate the cursor if you dumped the S-mode. If they had made it obvious they could be sued for restraint of trade but by being sneaky they can claim plausible deniability. At any rate I took the machine back to Best Buy and they exchanged it for me - but only exchanged, I couldn't get a new gadget. So I'm stuck with S-Mode and have to use Internet Explorer and other stuff or risk getting burned again. 
Microsoft and all it's products suck.
