Way too much marketing of Microsoft Word and Microsoft Edge

Since I have purchased my Dell Inspiron 16 plus I have had nothing but trouble or annoying marketing efforts. First the touch pad stopped working. I had it repaired three or four times (lost count), then demanded a new laptop (to Dell's credit they sent me a new one - same model), within a month the touch pad stopped working - I now use a mouse - I give up.

I'm a google user and every time I open my computer Microsoft Edge opens up - then I have to close it to get to Google. Microsoft teams keeps popping up and it is tricky to close it - I use zoom. McAfee  Security constantly makes me click to close their marketing pop-ups - I don't want McAfee. I don't want Microsoft Edge and I don't want McAfee.  I'll put up with the defective touch pad, but the marketing is driving me crazy and taking time away from my work. If it doesn't stop soon I'm just going to throw this laptop in the trash and get myself a MAC. Can somebody tell me how to make it stop?
