This issue started a few weeks ago. Frequently, when I switch from one page to another, I get a pop-up page from some unrelated business or form. I have started to fill out an order form for a trusted business only to find out I am filling out another company's form instead. My page gets hijacked in this manner several times a day. It's not only annoying, but a security issue. One moving company keeps popping up. I am not moving, or even thinking about moving, but I keep getting this company's home page when trying to access other venues. I don't know if this is related, but I installed Duck Duck Go a while back to avoid Google trackers. A few weeks ago I found that Duck Duck was no longer my preferred search engine and put it back as preferred. Whether coincidence or not, my problems began about that time. Please help.
