polonus, so if my results using the “software removal tool” you suggested for me to use is “no programs found” then I should NOT have any concerns about what you referred to previously regarding a “sneaky browser hijacker” (a pop-up ads virus downloader)" as reported by the Zulu Zscaler scan report: -ak.imgfarm.com pop-up ads, RIGHT?
So then I’m “clean” in that regard?
Your more knowledgeable in the area of computer security than I’d ever even dream of knowing even if I had another entire lifetime a lot of which I have no idea what your talking about unfortunately, but I certainly do appreciate the help concerning what doesn’t go right over my head. 
There is so much on computer security it is overwhelming for me as to what is the best way to go. Maybe I’ll try the “uMatrix” extension as it’s got good reviews.
