Running Malwarebytes Premium and MSE. Yesterday got in 'debate' with friend about whitetail deer. Both of us are avid outdoors people, or used to be. I had never seen a whitetail deer any place but Texas and I think I've hiked, ridden or skied over most hills in the West and most certainly in New Mexico, the area of the debate. Found a couple of answers and a forum discussing this very thing, read a thread and as I tried to click off of it, got a popup that froze my browser, Firefox. Immediately scanned with both Malwarebytes and MSE and found nothing. Only way to close browser was to reboot, which I did. Popup still there and browser still frozen and totally non responsive. Opened Edge to try to get info on issue whereupon the popup disappeared on its own, I was able to close Firefox and reopen with the popup gone. Scanned again and cleaned. Nothing. No issues the last 24 hours and more scans produced nothing. These bad guys are pretty stupid I think. Googling the number to call (1888-610-5078) it seems some callers have been directed to other numbers based on the error codes in the popup. I don't cruise bad sites and stay pretty much on known turf, until debates like ours come up, or I have curiosity about something. Even so, looks like we're all vulnerable. Incidentally, I lost the argument about the deer. They ARE in New Mexico, and most of the western states though I've never seen one neither on the hoof nor dead, and I can't count the numbers of deer I've put on the table or seen on the hoof, and I hunted them for food for my family for several years and since I was a kid.
