Interesting. I almost clicked on the same file (I think) but Firefox itself warned me not to proceed. Glad I paid attention. I got the ransomware virus a few years ago thanks to McAfee, which demanded that I disable my old virus checker before proceeding with installation. That gave the virus, which had been suppressed, free reign to install itself. I had to reformat and reinstall everything. It’s a pain in the butt. Sorry you are having such difficulty.
Thank you. I was worn to a frazzle Thursday--totally exhausted. It was an awful day, but I was happy that I had accomplished a couple of things that needed doing. I was just watching some old movies and a couple tabs just appeared. I'm so used to just closing them, but I'm afraid I may have clicked on one reflexively. Too bad my anti-virus wasn't powerful enough to just block or neutralize it. I realize now a scan before logging off would probably have caught it.
Still, the old thing was on the way out. It's just that it was still working so perfectly.
Thrsday night I was in paradise; the next morning I was expelled.
