Thanks for your response, Nergal, et al. I'm using Norton 360, and the Pro versions of SuperAntiSpyware and Malwarebytes. Online, I use Firefox and DuckDuckGo behind a VPN on a Windows 7 Professional home built confuser- er- computer. As I'm sure you know, CCleaner works in Safe Mode.
I spoke last week with the ever-young; the ever-lovely Mister Patel, the Norton Tech Support guy from Mumbai. He opined that I'd be best served by uninstalling everything except Norton 360. I remonstrated with him to no avail. I might mention that the first Norton product that I used was Ghost and that was in 1985. The only time that I called for help, Dr. Peter Norton, himself, answered the phone. A few years after that, Symantec bought Peter Norton Computing. Now, the good Mister Patel is of the mind that my home-built belongs to him; not me, and that do do anything without his sanction is an affront that he finds difficult to tolerate. We'll both live through it, I suspect.
