Re: Windows 7 may not be a refuge either
FWIW, this guy says even Windows 7 is infected with this behaviour if you've allowed "critical updates" since April
Interesting, but incomplete. I did find an article elsewhere that cited this:
This cites KB2952664 and possibly a couple of other updates (including an alternative KB posted for Windows 8). I just tried removing the KB from the machine I had set up with Windows 10 (and since reverted to Windows 7) and I ended up with some problems in the task scheduler. I wasn't too surprised.
The idea of a lot of hacking and slashing cited by the poster in Slashdot, however, doesn't yet give any details.
