“Windows XP exited public support on April 8, 2014, amid some panic on the part of corporations that had not yet purged their environments of the 2001 OS. Unless companies paid for custom support, their PCs running XP received no security updates after that date”
And we wonder why there are so many vulnerable computers on the internet. This would be one, of many, reasons.
If you’re running XP, you are not secure. You haven’t been for a long time.
