Today, I had the most peculiar experience. A (female, and pregnant, but that has no importance at all for this story) cousin of mine complained on Facebook about a virus infection on her Windows machine (I assume Vista, but I actually didn't bother to ask). Locked out by one of these ransom viruses. Worst part is that she did have an up-to-date antivirus sponsored by the Bank where here partner works.
Pohl's law: Nothing is so good that somebody, somewhere, will not hate it.
