Are you talking about Windows updates?
No, AFAIK this only affects you if you use any systems that run Unix, Linux, or Mac OSX.
Star Trek posts these warnings every so often, but don't worry too much.
It is important to know, though, if it does affect you, so thanks, Star Trek.
I am sure Alex would have warned us if it affected the majority of users here.
