Ok, this is probably one of those things going around... to me, it's another reason to hate MS...(then again, even vim will do stupid things like this, out of the box on some machines).

Go in to MS Word and type :

Code:
=rand(5,10)
Then hit "Enter." (yes, those numbers can be bigger but we'll spare you -- it was initially suggested to me that it should be like (200,99); then again, simply rand() works too, which I think is even more disturbing)


Surprisingly enough, well... this shouldn't do anything malicious to your machine... I mean, it's just text, right?

*sigh*
