Yikes, here's something to watch out for!

Apparently, if you're seeing advertisements in Wikipedia, then you have malware.  If this is your work laptop, please get it to IT as soon as possible so that we can clean it up.....if it's your own machine at home, then I recomend the utility MalwareBytes, it's free, easy to use, and very effective at cleaning out the more stubborn forms of malware out there.
