Potentially malicious ads on Deckbox?

Hi!

Twice now I've gotten redirects from Deckbox for a "safewinodws" which is disguised as McAffee total security. It doesn't happen on an other website. It's a redirect, so it brings up a new page. This only happens on Deckbox, and (I think) whenever I click on something. I'm not sure if there's some advertiser who is serving up malicious ads which secretly take up the whole screen, but I think it's something that might need to be looked at.
