Have you sent this to Special:Contact? There are 3 situations that are likely:
 * Wikia has mis-sold an ad which contains malicious software
 * You have a virus on your computer that is changing the ads on Wikia
 * McCafe is giving a false positive

In case 1, Wikia needs to deal with this quickly. In cases 2 and 3 they can let you know and you can clean your system.

IMO, I'm guessing it's #3, that site has no information that would draw the conclusion that there's a malicious host on that IP, apart from them telling you that.
