Whilst it's true that "any computer can get a virus" - if Wikia is sensible, then they probably aren't going to "get a virus" unless there's a really major bug in probably more than one system at the same time.

What's more likely is one of 3 things:
 * Wikia sold a bad ad that your AntiVirus flagged up (check Help:Bad advertisements)
 * Your antivirus issued a false-positive report (viruses are hard things to catch, most AVs have a system where they're fairly sure something looks like a virus, and so will flag it up to be safe)
 * You had a virus from somewhere else, and it happened to be injecting code in Wikia's site when your AV picked it up.

Normally, your system is ok, and unless you've changed anything, if you're running a modern Operating System (Windows Vista/7/8, Mac or Linux) - there's a lot of security that stops malicious programmes installing themselves. Being vigilant and not opening attachments in emails, or running programmes you don't trust will reduce your chance of getting a virus down to a very low level.

I'd recommend you reboot your computer and run a full AV check in safe mode to be sure though.
