[Mediawiki-l] HTML:Iframe-inf virus?

I got an email from someone accessing my wiki:

http://against-the-day.pynchonwiki.com/wiki/index.php?title=Main_Page

I'm using v 1.9.3

Here's the message I received:

I get a message from Avast anti-virus that the page is infected with : HTML:Iframe-inf. I have contacted Avast who says this is not a false positive. You can Google virus name--it seems that this infection is fairly common. Please let me know if the infection is real--I would like to use the wiki.

Any idea of what I should do to address this?

Thanks! Tim
