Did virus cleanup, now pictures won't pop up when mousing over links - What did I do?

[astro]

In Internet Explorer and Chrome when mousing over a list of sales on one of my online sale sites it would pop up a little preview pic of the purchased item. This was extremely handy for checking purchases.

I had a malware issue the other day and now after running several cleanup engines the virus is gone, but my picture pop up feature is also gone. It's dead in both chrome and IE so I don't think it's a browser specific issue.

Not sure that enabled it or what disabled it. Can I get it back?
