Had Limewire about a month, was working fine (except for the usual corrupt files etc) until a few days ago. Now, when I click on "search," I can see it searching, but the only things appearing in my window are files i downloaded a few days ago. Nothing new with the option of downloading is appearing in the view. I tried clicking on every button I could, with no results. Do have to say my virus-watcher detected a virus and locked it away. Could LW have been affected? Or am I missing something about how-to-view search results? Help!

It's quite possible that your anti-virus has just isolated the infected file without repairing it.
In this case the file would not be available to the program.
A reinstall of LW should fix things, but before then ENSURE that your anti-virus is up to date and run a full scan.
