You cannot say taht Firefox is "letting in viruses", but most likely it's text residing in the cache. It is harmless there. Firefox just displays the contents of Web sites, it doesn't run virus programs. And there is no other way to run that stuff when it's in the Firefox cache.
If you empty the cache using the Clear Private Data menu, it will disappear.
