alrighty then, sounds indeed like you have followed a logical 1st step of action..

now let's try a 2nd step...download and install both AdAwareSE and SpyBot search and destroy, install them, update them (as a note, w/spybot I suggest one of the Safer Networking servers to download from), then run them...I'll bet they find something on your machine...if they do, try running LW again and see if your Java is still acting up..if that fails, post back and we'll try a HijackThis scan and see what it turns up...
