Exploit:Java/CVE-2009-3867.QI

I have Windows Vista home edition, 64 bit and IE 9; I also use firefox.  I had a lot of registry errors which usually tells me that my system has been infected with some kind of malware.  I ran Norton Power Eraser and it said my system was clean; I ran Microsoft malicious software removal tool and it also said my system is clean.  However, Microsoft safety scanner caught but only "partially removed" Exploit:Java/CVE=2--0=3968.QI.  It said the threat was severe.  Would Norton Power Eraser Beta pick this up?
