Ongoing Virus - Gen 2

Every scan for several weeks Norton makes on my Mac, I get the following problem:  Event  Trojan.Gen.2   Result  Virus detected. Details:  users/"my name"/caches/java/cache/6.0/58/4425dafa1a2a280a.  It appears to locate it but does not quarantine it or eliminate it.  

 

I had spam sent to all my contacts last week but not sure if this trojan is the culprit.  I tried to run Power Eraser but only get a text block saying san't open in DOS mode so it must not operate with my Mac OS.   Any advice?
