Trojan.Gen.2 Question

So last night my Norton did it's usual full system scan. When I checked today, I saw it dealt with 3 threat detections: one tracking cookies (the usual I only get from the full scans), and 2 others that are worrying me. Both are Trojan.Gen.2, and seemingly the same thing: one is ewluwtcas.class [Contained in] c:\users\{user}\appdata\locallow\sun\java\deployment\cache\6.0\43\67ba92b-29d64ef0 and it says Deleted. The other is essentially the same, just different class: rsbgrcqvwqbpsfenl.class [Contained in] c:\users\{user}\appdata\locallow\sun\java\deployment\cache\6.0\43\67ba92b-29d64ef0. Now it says this threat has been removed and no action required. But I can still locate the file in the folder, yet it was modified at the time the scan caught it. Should I delete the file, or has Norton fixed it and Java needs this file? Again, don't think I have any viruses, don't really do much on the computer besides play games on Steam or visit safe sites like Facebook or Amazon. Is this file suppose to be in the folder? Also maybe worth noting I haven't updated Java in a few months, and the file in question was created 8/12/13. Thank you!
