Trojan

HI
While my main antimalware software is CIS, I do from time to time scan with others. Two days ago an Eset online scan detected the following Trojan > “Java/Exploit CVE-2012-0507 G”
To the best of my knowledge this was not detected by quite a number of CIS scans.
I would appreciate any comments on this matter, whatever persuasion they may be.
Thanks in advance.

Was it active in memory?
