I suggest you run the online scans that I have listed on my simple website to find out more.
JS = JavaScript
Agent = the name of the malware
CKL = the version of the malware
Trj = Trojan
Keep in mind that different vendors have different names for malware.
e.g. What avast is calling A, Kaspersky can call it B and Norton can call it C
You can use VGrep to find out who is calling it what.
