Kaspersky said this isn't infected while 13 other AVs do

ok, you can ask him and let us know.
But i know that it is true.

 

If the .jar file came from the Java cache folder, it may be an old exploit that has been made ineffective with the latest Java patches. Better safe than sorry when it comes to malware, though.
SourMilk out

 

The file was in the path C:\Users\(My name)\AppData\Local\Temp\Low\

Does that help?

 

i have ask’d 2 from the kl team but non of them has answered me!!! maybe because there is no generic detection

anyway see this

i think this is what kl call it a generic detection

its not by signature!! ، its by behavior by the proactive defence

 

Proactive defense detections are behavior based - only detects behavior of the file while its running, not static detection (by just scanning).

Heuristic detections start with Heur, eg...
Heur.Trojan.Generic
Heur.Backdoor.Generic
Heur.Invader
Heur.AntiA
Heur.Downloader
Heur.KillFiles
Heur.StartPage
Heur.Worm.Generic
Heur.Virus.Generic
Heur.Infector
Heur.Script... (currently undergoing testing and tweaking)

Generic detections end in ".gen"
