I searched the Internet for any information concerning this file, an executable .jar file. According to Sophos (http://www.sophos.com/virusinfo/analyses/trojmultidrdw.html) this is dropped by a trojan along with another file, CSrss.vbs.zip.

I ran ClamWinAV on the file and it did not find anything.

Is this something about which I should be worried?

A search on Google, Ask.com, Dogpile & Surfwax turned up only a few hits, and most of them were about HijackThis output.

Thank you!

I think I found out some information concerning this file:

http://www.ej-technologies.com/products/exe4j/overview.html

exe4j is an EXE creator for Java; it seems as if any program, legitimate or not, can use the library file, exe4jlib.

I've looked at some of the code for this, but I don't know enough about Java to see if it's benign or not.

Thanks, I ran the file through their site & none of the anti-virus programs had a problem with this file; however, I did not think they would. It seems as if it can be part of a trojan drop which is used to run the actual virus program. The .jar file is only the actuator rather than the virus. It can also, I believe, be used to install legitimate programs.
