.jar file circulating on facebook like a virus, any insight appreciated
Hi, I'm really not sure if this is the right sub-forum, but here goes.
I got a message on facebook from a friend, saying someone else had set up a profile with my name and pictures etc. There was a link attached to a file named IMG_060774.zip. I looked in the .zip, and found IMG_060774.jar. I contacted my friend and told her not to open the file, but she already had. She'd got the same message as me, only with her own name on it. When she opened it, it started sending the same message with the same attachment to everyone on her friends list.
She logged out of facebook when this started happening, but it started sending the messages again when she logged back in. All could think of was to advise her to restart her pc to kill the running process.
So, what I'm here to ask is, could executing this jar file actually install bad stuff that will remain on a pc, or is it just some benign process that would have died with a restart.

Java, just like any other "real" language, can do pretty much anything on a computer. This isn't inherently a bad thing, but it can be used to do bad things (just like a hammer can be used to break glass instead of hammer in nails). Running a jar is no different from running a .exe or other arbitrary programs. So, the gist is this: yes, a jar could install bad stuff. I highly suggest you run an antivirus program.
