Do I need to keep this file on my computer for it to run properly? ~ arr3.jar-1bde...

This is most of the name of the file ~
arr3.jar-1bde2f45

Is this something I need to have on my computer in order for it to run properly???

Nortons said it was infected, so I've got it in the trash, but before I chuck it out, I want to make sure it's not a system type file.

It was in doc and settings folder deeper down in a folder called Sun, .... and on and on ~

Any insight on this would be greatly appreciated..

thank you

You are safe to delete it as it is most likely infected. There are many trojans infecting by means of java so clearing the java cache is a good idea as well.

Clearing the Java Cache

• Click Start | Settings | Control Panel
• Click the Java Plugin Icon
• Click the Cache tab or sometimes depending on the java version it may be called temporary files
• Click the Clear button and click OK to confirm
• Note: Please repeat this procedure for each "Java Plugin" button in your Control Panel
