Hello, I also deleted a jarfile C:\user\.jnana\jnana.tsa with viruses. Now a box keeps coming up telling me that the jarfile is missing. What the heck is this file anyway. Is it of any importance. I uninstalled and re-installed the Java File????

There's an entry in the Registry that is trying to start this file (which is the actual malware). Use a proper anti-malware program to remove the infection rather than just deleting the file.
