It's a Java Virual Machine class which are mostly used to quietly extract user info. Might be part of Kazaa - is or was Kazaa ever run on this machine? Could be spyware other than kazaa but my quick search showed mostly Kazaa as the perp for this one.

Install/run Ad-Aware 6, build 181 + updates + set to deep-everything and se what it finds.

The "problem" is related to verifierbug.class superclass in Java, and of course it appears via JVM. Well, the problem is that this security flaw is well known to Microsoft, but they are not doing anything to fix it - go figure. This particular class (not designed as a trojan keylogger) is responsible for taking notes on your keystrokes and processing them. Verifierbug.class is not designed to be a virus, or a trojan. There may be some bugs in the code that cause the Norton to detect it, because it carries the same signature as some known viruses.

The problematic folder .jpi_cache downloads all necessary classes to run a certain Java Applet. So, even if you delete the folder and contain the so called infection, next time you visit a site that has applets, the folder will be recreated. Important thing to note is that some of the sites you have been visiting place the infected file in this folder (which I assume has to be in the jar folder). So, each time you go back you will pick it up again.

 

There is really no known way of protecting yourself against this problem. But I can give some good ideas how to protect yourself:

 

1. Download the latest cumulative patch for IE. This seemed to work for some people.

 

2. Try to figure out after which visited website the virus appears. Of course, let the tech support know about it, and stop visiting the site.

 

3. NOT particulary recommended step is to disable the Microsoft VM in the Internet Options of your browser, and see what happens.
