Hello,

I must note that I do not know of this "trojan" (if it is one).

Make sure your antivirus program is up-to-date.

Let me suggest you flush the Java cache. First close all browsers.

go into the Control Panel (using Classic View) and double-click the Java Icon. (looks like a coffee cup) javaicon.gif

  • On the General tab, under Temporary Internet Files, click the Settings button.
  • Next, click on the Delete Files button
  • There are two options in the window to clear the cache - Leave BOTH Checked
    Applications and Applets
    Trace and Log Files

  • Click OK on Delete Temporary Files Window
    Note: This deletes ALL the Downloaded Applications and Applets from the CACHE.
  • Click OK to leave the Temporary Files Window

Let me also suggest you insure you have the latest version of Java runtime.

To test your Java Run-time, you may go to this page http://www.java.com/en/download/help/testvm.xml

When it has the latest version, you should see Java Version: Java 6 Update 20 from Sun Microsystems Inc.

Also, I suggest you do an online scan at Kaspersky, to get another "check".

Note Kaspersky does not do any removal. It is a scan and report only.

First, Download TFC by OldTimer to your desktop

  • Please double-click TFC.exe to run it. (Note: If you are running on Vista or Windows 7, right-click on the file and choose Run As Administrator).
  • It will close all programs when run, so make sure you have saved all your work before you begin.
  • Click the Start button to begin the process. Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two. Let it run uninterrupted to completion.
  • IF prompted to Reboot, reply "Yes".

Next: Do an online scan at Kaspersky

Kaspersky Webscan Online Virus Scanner

Do not post any logs here. Let me know in case Kaspersky finds something (other than cookies).

i have done a scan with kaspersky and it found nothing,then did scan with norton also nothing found,then with malwarebytes and found nothing.I guess that removing all the java cache and reinstalling the program has got rid of it.Should i turn off system restore and then turn it back on to get rid of the old restore points?

Thanks

Good results. You may if you are inclined do a cleanup. Run Disk Cleanup with the System Restore Cleanup as outlined here by Bert Kinney, MS MVP

This is for XP systems:

This is for Vista systems:
