RUNDLL error message "jyku.fjo" on computer start up

Win XP.   Error message on start up...
RUNDLL
error loading jyku.fjo
The specified module could not be found.

Every time I start the PC this message is in middle of screen.

I have Webroot Spysweeper and McAfee Internet security for several years and not had a problem with them.
I think the problem started after my IE 8 crashed while on Google, and I think the webpage I was trying to get on had started to load Java, but the PC then froze.
Screen dump attached.
Thanks

•The deletion of jyku.fjo will fail if your Windows uses the NT File System (NTFS) and you have no write rights for the file. Request your system administrator to grant you write rights for the file.

Deleting Locked Files
You can delete locked files with the RemoveOnReboot utility. You can install the RemoveOnReboot utility from here.

After you delete a locked file, you need to delete all the references to the file in Windows registry.

To delete a locked file:

1.Right-click on the file and select Send To -> Remove on Next Reboot on the menu.
2.Restart your computer.
The file will be deleted on restart.

Note: In the case of complex viruses that can replicate themselves, malware files can reappear in the same locations even after you have deleted those files and restarted your computer. Exterminate It! can effectively eradicate such viruses from your computer.

1.On the Windows Start menu, click Run.
2.In the Open box, type regedit and click OK. The Registry Editor window opens.
3.On the Edit menu, select Find.
4.In the Find dialog box, type FILENAME. The name of the first found registry value referencing jyku.fjo is highlighted in the right pane of the Registry Editor window.
5.Right-click the registry value name and select Delete on the menu.
6.Click Yes in the Confirm Value Delete dialog box.
7.To delete all other references to jyku.fjo, repeat steps 4-6.
IMPORTANT: Malware files can masquerade as legitimate files by using the same file names. To avoid deleting a harmless file, ensure that the Value column for the registry value displays exactly one of the paths listed in Location of jyku.fjo and Associated Malware.

I hope this works for you! :D
