Combofix still doesn't work on this computer, I'm afraid. It runs until it says "Completed Stage_50" and then it stops with the same error message as described earlier. No Combofix log anyware.

I ran Kaspersky. The log is included in this post.

I have now removed Java update 3 and 5.

The system is much better! I haven't seen any problems since I ran Malwarebytes' Anti-Malware after your first reply.

Best Regards,
