3048, 3 Errors keep occuring

I’ve been getting these errors intermittently 20 minutes after the computer starts and have no idea why I am all of a sudden
I use Windows XP and have the latest NIS.
I did a full scan, nothing. I done the NPS and it found nothing. I did the uninstall and reinstaller and it happened a few days after. I have also done the uninstaller and it still happens.

I really have no clue why it happens. It is quite scary starting the computer and not knowing if it will pop up.

It has suddly started happening again today after nearly 2 weeks. Any idea why this keeps on happening? I did everything it mentioned in the help as mentioned on the first post.
