I have not seen any error reports for a long time now (touch wood), but that looks a bit strange. Were are the buttons to send or do not send?
Have you tried Ad-Aware
http://www.lavasoft.de/ ? It would surely find any spyware and clean your drive.
But sometimes the only thing to do is to reformat the drive (or use recovery CD).
...have to go, my family is already standing in the door, rle calling.
