problem with explorer.exe

Hello-

New user to this forum. My issue is that when I boot my laptop a windows box always pops up. I need to close it before getting to my default desktop. In the task Mgr I noticed that explorer.exe is running and upon looking in to the process I noticed that it refers to explorer.exe-0212ibia-pf. What is this prefatch ? Why is it happening and how can I stop it ? I did see posts related to this topic in the past but nothing exactly matching - my apologigies if I missed something. Any insight will be greatly appreciated.

Hello Anne :)

Are you using xp or vista?

Could you tell use exactly what the windows box says that pops up.

Are all your anti virus/malware scans coming up okay and you have all the latest updates?

Anything else out of the ordinary you have noticed?
