Question about your domain

I just got an error [in spanish] on my machine which I cntrl+alt+delete->End Task'ed after getting a rough translation (my Spanish is kinda rusty). Here it is (the translation):

"The analasis of something isn't finalized... there are errors present in the archives... perhaps causing the computer to act in an erratic or unpredictable manner, and block?. Realize a rapid analasis completed slowly with WinFixer 2005.
Discard WinFixer 2005 for detecting and repair errors in the registy now? (recommended)"

Please explain?
