Quick Research: I did a Google search on "SurfBuddy remove" and located the following related message
from http://www.surfapps.com/sbuddydll.html:
"sbuddy.dll" is a spyware package currently circulating the internet.
It was not developed and is not included with any surfapps.com
software, and it is not part of surfapps.com's SurfBuddy Surf
Companion software. Please view our Privacy Policy for more
information about Surfapps.com's policies on spyware.
What I Did:
1. Looked at c:\program files\SurfBuddy, found the file, and failed to delete it directly:
>dir c:\program files\SurfBuddy
sbuddy.dll
...
>rmdir c:\program files\SurfBuddy
sbuddy.dll in use
2. Run HijackThis > "Open the Misc Tools section" > "Delete a file on reboot",
select c:\program files\SurfBuddy\sbuddy.dll, and reboot the system.
