As a start, run Spybot and Adaware (use Google to locate
them). If that does not help, do a Search within your OS
for that file and delete the files that you find but don't
empty the Recycle bin (just in case you need to reinstall
the files). Reboot and see if your computer is running
normally. If it appears to be running normally, then
download Regseeker from
http://www.onlythebestfreeware.com/program.asp?
program_id=30 and use it to search for "almighty search".
Before delete the files that it finds, make sure that you
have the Backup box ticked (again just incase you have to
return the files to the registry). Good luck.
