The choice is up to you:
1. See if spybot (www.safer-networking.org/index.php?page=download) or adaware (www.lavasoft.com) or pestpatrol (www.pestpatrol.com/pestinfo/s/sidefind.asp) are able to remove it (and presumably loads of other unwanted stuff). The first two tools are free; pestpatrol is shareware but claims to remove it.
2. Do it yourself with the instructions you find at http://www.google.com/search?q=sidefind+remove But this will leave the other stuff installed.
every time I turn My computer on and my main page comes up the sidefind on the left side of computer keeps coming up. How do I turn it off?
