HSRemove will scan your system and remove the Home Search Hijacker parasite. Symptoms of being infected, usually include your home page rest to something like res://...dll, popup ads, and linked ad words in web pages.

If the program finds and successfully removes the parasite, it will reset your home page to the authors site and ask for a donation - you don't however have to make one - it's up to you.  You can reset your home page in the normal manner after that.
