SearchRelevancy is a browser hijacker. It will redirect any searches you make through a major search engine, and put them through its own favorite search engines instead. Two of these engines are WebSearch and RedZip.
SearchRelevancy attaches itself to Microsoft Internet Explorer as a browser helper object, or BHO. This is a sure way for it to sneak past most firewalls, which will simply count it as a part of the browser.
If you would like to gain your freedom of choice back and be able to use the search engines you want to use, delete SearchRelevancy from your system by deleting the files and directories listed below. You can also use a free ZookaWare PC Cleaner scan to see if you have other unwanted files on your laptop or PC.
