Scour virus is a browser hijacker that changes your default search provider and redirects your search results to scour.com. It can be added as a toolbar to any of Internet browsers: Mozilla Firefox, Google Chrome, Internet Explorer or Opera. The search engine is supposed to deliver the most relevant results as efficiently as possible but the truth is that these results are blended with paid advertisements which makes it difficult to distinguish between them.
Scour virus might be installed intentionally via company’s official website but the most common way of getting this annoying toolbar is after downloading other software. Scour redirect comes bundled with it. It is a legal way of distributing adware and a computer user can blame no one else but herself. Usually when installing such software, additional applications are marked to be installed by default. If one chooses an automatic installation and does not take off a checkbox, she ends up with irritating changes to her browser.
It is particularly difficult to remove Scour virus because it does not have a usual uninstall guide. Most likely you will not locate it in your Control Panel Add and Remove Programs list or among browser extensions. Uninstalling and reinstalling an affected browser might not help as well. Most of anti-malware and anti-virus programs do not detect or even if they identify the file, its removal needs some manual changes to be made. Fortunately there are automatic tools available to remove Scour virus. If you choose to uninstall the toolbar manually, do not forget to scan your computer with several tools afterwards to ensure that no other infections are left.
