Crawler

Posted: February 23, 2010

Crawler is a Internet Explorer toolbar which provides a pop-up blocker, additional search functions, links and other useful features. However, it may also maliciously redirect web searches to rogue websites and change the Internet Explorer default error page. Crawler must be manually installed. It runs every time the user launches Internet Explorer. To remove Crawler use a proven anti-spyware program to make sure it has been terminated.
