What is Cactus-search.com

Cactus-search.com is a questionable browser extension that can take over web browsers without users’ consent. Due to this reason, it can be categorized as a browser hijacker. Browser hijacker usually spreads around via other freeware installations and changes browser configuration once it achieves the target browser. As a result, users are forced to use Cactus Search unless they get rid of the browser hijacker. Even though it looks like a legitimate search engine, you should not become deceived, as it is designed for only one aim – to generate advertising revenue from users’ clicks on links or redirects to third-party websites. The thing is commercial content is not controlled by the search engine creators so there is a huge possibility to get exposed to malicious content or even install malware on the system. You can remove Cactus-search.com in two different ways. If it is difficult for you to deal with the manual removal of OptimumSearch, you should definitely use the automatic method.
