Mycoolsearch.com

Mycoolsearch.com is a basic search engine that will redirect all search queries to the Yahoo Search, so it is safe to assume that it will deliver reliable search results for now. However, it is likely that the administrators of Mycoolsearch.com are receiving an affiliate fee from the Yahoo Search whenever they refer a search query to them – this is probably the reason why Mycoolsearch.com is being promoted with the use of browser hijackers and Potentially Unwanted Programs (PUPs) that are designed to manipulate your browser's configuration aggressively.

If you see Mycoolsearch.com whenever you initialize an online search or try to open a new tab regularly, then this behavior is likely to be caused by a browser hijacker or PUP that has latched itself to your Web browser. This is not a major security concern, and it is not something that you should worry about too much. However, if you are dissatisfied with the changes, you should remove Mycoolsearch.com from your browser's configuration by using a suitable PC security scanner.
