I am using OS X 10.9.5
When every I click in any browser, it creates a new tab with some site like "www.detoxmymac.com".
It seems that the computer is full of processes running while I run any browser. Consumes huge power. How can I stop it.

Have you seen Vimium for Chrome?
I'm not sure if there is a way to hide the toolbar in Chrome, but the vim extension for Safari might be the last step you need for navigating using only the keyboard.

In addition to running anti-virus software, as mentioned by Steve, above, you should check and clean out your browser's cache and extensions.
(1) Safari
Here, plug-ins called "Quicktime" and "Flash" are OK, and are not likely culprits.
Here, think long and hard about whether you actually need the services offered by any extension here. If you do, check you've got the latest and disable or delete the rest.
Here, check to see if there are any proxies, which are instructions to visit some other site before going to the site you wish to visit. Sometimes proxies are needed to get past restrictions put on you by your ISP, like the hotel you're staying at, but they're uniquely positioned to redirect you anywhere, and to pop open new web pages.
(2) Chrome
Check here for any extension you don't recognize. Disable or delete anything you don't need.
Set your search engine to something you recognize and trust. If you're in doubt, use "Google" or "DuckDuckGo" or even "Yahoo!" and delete the rest.
Click here to look at your proxy settings. Unless you need a proxy because you travel a lot, or you live in a repressive country, or your computer is part of an enterprise network, you probably don't need a proxy.
