What kind of application is Smilebox Tab?
After testing the Smilebox Tab browser extension, we found the purpose of this app is to hijack a web browser. It promotes smilebox.co (a fake search engine) by changing the settings of a web browser. It is common for browser hijackers to be promoted and distributed using shady methods. We discovered Smilebox Tab while inspecting deceptive pages.
Smilebox Tab browser hijacker overview
Smilebox Tab hijacks a web browser by making smilebox.co the default search engine, homepage, and new tab page. It forces users to browse the Internet using a fake search engine. Smilebox.co redirects users to search.yahoo.com - it shows results generated by Yahoo, a legitimate search engine.
Fake search engines should not be trusted. They can redirect users to untrustworthy pages, include links to dubious pages in their results, and show results generated by shady search engines. Most browser hijackers do not allow users to undo their changes while they are added to browsers.
It is required to remove browser hijackers before the affected settings can be reverted to their previous state (before the default search engine and other settings can be set to the desired ones).
