Расширение устанавливается само. Удалял три раза. Удалите его вообще отсюда. Что это за вирус?

This is very strange and suspicious behavior from Maxthon...

This search tool appears to be unremovable and makes even simple browsing a pain. Ever since it installed, it keeps bringing me to custom search (so I had to create another search engine). Please make it possible to remove this. If I didn't like Maxthon so much, I would have instantly switched to another browser.

Go to Settings-> Search engine Now from the 'Search Engine Management' section select "Google" and then remove it by clicking 'Delete'. Once deleted, click on 'Add from recommended search engine' and then select Google. At last make sure Google is selected as the default search engine from the 'Default search engine' section on the top. Now you can close out from the settings tab at start googling ! Hopefully this will solve the problem. Have a nice day ! :)

The original Maxthon has neither virus nor adware, even malware in general. Users sometimes got their PC infected by installing programs along with adware. They will infected to all known browsers, all program's shortcuts which you click everyday! To save your time, make sure you know what you're doing (install only the specific program, etc) and don't forget to read more. There's a world where no antivirus in your PC, full control, joy of speed. "One Piece" is real.
