This crap change you start website for rspark.com

try hitmanpro or malwarebytes for remove these.

It does not work. It deceives users about declared functionality.

Doesnt work, high jacks your search engine

This plugin adds some software that make https://search.rspark.com/?twd the default browser :@
Nothing change at "default browser" tab, so it's some type of malware. I solicite Firefox to try it and delete from the list of availables plugins.

doesn't work

Only adds an icon that doesn't do anything. All this addon can do is change your "New Tab" options.

Don't even think about installing this add on without knowing that it puts search.rspark.com on all new tabs. NOT COOL! I couldn't care less if the rest of the add-on works.

The author says to email for instructions on how to remove search.rspark.com. No, that's not good enough. It cost me more than 2 hours to figure out what caused this intrusive change to my new tab.
