I accidentally installed a bunch of adware and browser hijacker after installing a piece of new software from insecure website. As I dealt with some threats before so I was able to remove almost everything permanently except for the Coolsearch.Info browser hijacker. It has changed the default settings of Chrome and Firefox. My removal tool could not detect this malware on system because it said this threat was removed successfully at the first time, but it usually came back. Does anyone know how to fully delete it and avoid it coming back? All help will be greatly appreciated.
