Before you got hit by hxxp://www-search.info/?originaloriginalsrc="us, it doesn't appear as it own name. It shows up as hxxp://usa-aa.s3-website-us-east-1.amazonaws.com/?grp=9. That's to say you get hit by hxxp://usa-aa.s3-website-us-east-1.amazonaws.com/?grp=9 and the it redirects you to hxxp://www-search.info/?originaloriginalsrc="us. Once hxxp://www-search.info/?originaloriginalsrc="us gets on PC, it adds its add-ons or extension to the target browsers to modify browser default settings and makes it difficult to reverse it back to the originals. This happens in the background without your awareness. Some victims tried to clear the add-ons to eliminate the mentioned redirect. It seemed working at first. But after restarting the browser or rebooting the computer, they got redirected to hxxp://www-search.info/?originaloriginalsrc="us again.
