Internet keeps popping up in right lower corner, running multiple searches. Also everyone states 'you are using an unsupported command line flag, no sandbox. Stability and security will suffer. Ran complete Norton scan, did not find anything. Also states 'google chrome isn't your default browser. Occasionally small window pops up, stating 'not sandboxed'. Examples of search, 'scooterbros.com/game', sonicraid.com/game, oddretro.com, saymommy.com/c/video and many more. Cannot seem to stop them from popping up. Any help would be appreciated.
