Norton does not deal with certain adware software that can hijack your browser and show unwanted adds, AdwCleaner can and does this very successfully, so I have always used and recommended this. On one machine with the exact same Norton security (same code number etc.,) it has no problem with AdwCleaner, but on another it keeps deleting it, until I have no choice but to switch Norton off, to allow Adw Cleaner to download and install, to get rid of an annoying piece of adware that Norton is incapable of dealing with!
Why?
