windows defender won't have any clash with AV i suppose. However having two AV's in one PC might clash
Norton is not bloat.NONE of the bloat (consuming CPU, RAM, and disk resources) that is associated with Symantec and McAfee.
Norton is better than was in past years, but it still takes up a lot of disk space and a large chunk of RAM, and for many, it noticeably degrades overall system performance.
