Summary: Norton is one of the best out there. It does not suck up system resources like other virus and spyware programs. Have been using this product for 4 years and have not had any issues at all. It does an excellent job.
Summary: I had let my previous copy of Norton 360 expire. My computer had already picked up a worm in the interim that was slowing it down. The new edition of Norton 360 caught it and cleaned things up right away. Good product. Been using Norton for a dozen years.
Summary: I have been using Norton (Symantec) Antivirus for years and have never had an issue with them or has their AV missed an attacker. I like 360 because if the Identity safe (maintains my passwords and speeds up logging in), PC tune up tools, keeps my PC's running, performing at their best.
