NIS bears so little resemblance to previous editions of the same application in a good way that it’s probably no exaggeration to say this is a whole new program from the ground up. After many complaints by reviewers and users alike about the program’s slow interface and large memory footprint (among other things), Symantec’s engineers went back to their labs and turned out a slim and trim, drastically revised piece of work that might change users’ minds about Symantec’s desktop products.
Installer and virus files to my target PC, IS intercepted and destroyed them each time no matter how I tried to enter them. Among the other new safety features in NIS is the Security NIS doesn’t use pregenerated whitelists or blacklists exclusively to handle applications automatically, it uses heuristics to interpret a program’s origins and behavior. For instance, if the user has downloaded, installed, and run a program from a safe Web site without incident, NIS will unblock the site in a way that reflects that.However, Symantec NIS does lack some things. For one, the antiphishing system seems a bit behind the curve; it’s only available as a plug-in for IE and pops up a warning balloon over the offending page instead of redirecting the user to something else entirely. NIS also doesn’t include spam blocking, which is sold as a separate product.
