Norton Security (For 5 Devices) [Download] (Old Version)I have been using Norton security software for over 10 years and it has never failed to ensure that my system is both protected as well as operating at peak efficiency. This is important for me as I have used my system for tasks ranging from alpha/beta testing of online games, AutoCAD development, programming in multiple computer languages, graphic design and remote computer support/repair.I originally started out with Norton Internet Security and later transitioned to Norton 360 and with the streamlining of the product selection by Symantec (parent company), I am now using Norton Security. I have been both an end user as well as a marketer of this software while working in the retail environment for 10 years. Whenever I had a customer come in requesting assistance with removal of "malware" or "viruses/trojan/etc" on their computer, young or old, novice or expert, I always recommended this product first.Hands down this is the most reliable and most effective computing software package to not only prevent malware from both being downloaded as well as to prevent install into any of your applications, but it also has built in tools in the primary user interface to automate the optimization of your computer's system performance. Add to this the option for online data backup to store your precious family photos, confidential financial and legal documents, home movies and much much more, and what you end up with is a total protection package.The most common complaint I have always received when recommending this product whether it be the Norton 360 version or the current Norton Security Deluxe is that "It is too expensive" or "I heard that it will slow down my computer too much" or even "I saw in Consumer Reports that X branded free software is the highest rated". Well, here's the actual facts to each of these retorts:1. Norton 360/Norton Security Deluxe sells for $20 every single Black Friday, making it cheaper than 95% of all comparable security software on the market.2. What will slow your computer more? Having the security software keeping your computer clean and optimized, or getting infected/bogged down by unneccessary temporary files (internet temp files, windows user and system error logs, old install packages, old update files)?3. Consumer Reports and by the same token, almost every review agency online and in print almost always makes a comparison without taking into consideration total value, meaning the free software always wins the competition. Is the free software effective? Maybe. Maybe not. Is it on the same level of capability as the subscription-based security/system optimization software? Absolutely not by an astronomical margin! Comparing free security/system optimization software to the subscription-based software is like comparing a bi-plane with a prop to a 747 jumbo jet. Sure, both can technically get you to where you're going, but the reliability and efficiency between the two is so radically different as to make the comparison invalid.In the end, you only need to make one decision to determine if this software is for you. Do you plan on keeping your computer for more than 3 months? If your answer is yes, get this software. If not, go ahead and use the free software provided by your Internet Service Provider (ISP) with the cautionary warning not to keep anything on the computer you would be upset to lose.For reference purposes, I have inserted the product link for the version of Norton software that this product replaces/upgrades as of Symantec streamlining their product offerings.
