Norton Antivirus Free Download: How it Works and Benefits
You are interested in using Norton Antivirus to protect your computer but aren't exactly ready to buy yet. Viruses, spyware and hackers don't wait however, so you need protection now. What to do? Try it for free!
With our Norton Antivirus free download, you can be protected against most online threats within minutes. Just click the download button above and follow the directions. Installation is extremely fast and takes less than one minute. Once running, Norton Antivirus will work discreetly in the background so as not to impact your system's performance.
You will be downloading the full version of the product, there are absolutely no feature restrictions with the trial. Some benefits of getting protection via our Norton Antivirus free download are as follows:
First, this latest release of Norton Antivirus is extremely light on system resources. So light, in fact, that the Gaming Edition offered last year was discontinued by Symantec. This Gaming Edition was optimized so as not to hamper the performance of PCs used to play games; with Norton Antivirus' latest release, computer performance is never an issue. Not to mention installation usually takes under a minute - make sure you completely remove all previous antivirus software installations, however. Start with a clean state, in other words!
Second, Norton Antivirus now employs two powerful methods to block and eradicate viruses:
- Signatures, which are software patterns of known threats stored in databases; these patterns are compared to application code found on your computer to see if there's a match, in which case the application is tagged as a threat and removed.
- The SONAR 3 technology is able to 'observe' the behavior or applications and by using online intelligence it can actually tell if an application is doing something bad, even if there's not signature for it. This means you are protected against threats that have not been officially identified yet!
You can enjoy our Norton Antivirus free download for 30 days. A credit card number is required to secure your download, however it won't get charged until the trial period is over. If you don't like Norton Antivirus, simply cancel your trial within the 30 days at no cost to you. If you do think Norton Antivirus is the security product you need, don't do anything and you will get billed automatically for 12 months of protection (a full yearly subscription).
