Norman is an antivirus company that has one of the oldest history known in the industry but its influence is totally gone as it fell behind and got outdated ever since the early 2000s. I once use their v5.7 antivirus and it was a pathetic experience. Nevertheless, their latest version, Norman Security Suite v8 seems to have far more positive reviews than previous few versions i've known. You can read one of the reviews here.
Now you can try out this new antivirus free of charge, for 4 years straightout; no license keys needed: all you got to do is to download the DnBNOR Special Edition installer from here and install it! The DnBNOR Special Edition of Norman discarded certain features such as the Intrusion Guard, Privacy Tools and AntiSpam module from being free but users will still have the Antivirus and Antispyware protection feature, the all-new Norman Personal Firewall and Parental Control for 4 years worth. That is quite a sufficient protection level for most users out there.
I tested Norman Security Suite v8 DnBNOR Special Edition on my virtual machine and well, i think it is a pretty excellent suite although i did not test its effectiveness against malwares. It has a pretty solid look, is quite stable and much more responsive compared to previous version. One open of the task manager and i realized that Norman has also started separating its security processes into many clutters (similar with F-Secure and G DATA) so as to increase responsiveness and prevent crashes from bringing down the entire suite. Smart thinking, Norman!
Verdict: I would say it is a solid suite to keep and remember, it is also the first Norman product to officially support Windows 7!
So grab your chance while you can. After all, how many antivirus software vendors out there are as kind as to offer us 4 years' worth of free protection nowadays?
