The web protection of NIS 2010 is effective but like any other protection tools, it is not perfect. During the review, I visited a malicious site and performed unsafe downloads. NIS 2010’s Safe Web protection also missed protecting against an unsafe download. An example of the missed protection is when I tried to download a known malware; NIS 2010 not only allowed the download of the unsafe file but also rated the domain as a safe site:
When I enabled the SmartScreen Filter in IE to visit the same URL, IE’s SmartScreen Filter is fast to protect the computer against an unsafe download:
When Norton found an unsafe download or website, the Download Insight and Norton Safe Web would display a visible warning:
To test the real-time protection against malware, I transferred 260 positive malware to the computer. Norton has blocked and quarantined 192 malware but allowed 68 to be stored in the computer. That’s only 75% of protection by its real-time protection engine. To test the on-demand scan engine by Norton, I allow it to scan the 68 malware samples that the real-time protection engine has failed to block: Norton’s on-demand scanner has deleted 58 out of 68 malware and only leaves the system unprotected against 10 malware samples. Overall, Norton’s malware detection and prevention can offer up to 96% protection.
