Bitdefender Internet Security produced remarkably competitive results during Windows 7 testing in January and February of 2014 and then again in Windows 8 testing during March and April. The tests measured effectiveness at protection against malware, effect on host-machine performance, and usability in terms of how accurately the software diagnosed malicious and safe files.

In terms of performance, Bitdefender Internet Security running on Windows 7 detected all of the 17,794 malware samples, compared to a 97 percent industry average. In the Windows 8 tests, Bitdefender repeated its perfect score by detecting all 20,646 malware samples, compared to an industry average of 98 percent. A more difficult performance test exposed Bitdefender to brand-new malware, called zero-day malware because when it arrives, it has never been seen before, so there are no threat signatures to help with identification. Bitdefender correctly identified all of the 151 zero-day samples on Windows 7 and all 138 samples on Windows 8. The industry average on Windows 7 and 8 installations was 94 percent detection of zero-day malware.

Performance tests on Windows 7 and Windows 8 measured whether the internet security suites slowed computer speed while surfing the web, installing applications and copying files. Bitdefender slowed its host computers by an average of one second, compared to three seconds for the rest of the competitors.

There were also tests to measure usability in the sense of how well the products could tell the difference between safe and threatening files. Just as the boy who cried wolf, if your computer security software falsely alerts you too many times, you might ignore them. On Windows 7, Bitdefender made no false alerts, compared to an industry average of three. On Windows 8, Bitdefender had one false blockage, compared to an industry average of none. Nevertheless, it is an excellent usability score.

Bitdefender Internet Security 2015 adds features to your computer to improve its security. The software protects you from malware and phishing attacks and alerts you to possible harmful situations on your social media. It also has intuitive functions that detect what activities you are performing on your computer and throttles back communications in response. So if you're watching a video, it won't activate pop-up windows for minor security threats.

Bitdefender is a suite because it offers you a firewall, cloud anti-spam and parental controls. The proprietary firewall included in Bitdefender Internet Security 2015 is intended to replace the need to use the Windows firewall. Yet, the firewall doesn't score well on tests performed by Matocsec, a firewall software tester. However, you can use the Windows firewall in place of the Bitdefender version. The cloud anti-spam filter helps to limit the total amount of spam you receive by actively looking at spam emails sent to all Bitdefender users. The parental controls included in Bitdefender Internet Security 2015 help you to monitor and control where you children go online, including social sites like Facebook.

Bitdefender Internet Security 2015 continues to be the best internet security software on the market. It outperforms other internet security software in independent lab tests. The included firewall isn't as impressive as the rest of the internet suite, but the suite is among the top of internet security reviews. Bitdefender Internet Security 2015 is the best internet security software.
