Pros / Both Bitdefender Internet Security 2018 and Total Security 2018 dominated detection and performance tests at independent software testing labs and in our own in-house evaluations.
Cons / Internet Security doesn’t include online backup, but it is available with the higher priced Total Security software.
Verdict / Bitdefender is the best internet security suite we reviewed. It protects against known and unknown malware without causing too much lag on your computer as it runs.
Bitdefender Internet Security 2018 and the fuller-featured Total Security 2018 both earned high marks from third-party testing labs and performed better than other programs in our own detection and performance tests. Both excel at detecting and removing internet threats and they use few computer resources to do so. They both also comes with extra protection features, including parental controls and a personal firewall. For these reasons, Bitdefender Internet Security is our top pick for the best internet security software. Additionally, the higher priced Bitdefender Total Security 2018 is our top pick for premium internet security, as it includes more tools and safeguards (such as online backup storage and Android cell phone protection) than Bitdefender’s basic internet security program.
When we review antivirus and security software, we use test results from independent laboratories, such as AV-Test and AV-Comparatives in conjunction with our own in-house testing.
Bitdefender’s Internet Security and Total Security programs include the same antivirus protection included with Bitdefender Antivirus 2018. The software consistently blocked malware in independent tests, including new malware – often called zero-day viruses – that most antivirus software hasn’t encountered before. And it performed equally well in our own testing.
It automatically blocks and quarantines any malicious file until it can be labeled as an absolute threat, at which point the software completely removes it from your computer. If the file turns out to be benign, you can ask Bitdefender to release it so you can use it.
For the most part, Bitdefender doesn’t create too much lag on Windows computers – there was barely enough for us to notice as we browsed the web, opened programs and sent email. However, it wasn’t pronounced when we played games or watched videos online. We compared our results to third-party laboratory findings, and they had similar experiences with Bitdefender.
Scanning & Detection
Bitdefender includes more features than most computer protection programs. In addition to protecting against malware and phishing attacks, it alerts you to threats on social media and scans removable media to block malware entering through USB devices. It also has a gamer mode, sometimes called a silent mode, that postpones full scans and pop-up notifications so they don’t bother you when you watch videos or play online games.
Bitdefender’s cloud antispam feature registers spam attacks and sends the information to its defense cloud so it can quickly prevent other users from falling prey to the same attack. It also cuts back on legitimate-looking phishing schemes, and you won’t receive floods of unwanted emails.
Bitdefender Internet Security doesn’t back up your computer information online. However, you can create a bootable rescue CD that lets you manually boot and rescue your computer after a virus attack. Still, there is no guarantee all your files will restore as they were prior to the attack. If you upgrade to Bitdefender Total Security, you can back up 2GB of data online, which is enough to save close to 300,000 average-size files.
Internet Security doesn’t protect mobile devices, but again, an upgrade to Bitdefender Total Security 2018 gets you this feature, which provides same level of virus protection as the desktop version.
Privacy & Protection
Bitdefender’s firewall works in conjunction with Microsoft Windows security features to create a double layer of protection against malware threats. It also keeps hackers who want to steal your identity from swiping personal information.
The software’s parental controls help you keep your children safe online by blocking content you don’t want them to see. You can also control when they can surf the web and monitor their behavior online, including their Facebook activity.
Bitdefender has 24/7 live chat and telephone support. You can also email support representatives, and the company’s website has a knowledgebase where you can find answers to simple and common questions.
Bitdefender Internet Security and Bitdefender Total Security are the best internet security suites. Bitdefender’s programs earned perfect scores from third-party laboratories and our own reviewers for protection, and they earned above-average marks for performance. In addition, they include antispam features to reduce email spam attacks and parental controls to help you keep your kids safe online. Though Bitdefender Internet Security doesn’t have online backup services or mobile protection, both these features are included with Bitdefender Total Security for a higher cost.
