Yes, you can. Norton is a trustworthy cybersecurity company that’s been in business since 1990. With a staff of nearly 3,000 employees, Norton’s malware databases are constantly updated, allowing it to maintain outstanding malware detection rates ( perfect in my tests ). In fact, Norton is so trustworthy that it even offers LifeLock protection to help protect your identity from cybercriminals looking to steal it.

Will Norton slow down my computer?

No, Norton won’t slow down your computer. During my tests, I found there was minimal impact on my system, even when running full system scans. What’s more, Norton comes with features to boost your computer’s performance. For example, the Norton 360 for Gamers package includes Norton GO, a tool that can optimize your computer’s RAM and CPU usage so that you can game without any slowdown — all while enjoying the protection that Norton provides.

Norton isn’t free — but for users on a budget, the Norton 360 Standard plan offers excellent antivirus protection for 1 device (3 devices if you’re in the US). Norton offers a pretty good first-year discount, and you can try all of its features risk-free with a 60-day money-back guarantee.

Can I disable Norton?

Yes, you can either temporarily disable Norton or uninstall it entirely. However, this could leave your system vulnerable to malware, web-based attacks, and more, so I don’t recommend doing so. If you’re an advanced user and trust a particular program that Norton is blocking, you can whitelist it so Norton doesn’t flag it.

Does Norton protect against ransomware?

Yes, Norton provides strong protection against ransomware . Its security software is designed to detect and block ransomware attacks before they can encrypt your files. Moreover, Norton’s automatic cloud backup feature acts as a safety net, offering a backup of your files in case they get encrypted by ransomware. With constant updates to its malware databases, Norton ensures it stays ahead in the ever-evolving landscape of malware, providing solid protection against ransomware and other threats.

What’s the best Norton package?

Norton 360 Deluxe is the best choice for most users. It provides a ton of useful features for up to 5 devices across Windows, Mac, Android, and iOS. But if you only need protection for up to 3 devices (or 1 device outside the US) and don’t require parental controls, Norton 360 Standard is a decent choice too. In certain countries, Norton also offers 3 packages with LifeLock ’s identity theft protections. Users looking for the very best protection from Norton should invest in Norton 360 with LifeLock Ultimate Plus . The package includes antivirus protection for an unlimited number of devices and comprehensive identity theft protection for 1 primary user — you can easily add additional family members for identity theft cover (but it is a bit pricey). However, most users will be perfectly happy relying on Norton 360 with LifeLock Select for a more basic but still adequate antivirus + identity theft protection package.

Does Norton work for iPhones, Androids, and Chromebooks?

Norton provides mobile apps that work for iOS devices and Androids, but Chromebooks aren’t officially supported. That said, several of Norton’s Android protections still work on Chromebook . This includes Norton’s app advisor, dark web monitor, and anti-phishing protection (if you install Norton’s browser extensions).
