Over 300,000 new types of ransomware and other potentially malicious software are discovered daily, according to the IT security research institute AV-TEST. Computer viruses can slow down your devices, create a sea of pop-up ads and even erase or steal personal information.
Antivirus software can defend your devices from threats and protect your data. CNBC Select reviewed dozens of antivirus software and narrowed our top picks based on nine categories. The ones we selected continuously scan for threats, have strong third-party testing scores, do not substantially impact overall device performance and are compatible with PCs, Macs or both. (See our methodology for more information on how we chose the best antivirus software.)

Our methodology
To determine which antivirus software is best, CNBC Select analyzed and compared dozens of antivirus programs. e focused on antivirus providers geared toward individuals and small businesses, not strictly enterprise-level, and reviewed them on this set of criteria:
- Comprehensive protection: An antivirus software should prioritize the safety of the user and their information. The antivirus should be able to monitor, identify and eliminate various harmful types of malware. False positives should be kept to a minimum.
- Cost: Antiviruses are generally offered with monthly, yearly or multi-year subscriptions. We considered not only the cost but whether the service offers a free trial period, limited free version or money-back guarantee that allows you to test the product. The cost of the services mentioned are up-to-date at the time of publication. Some services may offer limited free trials depending on what platform you subscribe through, however, we only considered offers publicly available through a browser.
- Compatibility: Users should be able to run the antivirus software on PCs, Macs or both.
- Antivirus Lab Testing: Results from third-party, impartial antivirus testing labs will be taken into consideration.
- User experience: An antivirus software should be easy and streamlined for users to install and set up.
- Computer Performance: While antiviruses work on your computer in the background, its scans and actions shouldn’t demonstrably decrease the performance of your machine.
- Additional features: Some antivirus providers offer additional tools in the form of virtual private networks (VPNs), parental controls, identity protection and other helpful products.
We narrowed down our ranking by only considering antivirus software that both passively and actively scans for threats, receives strong third-party testing scores, does not substantially impact overall device performance, and is compatible with PC, Mac or both.
