Bitdefender is our top pick as the best antivirus program in 2023. It provides watertight protection across all of your devices because of its wide range of features. The latest packages include a variety of useful tools, such as an advanced web filter and password manager that helps secure your data. Bitdefender's family-friendly security package provides extra protection for up 10 tablets or computers as well as a generous three-month money-back guarantee.

Webroot is a fantastic alternative to the major names in the industry, offering rapid and accurate protection against malware with minimal impact on your system resources. Its lightweight engine is capable of scanning within just 20 seconds, and its clever 'firewall' monitoring and effective real-time anti-phishing and identity theft protection all impress in our tests. The big independent labs don't rate the basic antivirus software however, the upgradeable versions include Internet Security Plus with its more comprehensive features and an excellent family suite that includes additional online privacy tools.
