Viruses and malware are the most frequent threats for computer users. They can steal sensitive information like passwords, slow your PC, and even stop it working. The most effective antivirus software will stop this from happening and will keep you safe online.

Antivirus programs guard against an array of security threats, including ransomware and spyware. They also shield you from rootkits, trojans such as worms and phishing, as well as adware. They can also stop incoming attacks by monitoring your network for suspicious activities. You should choose a software that offers 24/7 support and a thorough knowledge base or FAQ section, in case you need to ask questions. A money-back guarantee is an excellent option in the event that the software doesn’t function as you expected.

All of the best antivirus software programs we have listed provide top malware protection and a variety of other security measures. Some are available as premium versions with additional features, such as a VPN or password management system and encryption. It’s important to keep in mind that most of these applications require a subscription and only work with Windows devices.

If you are seeking a cost-effective alternative, Malwarebytes offers excellent malware detection rates as well as additional protection for your web with its no-cost “Antimalware Pro” product. It also comes with a basic service that doesn’t interfere with your other antivirus applications installed on your system and runs quite quietly in the background. This is the best choice if you want a quick scan or want reassurance that your system has been slowing down, although it does not include any other security features and may display annoying pop-ups trying to make you switch to paying for a premium version.
