Antivirus Software Reviews

Computers have transformed nearly every aspect of our lives including helping students learn, monitoring patients in hospitals and controlling critical manufacturing processes. This increased dependence on computer devices has also led to an increase in cyber-attacks, including malware, viruses and ransomware. Antivirus software is designed to recognize these threats and prevent them from causing harm to your PC or stealing personal information.

When selecting an antivirus program it is important to look at the ability to scan for viruses and whether it comes with a firewall and how well it does in independent lab tests. You might also want to take a look at the customer support, how often it updates itself and the number of devices it is able to protect. Certain programs, like Norton have additional features that help you avoid identity theft and protect your privacy online.

Top programs provide multiple security options. These include heuristic detection which identifies behaviors that are typical of malware or viruses and signature matching that compares files to a list of known malicious codes. Some programs use sandboxing to isolate suspicious files in an environment that is sealed and safe from any harm.

A few of the top antivirus software is free. However, they might not provide as many features as paid alternatives. For instance, Bitdefender’s complimentary version scored very well in our tests and has a firewall, while its premium version comes with parental controls along with a file shredder as well as a password manager. Similar to that, Malwarebytes’ free version earned top marks in AV-Test for 2023 but failed in our test of usability. Intego Mac Security X9 comes with an impressive set of tools which include VirusBarrier and NetBarrier that removed and identified the most malware threats during our test.
