The most reliable online antivirus safeguards your computer or laptop (and often other devices like routers and IoT home appliances) from malware, ransomware, cryptojackers and phishing attacks, data breaches, and more. A lot of antivirus programs offer extra cyber security tools like dark web monitoring, device optimization, and identity theft protections that are included in paid plans.
The most important aspect is a reliable antivirus engine. It’s crucial that any antivirus program detect threats with a high degree of accuracy. Other factors can also help with this, including a strong detection engine for heuristics as well as behavior-based security. You’ll also want to make sure that the antivirus program has a large number of anti-malware signatures in its database, as well as a deep and robust set of scanning techniques.
Windows PCs and Macs have built-in anti-virus programs, but they are not the same as third-party applications. It’s not always equipped with an up-to-date malware database, which leads to missed threats. It’s also not equipped with some of the internet security features which make third-party antivirus such a useful tool. These include parental controls and advanced phishing security and web-based security features.
Avast, Norton, and Kaspersky are the three top antivirus programs available. Avast’s program is simple to use and boasts high malware detection rates, according the independent lab AV Comparatives. The parent company was snared in the year 2019 for selling encrypted data to third parties via its Jumpshot service. Since the time it hasn’t taken steps to clean up its actions. Kaspersky is a similarly reliable option that has a decent detection rate and a vast range of internet security options such as a memory firewall, banking tools and VPNs.
