The most reliable antivirus software provides solid protection against malware and several cybersecurity defenses and superior performance across all operating systems. It should be lightweight on your system so that it doesn’t slow it down or even crash.

Traditional antivirus programs looked for viruses by examining files when they were written to disk on a device or downloaded from the internet. If a file was suspicious, the program would remove or quarantine it, thus preventing the spread of malware. This software was great at fighting viruses that were common but as the number of new malware threats increased quickly over the past decade, older antivirus tools struggled to detect new attacks and stop them from causing damage.

Antivirus replacements that are sometimes referred to as EDR (Enterprise Endpoint Detection and Response) solutions, utilize a full set of security technologies to detect and block everything from common malware to new attacks that have never been seen before. This approach has proven to be more effective than traditional antivirus tools that rely on signature-based detection.

If you require an antivirus program is contingent on your level of common sense and how much you use your computer. A reliable antivirus program is vital if you use sites that are not safe, download pirated programs, or do not have any other form of cybersecurity protection. If you’re a Mac user who uses the app store exclusively and maintains high security settings you may be able to get away without one. All users should think about using an antivirus program to shield themselves from attack from phishing.
