The most reliable antivirus software will provide strong malware protection as well as a variety of other cybersecurity protections, and exceptional performance across all operating systems. It should be light on your computer so that it doesn’t cause slowdowns or even crash.
Traditional antivirus programs scanned for viruses by scrutinizing files as they were written to disk on the device or downloaded from the internet. If a file was suspicious, the software would block or delete it, preventing the spread of malware. The software was effective in fighting viruses that were common but as the amount of malware threats that were new grew quickly over the past decade, older antivirus tools were unable to recognize new threats and stop them from causing damage.
Antivirus replacements, also sometimes called EDR (Enterprise Endpoint Detection and Response) solutions, utilize a full set of protection technologies to detect and block everything from common malware to new attacks that have never been observed before. This approach has been proven to be more efficient than traditional antivirus programs which rely on signature-based detection.
You need to use your computer and possess an adequate level of common sense before you can decide if you require an anti-virus program. A quality antivirus program is necessary if you browse sites that are not safe, download pirated programs, or don’t have any other form of cybersecurity protection. If you’re a Mac user that only uses the app store and keeps your security high, you might be able to get by without one. However, every user should at a minimum consider purchasing an antivirus tool to protect against attacks from phishing.
