The most reliable antivirus software will provide strong protection against malware, a range of other security features and superior performance on all operating systems. It must also be light on your computer’s resources so it won’t slow down or crash.

The old antivirus programs scanned for viruses when files were being written to disk or downloaded from the internet. The software will either quarantine or remove a suspicious file to keep malware from spreading. The program was effective in combating viruses that were common, however, as malware threats increased rapidly over the past decade, it was unable to detect and stop them.

Antivirus replacements, also often referred to EDR (Enterprise Endpoint Detection and Response) solutions, use a full set of security tools to identify and stop everything from commodity malware to novel attacks that have never been observed before. This approach has been proven to be more effective than traditional antivirus tools which rely on signature-based detection.

You need to use your computer and possess a decent level of common sense before you determine if you are in need of an antivirus program. An antivirus program that is reliable is necessary if you browse suspicious websites, download pirated programs, or have no other cybersecurity protection. If you’re a Mac user that only uses the app store and keeps your security high you may be able to get by without one. Every user should consider installing an antivirus program to protect themselves from attack from phishing.
