Antivirus How To
Installing antivirus software is one of the most important cybersecurity tips we can offer, but many people don’t know where to start. Don’t worry; we’ve got it covered.
If antivirus is new to you, that’s okay. Start with our basic guides.
To summarize, antivirus software detects and neutralizes malware, which is malicious software. Typically, antivirus software scans an entire device and all of its files for suspicious behaviors. This means that it can detect viruses and malware even if they’re not in any database yet.
By looking for behaviors rather than signatures, antivirus software can even detect malware that organizations like AV Labs don’t yet know about. All of the antivirus software we’ve tested has behavior-based detection, which is superior to signature-based detection, which finds only known malware.
