Antivirus software is a security tool that protects your device from malware, viruses, ransomware, spyware, and other online threats. It works in real time by scanning files, downloads, and system processes to detect and remove malicious activity before it causes damage.
Continuously monitors files and system activity to block threats instantly
Performs full system scans to detect hidden or advanced threats
Removes malware without damaging your system or important files
We test each antivirus for at least 60 days across multiple devices and real-world scenarios. Here is our full testing methodology:
We test with 1,000+ real malware samples using independent labs such as AV-Test and AV-Comparatives. A top antivirus should achieve a detection rate above 99.5%.
We measure CPU, RAM usage, and system performance during scans. A good antivirus should use less than 10% CPU and have minimal impact on performance.
We check how often safe files are incorrectly flagged as threats. Fewer than 5 false positives per week is considered acceptable.
We evaluate extra features such as firewall, built-in VPN, password manager, banking protection, parental controls, and overall security tools.
