Various antivirus software are designed to protect your computer or device from malware, viruses, and other malicious threats. They work by scanning your system for potential threats and either removing or quarantining them. Here are some common types of antivirus software:

  1. Signature-based antivirus: This type of antivirus uses a database of known malware signatures to detect and remove threats. It compares files and programs on your system with the signatures in its database. If a match is found, the antivirus takes appropriate action. 
  1. Heuristic-based antivirus: These antivirus programs use behavioral analysis to identify potential threats. They analyze the behavior of files and programs and look for suspicious activities or patterns. Heuristic-based antivirus is effective at detecting new and unknown malware that may not have a specific signature yet.
  2. Cloud-based antivirus: These antivirus solutions leverage the power of cloud computing to analyze files and detect threats. Instead of relying solely on local resources, they send files to a cloud server for analysis. This allows for faster scanning and real-time updates to protect against emerging threats.
  3. Behavior-based antivirus: This type of antivirus focuses on monitoring the behavior of programs and processes on your system. It looks for unusual or suspicious behavior that may indicate the presence of malware. Behavior-based antivirus can detect and block threats that don't have specific signatures.
  4. Sandbox antivirus: Sandbox antivirus creates a virtual environment to run files and programs in isolation. It allows potentially malicious files to execute in a controlled environment where their behavior can be observed. If a file exhibits malicious behavior, it is contained within the sandbox, preventing it from affecting the rest of the system.
