Steps to scan malware
The malware scanning process involves tools and techniques which includes Heuristics-based malware detection, Signature-Based Detection, Sandbox, and Removal Tools.
The antimalware software examines the files and gathers the source code of the files to identify if it has a malware signature. The collected code is then passed on to the database which contains the archived virus signatures. If the identified malicious code matches to any of the malware codes in the database, then the file is malicious. The antimalware is used to delete the identified threat. This method is called Signature-based detection as it uses the archived virus signatures to compare and identify if the file is a threat. However, updating the database with the latest malware is challenging. Therefore, to identify that the malware which is yet to be discovered, anti-malware experts use heuristics mechanism. This scans the file to check for behavioural patterns to identify if the file is malware. The anti-malware creates a virtual environment called the Sandbox – the suspicious files are sent to the sandbox. The unknown suspicious files are kept in the sandboxed environment until it receives the verdict. Once the file is identified as malware it is removed using malware removal tools.
