The first malware programs merely looked for any digital unsecured personal that would distinctly identify a virus file. For example , a scanner could search reminiscence and the start sector upon disk with respect to code clips that are typically found only in viruses (not in not cancerous programs). The program then even comes close these to the existing list of malware to determine whether it is dangerous.
Classic antivirus software still uses these signature-based strategies to protect users from known threats. It means that when a new file can be downloaded, the software scans their database of signatures for your match.
