How does antivirus software identify potential viruses? Antivirus software scans the files and code coming in and comparing them with a database of known malware. These databases are continuously updated and allow antivirus programs to identify new threats swiftly.
The most popular method by which an antivirus program recognizes a virus is to look at its digital fingerprint, or signature. Each virus has its own unique digital fingerprint that sets it apart from other programs and files. The signature is created by comparing particular parts of the virus’s code against the database of known viruses, and then flagging it if there is a match. Antivirus scanners may also use heuristic analysis to look at the behavior of a file or the characteristics that are suspicious. This will look at patterns or trends of a webroot reviews com file that could indicate it’s an infection, for instance deletion of large amounts of data, observing keys that are constrained or remotely connecting to equipment.
Some antivirus programs use the sandboxing feature in addition to the signature-based or heuristic method of detection. Sandboxing allows viruses to run in a virtual setting and observe how it acts so that the scanner can see if it is doing what it’s supposed to do. If the virus is detected and quarantined, it can be removed immediately and removed from the system.
