Computers are all around us in our lives, from helping us play and work to monitoring hospital patients and regulating critical manufacturing processes. This ease of use has a drawback since more devices that use computers are a target for malicious coders.
Antivirus protection scans programs and files to detect potential threats, essentially acting as a real-time shield against cyber attacks. It detects infected programs and files using a distinct sign – two lines of assembly code overwriting the stack pointer for instance and compares them against a database of known malicious software. If the program matches the database, the antivirus program will stop it from running and move it to quarantine for a thorough scan and analysis.
