Computers are everywhere in our lives. They help us play and work, monitor patients in hospitals, and control critical manufacturing processes. This convenience has a downside as more computer-based devices are a target for hackers.
Antivirus protection scans files and programs to identify threats effectively acting as a real-time shield against cyber-attacks. It detects infected files and programs by their telltale signature – a couple lines of assembly code that overwrite the stack pointer, for instance – and then compares them with a database of known malware. If the program matches the antivirus software, it will stop it from running, or moves it to quarantine so it can be thoroughly analyzed and scanned.
Unfortunately, malicious software creators are constantly creating new programs that have distinct and subtle signatures, which is why antivirus programs must keep updating their databases.
