Computers are everywhere in our lives. They allow us to work and play, monitor patients in hospitals, and manage critical manufacturing processes. However, this convenience comes with a cost since more devices that use computers are targets for hackers.

Antivirus protection scans programs and files to detect threats that could be present and acts as a live shield against cyberattacks. It identifies infected programs and files based on their recognizable indication – two lines assembly code that replaces the stack pointer for instance – and compares them with the database website link of known malicious software. If the program matches the database, the antivirus software will stop it from running and send it to quarantine for thorough analysis and scan.

Unfortunately, malware creators constantly create new programs with more subtle and distinct signatures. Antivirus programs must upgrade their databases. Once a virus is detected and added into the detection database hackers will have a harder time to use the same signature on different devices.

Most reliable antivirus programs include various options to guard against the wide array of malware threats. They include:
