Computers are omnipresent in our lives, from assisting us play and work to monitoring patients in hospitals and controlling critical manufacturing processes. However, this ease of use comes with one drawback, as computers are a bigger chance for malicious coders.

Antivirus protection scans programs and files to identify threats and acts as a real-time defense against cyberattacks. It detects infected files and programs by their telltale signature – a couple of lines of assembly code that modify the stack pointer, for example and compares them to the database of malware that is known to be infected. If the program is found to match the database, the antivirus program will stop it from running and send it to quarantine for a thorough scan and analysis.

Unfortunately, the creators of malicious software are constantly creating new programs with distinctive and more subtle signatures, which is why antivirus programs have to constantly update their databases. The good news is that once a virus is discovered and added to the database of detection, it becomes more difficult for hackers to apply that same signature against other machines.

To that end, the most good antivirus programs come with a number of additional features to help guard against a greater variety of malware threats. These include:
