What is an antivirus?
An antivirus is a type of software that detects, prevents, and eliminates dangerous software (malware) on computers and other devices. It scans files and programs for known dangerous code patterns while also monitoring program behavior in real time to detect suspicious activities that may signal the existence of malware. Antivirus software is critical in safeguarding devices and data against online threats such as viruses, worms, Trojans, spyware, ransomware, and others.
Examples Of Computer Threats
1. Viruses: These are dangerous programs that connect to and infect other files on a computer. Once a virus-infected file is run, it can propagate to other files and cause system damage. For example, a virus may erase files or corrupt data on the infected computer.
2. Worms: Worms are self-replicating malware that spreads over networks and computers without the need to attach to files. They use vulnerabilities in network protocols or operating systems to spread from one device to another. For example, a worm could propagate via email attachments or by exploiting software security holes.
3. Trojans: named after the Greek story of the Trojan horse, are malware disguised as legal software. Users may accidentally download and install Trojans, believing they are safe programs. Trojans, once installed, can carry out a variety of destructive operations, including stealing sensitive information, spying on user activities, and granting the attacker illegal access. For example, a Trojan masquerading as a game program might steal login details.
4. Spyware: is a type of software that secretly monitors and collects information about a user’s computer or device activity. This information may include keystrokes, internet history, login credentials, and so on. The captured data is often routed to distant servers controlled by the attacker. One kind of spyware is a program that monitors a user’s internet browsing activities and communicates the information to advertising without the user’s knowledge.
5. Ransomware: is a sort of software that encrypts files on a victim’s computer or device and makes them unavailable. The attacker then demands payment (ransom) from the victim in exchange for decrypting the files. Phishing emails and malware downloads are common methods for spreading ransomware. Ransomware might be a malware that encrypts all of a user’s papers and demands payment in Bitcoin to decrypt them.
How Antivirus Software Works:
Antivirus software works through two ways namely Signature Detection and behavior detection.
Signature Detection:
Antivirus software recognizes specific diseases by signature detection, in the same way your immune system does. It examines your computer for features or signatures linked with known harmful apps.it identifies Patterns by referring to a vocabulary of known malware. If it discovers a match, the program tries to neutralize the threat. This technique, like flu vaccines, requires frequent upgrades to fight against emerging malware strains. However, it can only guard against what it already knows.
Behavior Detection
Behavior-based antivirus uses software behavior to detect malware, rather than relying on known threats. When a software acts suspiciously (for example, accessing protected files or changing other programs), it generates an alert.
This strategy prevents new, dictionary-less malware. However, it is important to note that it may generate false alarms. Users might become desensitized to all those warnings over time.
