The advent of technology has led us, humans, to lead a digital life. Such a life brings with it a set of problems and one such problem is cybersecurity. The threat from the Internet and other sources is one of the essential aspects that one must consider before looking out for a antivirus software.

One of the most common types of malware in the cyber world is the spyware. It downloads to your computing device and spies on your computer activities. It acquires all the sensitive information from your computer. The malicious software program gets attached to the emails or the web pages that you visit on a regular basis.

It is important to understand the difference between virus and malware. All viruses are essentially malware but all malware do not necessarily have to be viruses. However, the term virus is more frequently and widely used by people. The different types of malware besides virus are a worm, spyware, adware, Trojan horse, bot, bug, ransomware, rootkit, dialers, keyloggers, rogue security software, and malicious BHOs.

Trojan or the Trojan horse virus is a malicious and highly dangerous computer program that deceives a computer user. It enters a system or network by pretending to be something normal. It gets its name from the wooden Trojan horse that was used in Greece in ancient time to enter the city of Troy and for destroying it.

Firewall is a network security system which controls the outgoing and incoming of online traffic and protects the system from unethical sources and access. It works as a barrier between ethical, known users and unethical, fraudulent hackers. The firewall installed in a PC is one of the most important network security systems that protect the functioning of your computer.

Computers have made people’s lives a lot easier. Whether it is maintaining customer’s details in a bank or updating the track records of students in a school, everything can be done in a jiffy. As computers are used for handling financial, personal, and confidential data, it is important to install a trusted and reliable antivirus software to prevent the laptop or PC from hackers.
