Malware is considered among the most severe form of cyberattacks that specifically targets to destroy or obtain unauthorized access to a computer system. Most of such malware is self-replicating in nature. They infect a system and infect all the systems attached to it in the network. It works at a very fast rate.


A worm enters a device when a user executes any vulnerable network application. This application can receive “malware” from the web and execute it. In this way, a worm is created.


Phishing is the commonest type of network attack. It is done by sending emails pretending to come from known resources and creates an urgency to let users act upon it. These emails contain malicious attachments or links and may even probe you to share their confidential information.
