 Adware is a type of malicious software that secretly installs itself on your device and displays unwanted advertisements and pop-ups. In some cases, adware can even track your online behavior and display personalized ads. Adware is short for advertising supported software, designed to throw advertisements up on your screen, most often within a web browser. Some security professionals view it as the forerunner of the modern-day PUP (potentially unwanted program). Typically, it uses an underhanded method to either disguise itself as legitimate, or piggyback on another program to trick you into installing it on your PC, tablet, or mobile device. Adware is unwanted software designed to throw advertisements up on your screen. “Adware is unwanted software designed to throw advertisements up on your screen.” Here’s how it happens. You go online with your nice, well-behaved browser, only to see it fly into a virtual tantrum, as an onslaught of advertisements either pops up, slides in from...

A file-infecting virus is a form of malicious software (malware) that attaches itself to real executable files on a computer. When the infected file is executed, the virus is active and runs with the intended program, spreading to other executable files and performing its harmful actions. What is a File-Infecting Virus? A file-infecting virus is a type of malware that, as its name suggests, infects files on a computer. It inserts malicious code into the files it targets, which can include executable files (.exe), dynamic link library files (.dll), and sometimes documents. When an infected file is opened or executed, the virus code is run, leading to various potential outcomes depending on the virus's intent. How is the File Infector Virus spread?  File Sharing and Downloads: Infected files can be shared via email attachments, peer-to-peer (P2P) networks, file-sharing services, and other online platforms. Users directly download and open these infected files, leading to the spread o...

 When it comes to strengthening cybersecurity and protecting your digital data, you must be able to recognise a few more names and terms than what you already know about the digital risks and dangers, a specific one being “computer viruses”. So, before we dive into the definitions of boot sector virus, it’s imperative to understand how a basic virus works and what it is. In simple terms, a virus is a malicious program that tries to disrupt a normal computing operation by spreading its infectious codes into different executable files of the hijacked system. By multiplying itself, the creator of that virus can secure vulnerabilities and proceed with their intentions of extracting private information, gaining admin control, and similar spiteful purposes. Viruses are usually transmitted through defective online software, websites, emails, links, etc., and occasionally, by infected outside drives. Recently, however, cybercriminals have been involved in the increased practice of physical...

 Chances are you’ve heard how important it is to keep viruses out, but what is a computer virus exactly? A computer virus is a type of malicious software, or malware, that spreads between computers and causes damage to data and software.  Computer viruses aim to disrupt systems, cause major operational issues, and result in data loss and leakage. A key thing to know about computer viruses is that they are designed to spread across programs and systems. Computer viruses typically attach to an executable host file, which results in their viral codes executing when a file is opened. The code then spreads from the document or software it is attached to via networks, drives, file-sharing programs, or infected email attachments. Chances are you’ve heard how important it is to keep viruses out, but what is a computer virus exactly? A computer virus will more than likely have an adverse effect on the device it resides on and may be discoverable through common signs of performance loss...

 Pre-Requisite: Basics of Computer A computer is an electronic device that has storage, computations, input (data), output (data) and networking capabilities. With the growing AI, computers also have learning capabilities from the data provided. The input and output data can be in different forms like text, images, audio and video. A computer processes the input according to the set of instructions provided to it by the user and gives the desired output. Computers are of various types and they can be categorized in two ways on the basis of size and on the basis of data handling capabilities.Types of Computer There are two bases on which we can define the types of computers. We will discuss the type of computers on the basis of size and data handling capabilities. We will discuss each type of computer in detail. Let’s see first what are the types of computers. Super Computer Mainframe computer Mini Computer Workstation Computer Personal Computer (PC) Server Computer Analog Computer ...

 A computer is a machine that can be programmed to automatically carry out sequences of arithmetic or logical operations (computation). Modern digital electronic computers can perform generic sets of operations known as programs. These programs enable computers to perform a wide range of tasks. The term computer system may refer to a nominally complete computer that includes the hardware, operating system, software, and peripheral equipment needed and used for full operation; or to a group of computers that are linked and function together, such as a computer network or computer cluster.

A computer is a device that accepts information (in the form of digitalized data) and manipulates it for some result based on a program, software, or sequence of instructions on how the data is to be processed. Complex computers include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer hardware (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming. Major types of computers Analog computer - represents data by measurable quantities Desktop computer - a personal computer that fits on a desk and is often used for business or gaming Digital computer - operates with numbers expressed as digits Hybrid computer - combines features of both analog and digital computers Laptop (notebook) - an easily tra...
