The Ultimate Guide to Corporate Cyber Security Trojans often are spread via an infected email attachment or a download that hides in free games, applications, movies or greeting cards. Your computer will often slow down due to a Trojan. A Computer Worm is a program that self-replicates and spread through networks. They are transmitted through attachment, file-sharing networks and links. They consume large amounts of memory or bandwidth and the network servers will often stop responding because of them. Rootkit is a program that allows hackers to have administrative access to your computer. It can be installed through commercial security products or third-party app extensions. Detecting rootkit-like behavior can be tedious work.

The Difference Between a Computer Virus, Worm and Trojan Horse It is important to note that a virus cannot be spread without a human action, (such as running an infected program) to keep it going. Because a virus is spread by human action people will unknowingly continue the spread of a computer virus by sharing infecting files or sending emails with viruses as attachments in the email. Fast Facts: Attaches to an executable file, requires human action to spread.

Portable Software Portable software is a software program that can be run on different computers running different operating systems with no or little modifications. The Latin word “port” means to carry. Portability is the attribute of being easy to carry from one point to another or, in this case, from one operating system to another. Typically, software is said to be portable when it is more cost efficient to exchange it between two different platforms than to write the program from scratch.

Distributed computing Distributed computing is a field of computer science that studies distributed systems. A distributed system is a model in which components located on networked computers communicate and coordinate their actions by passing messages. The components interact with each other in order to achieve a common goal. Three significant characteristics of distributed systems are: concurrency of components, lack of a global clock, and independent failure of components. Examples of distributed systems vary from SOA-based systems to massively multiplayer online games to peer-to-peer applications. A computer program that runs in a distributed system is called a distributed program, and distributed programming is the process of writing such programs. There are many alternatives for the message passing mechanism, including pure HTTP, RPC-like connectors and message queues. [citation needed]

- EXE (executable) files, such as basecamp.exe, are files that contain step-by-step instructions that a computer follows to carry out a function. When you double-click an EXE file, your computer automatically executes these instructions designed by a software developer (eg. GARMIN Corp.) to run a program (eg.

What is a Computer Virus? In more technical terms, a computer virus is a type of malicious code or program written to alter the way a computer operates and that is designed to spread from one computer to another. A virus operates by inserting or attaching itself to a legitimate program or document that supports macros in order to execute its code.

program Oracle Application Testing Suite. In computing, a program is a specific set of ordered operations for a computer to perform. In the modern computer that John von Neumann outlined in 1945, the program contains a one-at-a-time sequence of instructions that the computer follows. Typically, the program is put into a storage area accessible to the computer. The computer gets one instruction and performs it and then gets the next instruction. The storage area or memory can also contain the data that the instruction operates on.

- • This self-replication property is what distinguishes computer viruses from other kinds of malware, such as logic bombs.• Another distinguishing property of a virus is that replication requires some type of user assistance, such as clicking on an email attachment or sharing a USB drive.

Computer program A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler can derive machine code—a form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter.

What is a computer virus? It’s persistently nasty, keeps you from functioning normally and often requires something powerful to get rid of it. A computer virus is very similar. Designed to relentlessly replicate, computer viruses infect your programs and files, alter the way your computer operates or stop it from working altogether. It’s estimated that the Conficker virus infected more than 10 million computers in 2009.

- Anatomy of a Virus. Though most computer users have learned to fear viruses, few really know what they are. Viruses are programs that replicate themselves inside a computer. The malicious bug cannot do its damage when a user simply surfs the Web or opens a plain text message such as an e-mail. However, viruses are unleashed when they are hidden in attachments to e-mail messages and someone opens that attachment.
