What is the difference between spyware and virus?

Spyware and viruses harm computer software or files known as malware, but spread differently. An important difference between computer spyware and virus is that spyware reduces computer activities and often sends information about a third -party user while the virus does not. Another important difference is that, unlike spyware, the virus often creates copies of itself and try to use one computer to spread the virus to others. Although both can affect computer operation negatively, spyware rarely seeks to damage the system, while viruses often cause much more lasting damage. A typical method of delivery for spyware is in the volume with other files or programs that the user decides to download. Spyware sinks into the user's system along with the required material. However, viruses are most often sprayed as attachments to e-mail or via immediate messages, although they can also be hidden in the material downloaded.

Although both can damage the computer, another difference between spyware and virus is found in the primary purpose of malware. Spyware is designed to record your computer's activities and transmit this information to a third party. It can monitor human computer's habits and transmit information to advertisers and others. Another more dangerous use can steal private information such as e-mail addresses, passwords, credit card numbers and other important personal information and give it to hacker or identity thieves.

The primary purpose of the virus is to copy and spread. It is often replicated several times, using computer sources and causing system failure. Another common virus tactic is the access-mail directory of the computer and send your copies to all addresses. It can also try to use other transmission methods where one computer communicates with another, for example when sharing files and quick sending messages. Spyware is not considered a copy or transmitted to other computersthe infected system.

Another difference between spyware and virus includes the author's intention. Spyware author usually wants to collect information that will be used for different purposes. Spyware needs an operating system to achieve it rarely damages the computer, even if it uses computer funds and can secure it slower. Viruses are often written with more destructive intentions and often make computer systems and networks unusable. After spreading, viruses often cause permanent damage to the operating system and hardware.
