Malware

Malicious software (malware) is software developed to interfere with a computer system. Viruses and worms are two examples of the best known malware but there are many others. Malware is a which is short for malicious (meaning malicious and non malicious) and software (software). Because viruses were historically the first malware, the term "virus" is often used improperly, especially by the media to describe all sorts of malware. Antivirus software supports this abuse since its objective was never limited to viruses. Malware should not be confused with defective software, that is to say a program that is intended for a legitimate purpose, but it has bugs or errors in behavior caused by programming errors or design software. (In this case, then it is a riskware). Some malware are not detected by your anti virus. Viruses and worms are both capable of replicating. They can generate copies of themselves, sometimes with slight modifications. However, all programs that replicate themselves are not necessarily viruses or worms. For example, software can be copied to other media as part of system protection. To be classified as a virus or worm, it is necessary that at least some of these copies can be replicated in their turn.
