Antivirus, also called as anti-virus, software program, or pc application, is a certain type of computer software intended to stop, detect and take away malicious computer system programs out of a computer. The word “antivirus” derives from the malware itself, which is an application that spreads through computers slowing down them. The term “anti-virus” was first used in 1982 by experts involved in the study of information protection. They gave the term “anti-virus” to avoid any association with computer viruses themselves. In more recent years, antivirus software is growing to include various other security equipment such as anti-spyware and spyware and adware.
There are two basic types of antivirus security software programs, free-ware and shareware. Free applications are prepared for free, and shareware applications are purchased and so are usually provided by commercial or perhaps other warranties. Freeware antivirus programs could be categorized generally into computer virus, spyware, ad ware and malware. These three programs work in tandem to detect, end, and clean malicious codes from your computer, as well as to maintain and run numerous utilities just like email, conversation, and MSN & Aol! messenger.
There are other types of antivirus software built to protect against unique forms of or spyware and malware. Some are aimed at protecting against malware while others are designed to protect against trojans that can destruction or eliminate a system (viruses, malware, spyware). There are even ant-virus programs which will scan your entire computer for any infections that have not really been discovered by your current antivirus. These kind of protection are made to protect happened only from malware but also word error by phishing scams and via the internet attacks.
