Antivirus software are computer programs that attempt to identify, neutralize or eliminate malicious software. The term "antivirus" is used because the earliest examples were designed exclusively to combat computer viruses; however most modern antivirus software is now designed to combat a wide range of threats, including worms, phishing attacks, rootkits, trojan horses and other malware. Antivirus software typically uses two different approaches to accomplish this:
- examining (scanning) files to look for known viruses matching definitions in a virus dictionary, and
- identifying suspicious behavior from any computer program which might indicate infection.
Most commercial antivirus software uses both of these approaches, with an emphasis on the virus dictionary approach. Some people consider network firewalls to be a type of antivirus software, however this is not correct.
Free antivirus software can protect your computer without you having to pay a large price for software purchase or download. This free antivirus software should protect your computer from all forms of viruses and prevent the entry of anything that will damage your internal and external systems. Keep in mind however, that free antivirus software still comes at a price. And the price is being unsure as to the quality and effectiveness of the software. Reputable computer and software manufacturers all offer their own variety of antivirus software available for purchase.
