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.

The second approach is called heuristic analysis. Such analysis may include data captures, port monitoring and other methods.
Most commercial antivirus software uses both of these approaches, with an emphasis on the virus dictionary approach.

CompactbyteAV (CAV) Version 0.94

This is an antivirus for local Indonesian viruses/worms. It is not meant to replace existing antivirus products. Most Indonesian viruses/worms spreads through USB disk at small Internet Cafes, and not through network/Internet, so if you live outside Indonesia it is a bit unlikely you will get these viruses/worms. Most of the local Indonesian virus are not detected by Commercial AV for weeks or event months. It seems that there are no incentive for the AV companies to prioritize these viruses, since Indonesia is known to be the one largest Intellectual Property Violators (in other words, there are very few Indonesian customers).

You should check your computer using the latest update of your antivirus software, before trying this program.
