Antivirus software program, sometimes categorised as anti-virus, is mostly a program used by many computer systems to protect the pc system via viruses, spyware, malware, and other harmful applications. A computer is a great unforeseen virus that enters a computer program through free, shareware, or perhaps free downloading. The contamination could have a different sort of program or perhaps it may demand a download of one more file, for example a game or music data file.

Free-ware is not really free, thus there is always the chance that someone could publish a disease into a totally free program.
