Anti-virus software
A virus is a program, usually disguised as something tempting or harmless or hidden within other programs, that when activated can corrupt or delete data. Viruses are designed to spread very easily through email or portable storage media, such as floppy disks.
There is a wide range of anti-virus software that can be purchased to protect data from loss or corruption. All of them scan incoming and outgoing files for known traits of viruses and can be programmed to delete or quarantine offending files.
But as new viruses are regularly emerging, it is imperative that any anti-virus software is regularly updated so that the new virus traits can be detected. Most anti-virus programs can be automatically updated via the manufacturer’s web site. An update at least once a week is recommended.
The main virus scanners are from Symantec, Norton, Vet, McAfee and Watch Dog.
