Computer Virus prevention


Virus prevention

  • Virus protection should be up-to-date and latest and anti-virus should be upgraded on a regular basis.
  • Virus protection is to be used to automatically scan and fix an e-mail before it is opened.
  • Automatic downloads should not be permitted by the antivirus installed in the system when a website is accessed.
  • There should be controls which permit and allow only authorized personnel to writer or alter programs. All changes must be recorded and documented and senior manager should verify these changes.
  • Programs or disks should be accepted after checking them with the latest version of anti-virus. Antivirus should automatically scan any disk inserted into the computer. If a disk is lent to any person, it should be checked before it is used again.
  • Floppy disks should not be left in the disk drive for longer than necessary time,
  • Demos or software with doubtful origins should never be used.
  • System should not be booted with a disk in the disk drive unless it is a confirmed to be a system disk which is “Clean” and bootable.
  • Delete cookie files on a regular basis or select “do not accept cookies option” in browser preferences as cookies act as agents for Trojan horse  and virus transfer.
