Using BT Virus Protect to check your computer for viruses

If you've accidentally opened or downloaded a suspicious file, you should now download anti-virus software and complete a full scan of your computers.

If you already have BT Virus Protect or want to use another anti-virus checker we recommend using either McAfee Stinger for PC or Sophos Antivirus for Mac. Both are free to use. Visit their websites for more help.
