• Avoid provide file shares to others. Apply strong password policy if it is unavoidable. If you are using Windows XP, disable the simple file sharing.
• Apply strong password to protect you machine. Do not leave administrator password blank or assigning trivial password with your Windows machine.
• Avoid referring, storing or copying files (programs and documents) from unknown or untrusted source such as download from Internet or email attachments received from friends.
