my other half has felt the need to use facebook spy 1.0 how do I block this app
Block or change your other half.
Hopefully it came from here,
Publisher's description From Facebook Spy :
Open your boyfriend or girlfriend profile. Copy the facebook URL or profile ID.Paste the URL or ID in the application and done! Facebook Spy will loop each public friend of your boyfriend / girlfriend looking for wall posts, free gifts and photos where he was tagged.
Sound like trust issues to me, anyway
Hopefully uninstall it from add/remove programs
you can also block it by going to D+, my blocked files, and add it there. You can add the while folder for the program there.
