Many of my friends have informed me that my Facebook sent them invites to join groups independent of my action?

Is this some sort of virus or a setting on facebook I can change?

no you can definitely change it its when you set up groups it asks if they can have permissionto post... just change it on facebook.

Many accounts have been stolen by hackers making false FB pages and tricking people into giving their login info. They then log into the account, and may or may not change the password, and may send messages linking to malware. Once that's reported, FB disables the account.

Always make sure you're really trying to login to FB, not a spoofed site.

Change your password, if you think someone else has accessed it.

If the notifications are coming from applications that you use on FB, edit their settings on this page: http://www.facebook.com/editapps.php?ref=mb

Change your password immediately, just in case your account has been hacked, and especially if you are not a member of the groups for which your friends have received invitations.
