G+ is still in the testing phase so its not open to the general public as of now. But if you're eager to join G+ better get an invite from anywhere. But be careful as there are a lot of scams going on, a lot of fake invites are being sent or posted in the web by cyber criminals.
The fake invite contains an infected link that when accessed, redirects the user to a very common Brazilian Trojan banker file – a .cmd file hosted at Dropbox. The most interesting thing to note in this message however is another link pointing to a form hosted at Google Docs. The message shows the link as “send the invitation to your friends” but it is actually a fake form created to collect names and e-mail addresses of new victims. Kaspersky Lab has reported this malicious file and the fake Web form to Google for their interest.
