Sunbelt security has issued a warning for the ChatSend application.  It installs toolbars for all popular browsers and changes the user’s home page.  It then generates spammed messages extensively within Facebook.  It is difficult to remove once installed and should be avoided if offered by any of your Facebook contacts.

Facebook – Avoid ChatSend application

QUOTE: There’s a program called ChatSend currently doing the rounds on Facebook, and at time of writing just over 114,000 people have hit the “Like” button which no doubt means a high proportion of that tally have downloaded and installed it. The link directs to the Facebook page of ChatSend where one can readily download the app. Upon execution, it shows a GUI containing its Terms of Service and Privacy Policy. The pre-ticked boxes will install the toolbar in all browsers, set web search as default and change the homepage.
