I open a dropbox request and now several hundred people have received email dropbox requests from me. Your virus checker has not found anything. Have you some advice?
Could you please explain what type of email are you referring to here? What contents does the email has? And which F-Secure product are you using?
My dropbox account uses my aol address and I'm using F-secure on an MAC Airbook and also use Freedome
What are the contents of the email sent? Is it the invitation/referral email from Dropbox which is for referring friends? Then, I am guessing it might be automatic from Dropbox for the referral. You might want to check with your Dropbox settings about it.
