While on holiday in Turkey I used a local bar's wireless hotspot, on returning home I noticed that an email had been sent from my BT Yahoo email account to everyone in my address book. I know it was sent from my account because it is in my sent items. The email has the subject of "More Happines" and the email is below. No more emails like this were sent before or after while using this hotspot
i introduced a good friend to you
they sell thousands of new original electrical products
such as phones computers tvs ....
hope you like it , and make friends with them too
I have checked my laptop for viruses and use Microsoft Security Essentials and also scanned my laptop with Malwarebytes.
I would like to know how they did this and how I can prevent them doing it again as I will need to use the same hotspot in the future
