You have to stop opening up suspicious Emails
If you Email address starts with your name like e.g
honeysue12345@gmail.com then the hackers can address an E mail starting with Honey Sue
Your E mail address should be a non descriptive name like e.g
rtdwu@gmail.com
So if you get an email that says Dear rtdwu, then do NOT open it as they do not know you.
I get tons of malicious Email starting e.g invoice sent, bill due or whatver
Another thing be sure that common domain names are displayed [.doc, jpg, bmp etc], the default is hidden
So you can see if it is some .zip file or whatever do NOT open it
