mEMBERS IN MY ADDRESS BOOK ARE GETTING EMAIL SUPPOSEDLY FROM ME?
I allowed Linkedin to search my yahoo address book for possible expansion. Since I did that hundreds of emails have been sent to these people from my address. How do I stop this since those in my book will just stop taking emails from me?

Are they emails about LinkedIn? If so, go into your account on LinkedIn and look through your settings.
If they are not emails about LinkedIn, it may just be spam. If this is the case, it’s probably just a coincidence. Change your Yahoo password, and dont let your computer save the password. Go to download.com and install malwarebytes, run this and your Antivirus program. If still nothing, someone hacked your email. Let me know how this goes, and good luck!
