A month ago our Yahoo mail account began emailing all our contacts in our address book. The emails were showing up in our sent items folder. We removed all our contacts from the Yahoo address book. We ran all the scans we could: Malwarebytes, SuperAntiSpyware, Hijack This, etc. as well as full scan on Norton without anything found. We recently created a new Yahoo mail account and added a few fake addresses to our contact list to see if anything popped back as undeliverable -- nothing did for weeks. At that point we felt that the new account was probably safe and copied all our previous contacts into the new account. Yikes, today it began trying to send emails to 20+ people again (I only saw them because they wound up in our drafts folder somehow). Please help, I think this computer has a hidden virus or bot or malware. Any help greatly appreciated.
