Spam has been sent from my Yahoo account to the people in my address book. I found the sent emails in the Trash Folder. I have scanned my PC using McAfee and a full scan with Malwarebytes but neither tool detected anything. As far as I can tell this occurence has not repeated (well since last night anyway). the emails each included 10 recepients and I think there were about 20 in total. Each email contained a one line link to a website. examples of those links are as follows: hxxp://yhibitybo.lookseekpages.com/ojipes.html hxxp://tasuzycite.bigheadhosting.net/ifypog.html hxxp://kihozuvud.greatnow.com/qufuri.html hxxp://ifivirolun.1accesshost.com/hijuzot.html How can I find and remove the culprit? Thanks
