Hi all, I am a Mac newbie and recently infected by a contact by just previewing an email that has (No Subject) in the title bar. After which the virus spam my yahoo contacts and send a copy of the same email to everyone on my contacts. I would need the community advice on: 1) Will this email affect my Mac? Do I need to download an anti-virus program and do a scan? If yes, which anti-virus program is recommended? 2) How to deal with the virus on yahoo email? I hope not to go the extreme of creating another new email account. But I have just changed my password and disable all preview option. Your kind advice is much appreciated. Thank you.
