Martin got some threatening emails and they have disappeared. Is it possible to recall an email? Leo says only if both parties are using the same program like Microsoft Outlook. The program can then connect to the other and recall and delete it. But that's really the only way. Is there any way to get the emails back for evidence? Leo says that's a good question. Martin's ISP may have a copy on its servers and exchange servers need to be involved. But Leo says that the email may still be on Martin's computer. Check the trash folder, spam folder, Chances are, she still has it.

Peter was looking for video codecs and he got bit by some malware called "Search Donkey." Leo says that even legitimate sites can get bit by malware. And places like CNet will install adware in their installer without really drawing attention to it. Leo says that the only difference between Malware and Adware is that Adware lets the user uninstall and technically gives an opt out on installation (if the user can find it).

Cheryl wants to know how to use social media to reach the most people. Leo says that most social media is set up that most won't hear her unless they follow her. So she'll have to build an audience. She can't expect to be heard by the masses automatically -- she'll have to generate interest. Leo says that a blog or a podcast are good options so she can own a place on the net and get her message out. Then she can use social media as an offshoot of that.
