Most of the malware and ransomware that comes through the internet and onto our systems is thanks to email attachments. If you see an "invoice" with an artificially rushed, demanding tone from a powerful figure (such as your work boss) and they've attached a "PDF", be very skeptical and do not open it. The same goes for links, since they can take you to a very shady site. Make sure to update your computer with security patches to prevent infection from background exploit kits across the web.
Wayne got an email from a realtor about taxes in his neighbourhood. It had a PDF attachment and he can't print it. Rich says that if it's a PDF, his computer is probably opening up the file directly, without using a PDF reader. Right-click to see what options to open it with.
Leo says that Fred is right to be concerned about the security of sending emails because the contents of the messages can be read along the way. If the email is going from one Gmail address to another, however, it would be secure. Ultimately, though, Leo doesn't recommend sending attachments at all. Opening attachments is how most people end up getting infected, and it doesn't just affect that person either. It will spread to all of that person's contacts, affecting their family, business, and the internet as a whole.
Ed bought a new Mac and transferred all of his data and email accounts from his old Dell. But now he's not getting all the text of his emails. Leo says that this may be an email provider issue. Apple comes with a fully capable mail program. Leo says to go into the account settings to make sure everything is entered properly. Also, if his ISP is using POP instead of IMAP, it's downloading all of his email and then deleting it from the server. If using POP Mail, it's possible that Ed is only getting new email, not the old ones because they're gone.
Greg likes to send photos via email with Outlook and it always defaults to medium resolution. He wants to change it to a high resolution. How can he do that? Leo suggests trying to drag the image to the mail window and see if it downsizes. Another option is to avoid sending attachments altogether and send a link to the image online, like at Flickr or Google Photos. This is far more secure and he can have full resolution images online.
Peggy wants to back up her Yahoo mail using Carbonite. Leo says that Carbonite will back up a basic set of files by default. But it will back up other files if she sets it to. She'll have to do that within the Carbonite's settings.
Scott says that when using Office 365 with a mobile device, the images within the letterhead end up as attachments instead of being embedded. Leo says that inline imaging in Office365 is a convenience that Microsoft offers, but it's not a standard, and it ends up as an attachment. He can't control that. There is no fix other than to stop using images in email. The only time that an inline image is displayed is in an email reader that supports it, and he can't control what people use. Email is designed for people to use text and it's just best to stop using corporate logos in emails.
John uses Gmail with the Mac Mail app, and he can't send out any images that are about 500kb. Leo says that's odd. Leo suggests going to Gmail on the web and try sending the images there. If it works, then there's a bug in Apple's Mail client.
Kevin sends his clients PDFs and he wants to know the best way to send them over the net. Leo says that sending attachments via email is a security issue and he always tells people not to open attachments from people. He recommends putting a PDF up on Google Docs or Google Drive, and then sharing a link to it. That way they can open it up in a secure environment and don't run the risk. Kevin may have to educate his clients, and that's a negative, but it would be safer to do it this way.
Leo says saving it to Skydrive is a good option and may be Microsoft's intent. That way he can access the file directly. Microsoft really doesn't want anyone to use Live Mail or Hotmail anymore, they'd rather have everyone move to Outlook.
