Be sure to have a good anti-virus program installed on your computer and have a firewall in place to protect your computer network. Be savvy about what you download when you are on the computer. Only download items that you are sure are from trustworthy sources. Donít open suspicious emails; simply put them in the trash. Anytime you see a file in an email or on a web page with an extension on it such as Document.exe, be wary of clicking on it and downloading whatever is on it.
Sometimes, these emails can come from people in your contact list. You might be tempted to trust an email from a friend, but it is possible that the friend has been hacked.

If you are unsure if an email is unsafe, create a new email and ask your friend if they sent the email or if they have been hacked.
