Be careful what you download

It can be easy to simply allow a download to go ahead on your device, especially if you think the source appears reputable. Be wary of any files that you download and question their authenticity before confirming the download. This is particularly pertinent for email attachments — where the sender may look legit, but could not be — and things like apps, which invariably redirect you to an app store to install them. If an app download begins immediately, without redirecting, this should be a red flag.
