Never accidentally click on a pop-up view link. Alternatively, close the message by pressing the "X" in the upper right corner so the view link stays away from the incoming website.
If your devices do not have an antivirus , use a well-paid antivirus , which protects the personal data and information of your computer, tablet, Mac or smartphone from online threats.
Avoid clicking on any unknown URL . Whether it comes via email, social networking site, or text message, if the url link seems uninformed, stay away from it.
Beware of emails that collect personal information. If an email comes from your bank telling you to click that email link, reset your password, or access your account, don't click it. You go directly to the online banking website and log in from there.
Don't open an unknown email attachment unless you know what the email is, even if it came from an acquaintance or an unfamiliar person.
