DO — ask Why
Did you expect to see a pop-up? Pop-ups from trusted sources generally only happen when the user has requested to download a file from the website.
DON'T - Immediately click
Pop-ups that occur from selecting other links are generally not safe. Your bank, insurance company, or medical provider will not utilize pop-ups on their site unless you have requested to download a file.
Avoid clicking on pop-ups, especially if they are unexpected and be sure to update your anti-virus software on your computers and devices.
If ever in doubt, contact 888-331-6521.
