Suspicious Link - warnings in emails

All my emails with links in them from reputable senders have this red warning box slap in the middle. I can’t move it or close it. This is becoming a right pain. How do you get rid of it

Are you using web based email, or a local email client? If web based, it sounds like you may have the Link Guard feature enabled in the Safe Web browser extension. Click on the Safe Web icon to the right of the browser address bar and then click on the settings gear icon. Then turn off the Link Guard feature and see if your email links are still being flagged.
