It's malware but easy to remove ...

Download and run the adware removal tool here > The Safe Mac » Adware Removal Guide

Easy, safe, and only takes a minute or two.

This has also been happening to me along with a lot more random lag.

Keep us posted 🙂

I haven't found a good Malware removal tool.

That's because there are no good malware removal tools. You have to change the way you use the computer so you don't get infected with malware. Downloading any unknown application at the behest of a stranger on a website is not a step in the right direction.

You may have inadvertently installed adware. Eradicating it is simple. For an explanation or how this may have occurred, how to avoid it in the future, and for one possible solution read How to install adware.

If that does not describe your problem please post a representative screenshot of the anomaly:

Screenshots (Mac):

To take a screenshot hold ⌘ Shift 4 to create a selection crosshair. Click and hold while you drag the crosshair over the area you wish to capture and then release the mouse or trackpad. You will hear a "camera shutter" sound. This will deposit a screenshot named "Screen Shot...." followed by a date and time on your Desktop.

When you post your response, click the "camera" icon above the text field:

This will display a dialog box which enables you to choose the screenshot file (remember it's on your Desktop) and click the Insert Image button. If you are not using full screen mode you can simply drag the image into the text entry field.

⌘ Shift 4 and then pressing the space bar captures the frontmost window.

⌘ Shift 3 captures the entire screen.

Don't capture or upload any information you consider personal. To edit an existing screenshot, read How to edit a screenshot.

Drag the screenshot to the Trash after you post your reply.

You haven't even scratched the surface of solving the problem unless you make changes in your use of the computer.

You're welcome.

The Apple moderators would not allow that.
