Big white square on sites webpage

Since yesterday I'm getting a big white square at the to of Major Geeks webpage - any comments on how to fix,

 

Looks like a popup for malware that might have been neutered.

You could try a restore point and see if whatever you have is now gone.

Yf it is still there, then you need to go to the malware section of the forum

When you have all the MGTools downloaded, run them and have the required logs, then you can start a new thread and post as attachments here

Never mind, the box is gone now.

 

I did not see your thread. Thanks for letting me know what was going on. I never saw it - lots of blockers on my browser.

 

What Browser are you using? If it is Internet Explorer are you using and security add-ons in the your browser?
Things like Avast Online Security running in IE Browser will cause a white box on the side where the Adds are here at Major Geeks Forums where it says Trending or Links. Disabling the add-on Avast Online Security in the IE Browser will cause the white box to go away. Not sure what other browser add-ons can cause this. But then your white box was at the top and not the side.
Just a thought as for something to look for in your add-ons if you have any.

Of course plodr would know more about Malware then me if that is your problem.
