Weird popup... W7

Any of you ever see this before?

Every now and then, I get a pop-up-like screen. It's full browser screen, dark-translucent black with a white dialog box. The dialog box has only an "X" in the corner to close. No text, no graphics.

The two stay on the screen until I click the "X".

Malwarebytes and Kaspersky AV scans show nothing.

You're owned! Someone's using your machine as a proxy server, possibly in a botnet.

Time to wipe and reinstall.

Shouldn't be opening/clicking on things from "friends"... or porn sites... :eek:

 

Have you tried right-clicking on it and then View Source/Inspect Element/Properties?

 

Haven't yet. Will next time.

Thanks.

 

Could be. But why would such a program announce its presence?

 

Script kiddie, most likely. With a pro, such "mistakes" would be rare.

Are you using IE? I remember when I was testing some Javascript and/or iframe code, my mistakes would show up as a blank window with a red X, just like you experienced.

 

Mostly I use Pale Moon... sometimes IE, but perhaps not often enough to see it appear there.

 

Another possibility is an affiliate with a bad "onClick" or "onMouseOver" attribute in a html tag... Made that mistake a few times, too...

 

Reminds me of some of the popups to "like us" on FB... maybe it displays weirdly on mine because I don't have a FB account. ??

 

Look in Malwarebytes for any exceptions which you did not put in there.
