Big red screen

I cannot figure out how to remove the big red danger screen off my computer. I can push it off to the side, but I want it removed. Any suggestions.

 

Hi gilby,
Welcome to Major Geeks!

Please go to Removing Zlob aka SmitFraud, SpySheriff, Infections and follow the instructions. This will produce two logs, both called Rapport.txt. Before you do the cleaning part of the instructions, please attach the first rapport.txt here, so it doesn't get overwritten by the second rapport.txt. Alternatively, use the save as feature to give it the name rapport1.txt

After you complete that, please continue with the instructions in the READ & RUN ME FIRST and attach the requested logs.

Thanks.
