Strange pictures embeded in browser

Hi all, I was hoping that someone could offer some advice on a strange problem my laptop is having.

My browser has suddenly started to embed what looks like peoples profile pictures from social networks everywhere. For example, the backgroud of Ebay has become a tiled random profile picture. Also, favicons and other icons have also become strange pictures. This problem only seems to be present when I use firefox. I have run virus scans with Avast and Malwarebytes but both have found nothing.

Thanks.

Does this occur when you run firefox in safe mode https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode

I tried safe mode but the problem still persists in safe mode.

Could you follow the steps here http://forum.avast.com/index.php?topic=53253.0

I have attached the report from AdwCleaner.

Did you create this reg file ? C:\ProgramData\bymospdtnwwknlbvose.reg

Clear Cache/Temp Files
Download TFC by OldTimer to your desktop

[*] Please double-click TFC.exe to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
[*]It will close all programs when run, so make sure you have saved all your work before you begin.
[*]Click the Start button to begin the process. Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two. Let it run uninterrupted to completion.
[*]Once it’s finished it should reboot your machine. If it does not, please manually reboot the machine yourself to ensure a complete clean.

I ran TFC and the problem now seems to have gone. Thank you for your assistance.

All problems cleared then ? It was probably an errant java script in the cache
