We have a clients PC which is heavily pixelated when running flash video.
The PC was initially infected with some malware infections. However the client has noticed this issue for some time.
We have removed all the malware using ComboFix, Malwarebytes, HijackThis, Kaspersky etc.. However the fault still persists.
We have also re-installed the latest graphics card driver, fitted a different graphics card and performed a Windows XP repair install.
The effect looks as if someone is pouring molten lava over the picture. We also noticed that the ActiveX yellow security bar that appears when installing something like Flash, causes IE to freeze. Finally we also tried a different Web Browser and the effect is still the same
Any help would be greatfully appreciated.
