I am now getting what my partner got: "C:\PROGRA~2\WINCERT\WIN32C~1.DLL is either not designed to run on Windows or it contains an error. Try installing the programe again using the original installation media or contact your system administrator or the software vendor for support." If you press the OK button it stays put as it's in a continuous loop but if you press the X to close it, you get several messages: igfxtray.exe - bad image (in every case it says "bad image" so I won't waste time typing this) igfxpers.exe GoogleUpdate.exe SearchEngineProtection.exe sidebar.exe MUIStartMenu exe QLBCTRL.exe etc all the programmes that are attached to the start menu are listed every time you press the X key. I ran Malwarebytes and it found countless PUP registry faults which I quarantined. Any suggestions would be gratefully received. I managed to backup my photographs and other important documents and will continue doing so tomorrow.
