It shows this message when you start Opera: "A third party application that is not compatible with the DEP (Data Execution Prevention) security feature has tried to attach to Opera. This application poses a security risk, so it is strongly recommended that you update it, or remove the application if no fix is available. The incompatible module was: C:\Program Files\Common Files\Microsoft Shared\INK\SKCHUI.DLL".
It's MS office handwriting input - you can uninstall it from office setup , go to shared featues / alternative user input / hand writing and uninstall it. Opera web browser will throw up a security error until you get rid of this file and its only needed if you're using handwriting input. Apparently it gets exploited by some viruses.
