Hi Auri,
There will almost certainly be errors in the mojo log and the Event Viewer > Application log on the machine but most errors are handled and logged and don't cause any big problems. Lots of scripts out there purposely poking at sites to cause errors.
The strange error I got after the recent windows update was way down in the runtime not in mojoPortal code, a fragment from my og is:
System.TypeInitializationException: The type initializer for 'System.Drawing.ToolboxBitmapAttribute' threw an exception. ---> System.Runtime.InteropServices.ExternalException: GDI+ is not properly initialized (internal GDI+ error).
at System.Drawing.Bitmap..ctor(Stream stream)
at System.Drawing.ToolboxBitmapAttribute..cctor()
--- End of inner exception stack trace ---
at System.Reflection.CustomAttribute._CreateCaObject(Void* pModule, Void* pCtor, Byte** ppBlob, Byte* pEndBlob, Int32* pcNamedArgs)
at System.Reflection.CustomAttribute.CreateCaObject(Module module, RuntimeMethodHandle ctor, IntPtr& blob, IntPtr blobEnd, Int32& namedArgs)

googleing it led me to this post

which led me to this post:

which sounds like a problem that was previously patched by Microsoft but perhaps was patched again recently.
I had never seen this error before and knock on wood have not seen it again since rebooting.
I've added your site to the list, thanks!
Best,
