Undetected Nop Function?

[Braco22]

Is there an undetected nop function for CA? Mine keeps getting detected.

This is the one I'm using.

bool Memory( void * pDest, char * szPatch, size_t sSize )
{

    DWORD dwOrgProtect = NULL; 
    if ( !VirtualProtect ( pDest, sSize, PAGE_EXECUTE_READWRITE, &dwOrgProtect ))
        return FALSE;

    memcpy( pDest, szPatch, sSize ); 
    VirtualProtect( pDest, sSize, dwOrgProtect, NULL ); 
    return TRUE; 
}
