User Defned Surface - storing repeatedly used variables

I am writing a user defined surface DLL, and want to know if I can speed up the DLL by storing specific precomputed values in FIXED_DATA4 or FIXED_DATA5 datasurf values. In my DLL I have several variables (a1, a2, a3 etc) which are affected by the curvature, conic constant, and one of my surface parameters (which will not vary during optimisation). The sag of the surface is a function in x and y, with different powers of x and y multiplied by these variables. eg. a1*x + a2*x*y + ... I may be misunderstanding how the DLL works, but I currently expect that each time it is called it will compute my variables (a1,a2 etc) and then calculate the sag, meaning that it is inefficiently repeating the same calculations many times, where I only need to compute the sag from the variables which are fixed during any raytracing and optimisation. Can I add code on initialisation to store the curvature, conic constant, and param[1] to the data surf values as well as the corresponding variables a1 etc, a

Malwarebytes flagged RIHWSTY31.DLL as malware.

Why did Malwarebytes flag and quarantine RIHWSTY31.DLL as malware?  See attached screensnap.  Is it a valid DLL or did malware somehow get attached to OpticStudio?  Need to know whether to keep in quarantine or release it. Thanks, Mike
