The Detect Shellcode Injections in Image Execution Control Settings in Defense+ is the Buffer Overflow Protection that was incorporated into CIS to take the place of the stand-alone Comodo Memory Firewall. Executables that were hogging CPU resources could be very effectively added to the CMF Exclusions list to drastically reduce excess CPU usage. The Detect Shellcode Injections has this same Exclusions option. Just add stacsv.exe as an exclusion and see if that doesn’t take care of your excess CPU problem. Back when I had CMF installed, prior to this last CIS Beta, which incorporated Buffer Overflow Protection into CIS, I had to add two or three executables into the CMF Exclusions list to keep CPU usage from getting extremely high. This worked very effectively for me. But since CIS incorporated Buffer Overflow Protection, I have not had to add any executables into the Exclusions list. But that would be the first thing I would try if I found an executable hogging CPU resources.
