TeraCopy 3.10 and 3.12 require AVX2 compatible processors for certain checksums

After a lot of head scratching and frustration we have discovered that TeraCopy 3.10+ will crash with certain checksum methods when the CPU in the computer does not support AVX2 instruction set. There is no warning or error messages. The application will just bomb out.

We will add AVX2 detection and fallback to SSE2 in the next version.

Could you please run this app to see if the detection is working?

Please unzip this file to Program Files\TeraCopy and check if it's working:

I was having issues with TeraCopy and thought this might be the solution. Both the diagnostic file and the patch file trigger Windows Defender as malware. 'cputest' comes back as "Wacapew.B!ml" and teracopy.exe reports as "Wacatac.B!ml" which is rather serious malware. I would love an explanation for this as neither of these infections are typical of false positives.

This version is working on my old Xeon systems with all flavors of the xxHash.

Any thoughts on when the final fix will be posted?
