tmp warning in SCJ dashboard

[Gradwank]

"Quick scj folder check returns warnings
/usr/home/xxxxxx/xxxxxxxx.com/www/scj/bin/89aefb7ee32484c644f1d28a3e073aed is not in tmp folders list, and not on permissions list, skipping, check file manually !"

I have this error about 6 times on home - what is causing it?

those files shouldn't be there.
Run update, delete those file and let me know if it appears there again.
