Kerish Doctor nailed 6 zero-day variants on my honeypot today. I sent the files to the major honeypots and only 2-3 products detected it. I now make it a point to have Kerish on all of my personal systems. It's very light, keeps things tidy, and prevents situations that can cause Windows errors. But it is very nice to see it picking up malware, especially extremely new. One of the threats had Crypto 2.0 buried in it, so this was an important detection.
Kerish Doctor software originates from Russia, from my understanding. I've seen other poor translations there previously but most have been fixed.
Yes, it's roots are in Russia. And older days its level of effectiveness was very low, have no idea about current one. Also, majority of its verdicts are based on file's names.
