Considering ufasoft hasn't released the new source and the recent virus warnings, i would start thinking that he is the one spreading the botnet.
He was asked many times in this thread and he just ignored the requests(didn't even bother answering). I don't really need the source, but if he is spreading the botnet, it's very likely the current exe to be "infected" as well.
1. As you can see ufasoft.com has other business. It is a software development. And the domain ufasoft.com registered more than 10 years.
2. Risk of reputation loss don't allow any long-time shareware developer to embed any backdoor to his software.
Botnet creators always are anonymous.
3. Source code of latest version for Linux will be provided after testing of build process.
4. Binary for Windows with CUDA support will be provided during a week.
5. I have a few time to answer repeating questions about antiviruses, so mostly I ignore them.
