Thank you for bringing this to our attention!
It seems the Program we use to obfuscate (encrypt) our code was abused by someone making viruses or the anti-virus companys simply didn't like the fact, that obfuscated code is very hard to analyze! But we can assure you that the F-Tool.exe doesn't contain any harmful code.
We checked against backup copies of the F-Tool on our harddisks and there was no manipulation of our webserver therefore we are convinced that its the original file without any malware in it.
We will also release the Source of the F-Tool! So that everyone can build their own version of it
