I'm sorry, I don't have any of that info. Tor doesn't log to a file in
my setup. And I removed the unwanted binary file as soon as my antivirus

My antivirus program found the installer exe in the root of the drive
where the Program Files are. Tor has its folder there. A said, there was
no sign that it had unpacked.
An alternative scenario is that the detection of FTPCentre.13.A is not

this pc now and then. I can't preclude that some new software came
bundled with the backdoor program, which remained undetected untill
