I am very sorry to see that PD Creator, although an open source software (which for me is synonymous with "safety") continues to install malware during installation of the latest versions.
Fortunately my antivirus ESET NOD32 detects it, but others do not, thus making it less secure than their PC.
Since this policy continues to PDF Forge, stop using PDF Creator and also stop recommending it to my customers.
The offending file is as follows: OCSetupHlp.dll
The virus / malware is as follows: Win32/OpenCandy
I contacted ESET has confirmed that this is NOT a false positive, but a real threat.
