Installing PDFCreater v2.5.3 triggers anti-virus warnings

I downloaded version 2.5.3 fro the website today (8/4/17). During installation ESET antivirus reported op.exe is a variant of Win32/WebCompanion. I selected the Disconnect option and the install continued.

Does PDFCreator replace op.exe? and if so how can a legitimate file be identified?

Thanks for your assistance.


the op.exe is actually our component, which is responsible for displaying an offer screen during the setup of the freeware edition. While it is totally safe and will not cause any harm or install the offers without consent, blocking it will also not cause any problems with the installation and no further action needs to be taken.

Best regards,
