Adware or PUA ( potential unwanted application ) is of course a huge difference from real genuine Malware.
From my own thorough test on this software, I got Zero malicious detection even if I can confirm for example that PDFRunningHelper.exe get's installed, but there's still no malicious connection from that one specific and all it does is help, open the main software faster. Too many other software does the exact same with modules and features that also get's installed/used in the background.
Personal reflection on this, is that Kaspersky's assessment in their view when it comes to PUA or Adware in a majority is correct, but it also feels very sensitive ( possible too much ) in this specific case and that AV's block or flag/warn even 100% genuine legit software and their behavior, ain't anything new. Personal if I used this software and had Kaspersky on my machine and got this blocked, I would simply consider exclude the software in the AV.
