Recent update of MalwareBytes (Free Version 1.34 and Database Version 1902) reports 1) An Inno Setup.exe version 51.34.0.0 which is used to extract the compress bin files as malicious item. I have been using InnoSetup to create installation package which provides the Setup.exe version 51.34.0.0 from Inno software. I don't think it is a malware. Probable some malware may use that kind of Inno setup file to install malicious files. 2) Some registry entries of Beyon Compare Merger as malicious items. I think that also a wrong alarm. I have been using Beyon Compare Merger for a long time.
