Hi Rappaping,
What have we been investigating so far and to which conclusions has this investigation led us? We have been thoroughly investigating this tool with respects to its being malicious or suspicious, and this also for everything in there. I have reached the conclusion that this tool is neither suspicious and nor malicious and does not contain any malcode. Pondus has supported this through his investigations.
The functionality and the use of it should qualify this to be marked "riskware" for those first time users that are not familiar with the use of it and whenever it comes installed unto their computers without prior knowledge or consent of the user.
There is a lot of reputable software that matches the same characteristics as the one described in this thread. We mentioned some. For that group of files I would like that av solutions, that really use aggressive generic methods in their scans, will come to use a "whitelist" of tools and programs that would else be classified as FP or PUP, and now only are qualified as risktool.
Therefore the developer of such tools and software should sign their software accordingly to make it stand apart from malware clones or malicious counterparts, that normally cannot have these signatures. I think you could install now, I think this thread has shown it is free of malware,
