Welcome to the forum.
Well, that can be False Positive... or we should never forget that any file can be poisoned by 3rd party or downloaded from the wrong place, etc.
"trojan-downloader.17876" - that is most likely not a precise detection name.
You typed it ... there could be mistake(s) in file name too
That's why it is recommended saving report and copy/paste it (or extraction) here.
The location of the files / precise names of files and/or Registry Entries ; processes, etc. are required. The same applies to the detections names.
In order to investigate the matter if you are not sure, first it is better submitting items detected to EMSI (“Submit as false alert”) from the detection list before quarantining
But there are methods of rechecking (“Re-Scan”) after you placed something into jail.
Please read the following link. In the reply from Thursday, 25 December under “submitting and or auto-rescanning” there are helpful references about different ways to do that.
I hope you will learn how to investigate, submit detected items, setting Re-Scan option, etc…. e.g.: “How should I treat the malware I found?”http://forum.emsisoft.com/Default.aspx?g=posts&t=4220
I checked the link you posted, but in the future please don't post links to the files/software in question unless you were asked to do so.
First, that doesn't add a lot. Nobody will download / install the Software at the same time if that is infectious site that can be harmful to other users.
Only analysis of the code of that particular file present on your computer can give an answer. And that can be done only by EMSI developers
