Offliner-A-GoGo: Sorry, I have an issue regarding your program GOGPlus Download Checker v2.4:
When I unpack the zip file with 7zip I see a error message ("Warning:There are some data after the end of the payload data"). If I use winRAR, it is ok. After all, it is no exe file located in the unpacked folder! Windows Defender delete it instantly.
It sounds like your AV is causing the issue.
Offliner-A-GoGo: With VirusTotal I get 3 findings from 3 engines.
And nothing am I right, from all the other engines?
So in reality you have three false positives, which is a regular occurrence with programs created with AutoIt.
Some AV are a bit slow at keeping up-to-date, with Windows Defender often being one of those.
Offliner-A-GoGo: I would like to use the program. What can I do (or could you do something)?
If you got a lot more than 3 findings, then I'd be worried. But as it is only three, I would either wait a few days, until Windows Defender at least, is no longer giving a false positive, or you can do as I do, and just add an exception for
GOGPlus Download Checker.exe in your AV.
Unfortunately, this is often a matter of timing, and you've been affected, whilst many other downloaders haven't been, or you would see their posts in this thread and or at GitHub. So if you are troubled about trusting me, just consider that, and I wouldn't want to tarnish my reputation with GOG, considering how many games I have bought from them, so there is that too.
Cheers!
P.S. If you do make it an exception in your AV, and you still get an unzip error, I would be concerned that something may have infected or corrupted the file, somewhere on its journey from me to you. I extracted my copy with 7-Zip without issue.
