Trojan.PWS.Siggen2.34627 in ccsetup563.exe ?

[CZ69 0]

Virustotal detects a trojan in ccsetup563.exe: DrWeb: Trojan.PWS.Siggen2.34627

Windows 10 SmartScreen filter shows a warning, too (see screenshots).

Any ideas?

Yes, it's a false positive. It usually happens after every release. It should be fixed in a day or two, Microsoft will have to update the filter.

Only 1 flag out of 67 A/V providers on VirusTotal is a good indication that it's a false positive.
