Just a short note on a publisher called Innovative Systems LLC. When I uploaded the Innovative Systems LLC file to VirusTotal it had a 9% detection rate. Some of anti-virus scanners calls the file InstallCore. Symantec classifies the file as Trojan.Gen.2:

According to the certificate, Innovative Systems LLC is located in Ukraine.

Did you also find a file digitally signed by Innovative Systems LLC? What kind of download was it and where did you find it?

I’ll try to follow up on this one later, to see if the other anti-virus programs adds it to their detection.
