I noticed today that Bloodline Champions was now also available from Steam as an free-to-play title so I decided to try it. When I was installing it, Comodo shows me a warning saying that this file (BloodlineChampionsLoader.exe) is scanned online and found malicious. I scanned that file on VirusTotal and only Comodo found that file as malicious. (Link to the scan report: http://www.virustotal.com/file-scan/report.html?id=42ae7da7bb05cca9ae04b1521e7accc7c444f0d7dcbb78dc36062737d4fcc1dd-1320501401)
I am 99% sure that this is false positive. Can you please confirm that? Here is the file (BloodlineChampionsLoader.exe) in case you need it:
