The mentioned Flash downloader might contain ransomware that tries to encrypt your hard drive. I am not 100% sure, but since this was the last executable that was installed on my PC, the probability is very high. The encryption starts from svchost.exe as soon as the system is idle for 15-30 minutes. The mentioned file does not need to be started, the installation process seems to be enough.
