Every time I use ESS 3.0.621.0's on demand scanner to scan this file, it crashes my whole system and I have to reboot. The file is AVSredirect.dll and it is associated with FFmpeg and avisynth. I have been able to scan this file with Norton and Sophos and they both do not indicate it as a virus; however, it would be nice for ESS to be able to finish a manual scan without crashing. I have contacted technical support about this issue and I am waiting for a response. In the mean time, could someone download this file and verify this problem? I placed the dll in a password protected zip file so it won't crash the real-time scanner. The password is "password" without quotes. Download file here.
