You stated it was "a direct download from the GOM Player website". GomLab offers two download sites. One being CNET and the other brothersoft. Did you download it from CNET?
I did. And I scanned it with three different scanners. All the files were reported as clean. Try downloading it from CNET here. At one time, the GOM Player came bundled with the ASK Toolbar. Whether it still does, I don't know. I also don't think it's relevant to what AAW reported.
I would suggest downloading it from the above CNET link. If AAW continues to detect it as a Trojan, I would then upload the "gomwiz.exe" to VirusTotal. If VirusTotal reports it clean, I would then report it to Lavasoft. It could be a false reading on AAW's part.
Let us know how you make out..
I have downloaded a "GOM player" and two Trojans came hidden in the GOM program file: Partial "Ad-Aware Scan-Log", follows:

The player was a direct download from the GOM Player web site; Microsoft, Security Essentials, found another two Trojans, but missed those 'provided' by GOM Player.
Someone at CNet should go to the web-sites themselves and check the software
