I have tried downloading both the torrented file, and from the Cleveland server. Both come back as infected with Win32:Malware-gen. That was detected by Avast. I switched over to my laptop, which uses Microsoft Security, and it detected the same thing. So I can't download the game client, unless both my anti-virus suites are being overly cautious.

Yes, it's being overly cautious. As mentioned on the above thread, I reported the false positive to Avast, but I don't really have a lot of expectation of them changing anything.

If you upgraded to Linux, you would eliminate this problem and not have to deal with Windows.
