Don't worry, guys, there's no trojan there. :) Pretty much all anti-virus software nowadays uses heuristic (a.k.a. "smart", "intelligent" etc.) scanners, which sometimes detect code that resembles that of a virus, but actually isn't one. This is called a "false positive" and is most definitely the case with ToEE's executable. Please ignore any warning messages and, preferably, whitelist the file or disable your anti-virus software before launching the game.
Now, if you can't find the executable after installing the game, then your anti-virus software most likely deleted or quarantined that file. In that case, reinstall the game, but this time make sure your anti-virus software is disabled during the installation so that this doesn't happen again. Disabling real-time scanning while you play the game may be needed as well.
We apologize for the trouble and we'll see what we can do about making those scanners stop panicking... ;)
Update: We have released a new version of the installer, which includes a modified executable. This should minimize the number of anti-virus scanners that throw false positive warnings to a few less popular ones. Depending on the user feedback, we may make some further modifications to the executable.
