Toontown Mmo And Security

I was big fan of the Toontown Online MMO when Disney used to run it so I was excited to learn that it had been revived by a group of fans building on the original source code. During a recent update my virus checker said there were questions about the new installer executable, and that they were looking into it. That made me realize that although I'm usually very cautious about what I click, download, etc, in this case I didn't even think about the issue of security.

My understanding is that you can't really do real-time protection on the traffic between the server and the engine on your PC but i don't really know enough about the process to make an informed decision as to how vulnerable it might be, especially given the current smaller third party nature of the MMO. So any advice, insight, etc would be appreciated.

 

Couldn't figure out how to edit my original post so adding this as separate post.

I know this was a somewhat general question, so to update this, I do have two more specific questions that maybe someone can answer.

First, I am thinking about switching my anti-malware software to PCMatic, which I guess uses a whitelist approach instead of a blacklist approach. Would this be effective in preventing anything a hack would do from installing additional malware? And would it fail to prevent redirection to a malicious web site or would it catch it?

Second, is there some way I could use virtualization to create a sandbox that would run the program and isolate it from the rest of my system in case there are any issues? I'm in the middle of researching VPN vs virtual machines, becaue I don't truly understand the concept yet, but (assuming they're truly different things) would one or other or both allow me to do that? Or can I do the same thing by say installing Linux as a dual boot OS and use that only for TT? Or is the second OS not really isolated and thus safe?

Thanks if anyone can offer any insights on this.
