My youngest wants to download and install Battle of the Immortals from Perfect World.
I was suspicious straight away as it was installing games like this that caused problems on the kid's computer earlier this year - strange browser toolbars and the like being the most obvious ones. We've since reinstalled Windows and I'd like to keep the machine clean.
I've found a forum thread here that claims the game contains a trojan, but it's couched in language that makes me think of conspiracy theorists and doesn't offer any hard evidence. Also as Lee points out in his comment there isn't going to be any out-and-out malware in there. It's more the "extra" toolbars etc. that I'm sure will be included in the install that I'm worried about.
I'd like to be sure that I'm not going to let him install anything nasty onto their computer. I can obviously scan the exe before I run it, but that won't tell me if it installs any browser plugins etc. What else can I, and should I, check?
