_trinity.dll is a file used with the Macrovision Ltd. game Eve Online.
Many users have reported slow connections and even system crashes while playing Eve Online and some other games by Macrovision Ltd. (which also makes Battlefield 2 and at least one of the Harry Potter games, among other things).
You may want to check and see if the version of the game you bought is pirated or not, as Macrovision uses copy-protection software on their games. Pirated copies are usually the cause of any crash or slowness with this company’s games. However, no software is perfect, and this has been known to happen with registered copies of the games as well.
The offending files of these protective programs are often .dll files. .dll files operate in the Windows registry. This registry is the main path through which operational files move.
The registry keeps operational files bundled together so as to not bog down the computer or the operating system. However, it too can become cluttered because of damaged files, viruses, programs that don’t uninstall properly, and simple usage over time.
A scan and cleanup with a registry cleaner can bring a compute back to its top speed. ZookaWare PC Cleaner offers a free scan to anyone who feels that there computer has slowed down.
