Frequently, custom DLLs with such naming conventions are used in gaming communities for modding or creating "trainers" and cheats.

Based on available technical data, "LoserZDev.dll" does not appear to be a standard Windows system file or a widely recognized component of mainstream software. It is likely a custom-made library related to independent developer projects or community-created modifications.

If you did not intentionally install a mod or software from "LoserZDev," its presence on your system could be suspicious.
