From Legit Log:
If you are still using utilities like the very basic Notepad to view log files, then you will find a log file viewer to be a vast improvement, providing everything that you need to work with log files of just about any type. Even in the unlikely event that you find a specific log file format is unsupported, you can easily add support for it by making a minor edit in the XML configuration file. Legit Log Viewer also supports encrypted log files as well as those containing special characters using Unicode or various other encodings. The rich search, sorting and filtering capabilities make it easier than ever to quickly find the entries that you are looking for and get your work done more efficiently. You can also highlight specific entries just with a couple of clicks of the mouse.
