It is an excellent browser
I had it as my email service but lost access when MSN upgraded. I have now upgraded my Windows XP but still cannot gain access to my MSN mailbox. I love the browser and the mail service, but my experience of the last two weeks tells me their customer service is non-existent
It's running in our company and infects systems over network share with an trojan
It's part of the Verizon with MSN Premium package

It is the main program file for the popular MSN Explorer. It can be used to directly access the Address Book, or the Mail Composer of the MSN client, and even the Calendar and Favorites Manager.

Best practices for resolving msn issues

A clean and tidy computer is the key requirement for avoiding problems with msn. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
