This dll file is believed to be a trojan virus that activates your svchost.exe and eating up memory of your computer. Surprisingly it is even one of the programs allowed in the firewall settings.
Deleting .dll drivers is really not possible I think, because it is actually running in your PC, you have to disable it first to keep it from running as an application. To do that, you go to your Windows Firewall with Advance Security, go to the Inbound Rules lists..look for the file @peerdistsh.dll,-10000, right click on the file, go to properties on the menu, on the General tab, tick on Blocked the connection, then click okay. Restart the computer, and you should be fine.
