I think DTUpdate.exe is the updater process for a browser plugin called "Default Tab". DTUpdate.exe connects to the Internet to check for updates and you might get a notification in your firewall about the outgoing connection.

If you are looking for uninstall instructions for DTUpdate.exe, there should be an entry for the "Default tab" in the Windows Control Panel or in Firefox's Extension manager. Look for entries called "Default tab" or "Search Results, LLC".

Did this answer your questions about DTUpdate.exe?

ESET NOD32 detected (and cleaned) DTUupdate.exe on my PC today.
If you call a cat's tail a leg, it still only has four. Calling a tail a leg doesn't make it one.

Firefox locked up. Malwarebytes didn't find anything, even after update definitions. Same with Ad Aware and AVG antivirus. Couldn't get into hotmail or Yahoo mail.
Finally repeatedly delved deeper into Hotmail Help. Finally the tech on there 800 # transerred me to a phone number of a firm that specializes in "debugging" problem cases. They charge you, do an install of a remote desktop of your 'puter. But charge comes later, after, if they fix your problem.
Their tech then took over my desktop and noted the "search bar" on my 'puter and stated it was a malicious install that installs some malware on you. He said this is an Indian source item that takes over your browser, a re-direct."Don't click it." I said I had various Anti-Virus products, He said, "no charge", use them. Spybot found 3 items. Claro Toolbar, W3i.IQ5.fraud, Wajam and 2 entries of PUPSC, and My Web Search (bar).
I'll now try to find way to clense Firefox of the alien toolbar.
