Trend Micro Server Protect or OfficeScan. It can use a lot of RAM (all of it)
yes it is part of Trend Micro office scan. Yes it does keep urlhist.txt. If it's an office machine you probably signed or accepted an AUP saying nothing you do on that machine is private anyways. Leave it on or risk getting a virus/malware that makes url tracking the least of your concerns
Trend Micro Office Scan  
Yes, Trend Micro - but CPU-usage sometimes at 80% (together with NTRTSCAN.EXE and PCCNTMON.EXE)
Logging what you are doing everywhere. See urlhist.txt in trend micro folder
Trend Micro Updater

Best practices for resolving TmListen issues

A clean and tidy computer is the key requirement for avoiding problems with TmListen. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic 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 resmon 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 DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the TmListen.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan.
