Part of CA Arcserve Backup, stayed after Arcserve removed. Disabled it.
Can be prevented from running by disabling Event Log Watch service

simply end task on lic98service.exe and then rename the CA folder and re-install the product

Installed w/ CA software for Licencing; doesn't uninstall when sftwr removed
This file might be essetial for programms using it, so remember what you do! If you do not know just give it a try disabling it. Preventing the process from starting can be performed with standard window's tools. Registry hacking, manually editing is not necessary. You can go to the "services" and *SIMPLY STOP IT* and change the start options. Type to prompt: "mmc services.msc" (just tried on XP), lookup "Event Log Watch" (deutsch: "Ereignisprotokoll-Ɯberwachung") and change the state. See taskmanager to confirm the vanishing of the process "LogWatNT.exe".
Part CA/Etrust; lingers so at command prompt: sc delete logwatch
Still after installation (and following removing) ERWin

Best practices for resolving LogWatNT issues

A clean and tidy computer is the key requirement for avoiding problems with LogWatNT. 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.

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.
