What is tomcat.exe?

The genuine tomcat.exe file is a software component of Tomcat Web Server by Apache Software Foundation.
Tomcat.exe is an executable file that belongs to the Tomcat Web Server, an open source web server and servlet container developed by the Apache Software Foundation. This file is not a critical Windows component and should be removed if known to cause problems. Tomcat originated as a tiny servlet reference implementation created by James Duncan Davidson, a programmer working with Sun Microsystems. Davidson helped make the project completely open source and was responsible for the project being donated from Sun Microsystems to the Apache Software Foundation. The Apache Software Foundation (ASF) is an American non-profit organization that supports Apache software projects. The ASF operates as a community of developers, distributing software that is produced under the Apache License, thereby keeping it open source and free. The organization was founded in 1999 in Delaware, USA.

Apache Tomcat Webserver. Part of many applications. Not always strictly on-line - look no further than Adaptec/PMC's maxView Storage Manager used by RAID controllers from this particular vendor for array GUI management. Don't disable it unless you're absolutely certain that there are no dependencies. Otherwise software which require it won't work. It's RAM intensive application - make sure you have enough.

Best practices for resolving tomcat issues

A clean and tidy computer is the key requirement for avoiding problems with tomcat. 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 tomcat.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. Malwarebytes Anti-Malware detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
