saw it running and eating my processor

My computer was infected with lot of Sality viruses. And dwtrig20.exe was also infected. It was launching a shutdown countdown at startups and was blocking the Taskmanager and the Registry. (I found a way through CMD to kill this monster)

Some other sights note that viruses use it to track your site visits to tie to keylogger for you ID's and passwords.

It is a part of Dr Watson related to crashes and/or failed MS system updates from MS to send the info to find out why the System updates failed.

This file appeared during the last two MS monthly updates - never saw it before in the Process viewer. I have had system instability ever since. This is on a Windows XP SP3 machine, with Office 2003 & Windows Defender installed. This file was not on my machine before. I wonder if MS used BITS again to secretly install this software, separate from Windows updates. You can remove it from the AUTO RUN settings. This almost seems as if it is some sort of monitoring program, not related to Watson or Defender.

It only occurs in my startup if I have done a windows update and one or more of the files have failed to install and i have rebooted. After the reboot and a report is ready to send, it changes it's name to dw20.exe while waiting for a response to send the error report. After sending, it removes itself from the task manager.

Best practices for resolving dwtrig20 issues

A clean and tidy computer is the key requirement for avoiding problems with dwtrig20. 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 doing a repair of your installation, or in the case of Windows 8, 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 dwtrig20.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.
