caused system instability
SMProxyTrace4 in temp. files will not let you select all files for deleting. You have to do each one manually. There are other files possibly associated with it that are, hysperfdata_Owner and a~DF45B5.tmp that keeps changing. If you are having problems running %temp% and cannot delete I suspect you are having spyware or other problems such as I am.
from earthlink, and causes some applications not to be able to access the internet
RedLight DLL
Whenever I end the process in Windows Task Manager, it cancels the internet connection and then the SMProxy.exe resets itself.
I work for earthlink/embarq, this product is definitely ours, and is safe, it is a part of your Total Access Browser
It's associated with Kid Patrol by earthlink. It's a total pain and seems like a virus to me. I've tried to quarantine it but when I do, I lose access to Internet (mail/browser).
Sorry, Kerry, I totally disagree. As far as I'm concerned, this is a pice of malware. Each time I've removed it, I lose connection to email/Internet, same as Mike above. I've spent / wasted HOURS of time trying to remove smproxy.exe permanently and solve the connection problem

smproxy causes an error message to appear on screen, which says "firefox has encountered an error and needs to close". there is a link in that box for more info. the error given is smproxy. so smproxy is causing firefox to shut down. there is no way to delete it or uninstall it. not even in add/remove in control panel. the file does not exist there. it is a file in the windows folder only, but cannot be deleted. when I attempt to, a message says "access is denied".

Best practices for resolving smproxy issues

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