How to Fix Emproxy.exe Problem

The emproxy.exe process belongs to McAfee Email Proxy service. This process is used by the McAfee VirusScan tool to scan incoming and outgoing emails.

File Information

The emproxy.exe file is found in C:\PROGRAM FILES\COMMON FILES\McAfee\EmProxy\emproxy.exe folder by default. You can use the program on Windows NT, 2000, 2003, XP, or Vista operating systems.

Emproxy.exe Problems

Emproxy.exe is known to consume high CPU resources, which may, at times, exceed 100%. This dramatically slows down the PC and is a cause of frustration for many users.

Cause of the Error

A possible cause of the problem may be the use of NetZero or another P2P program along with McAfee. Using old and outdated McAfee versions are also known to cause the problem.

Resolution Methods

If you would like to be free of emproxy concerns, here are a few methods you may want to try to resolve your issues.

Method 1: Disable McAfee Email Protection

Use the following steps to first disable and then re-enable McAfee Email Protection feature:

  1. Double-click on the McAfee M icon in the system tray to bring up the McAfee Security Center window.
  2. Click Email and IM and then click Configure.
  3. Select Off
  4. Now, click on Start and go to Run.
  5. Enter services.msc to display the Service window.
  6. Search for and double-click the McAfee E-mail Proxy Service.
  7. On the General tab of the displayed properties dialog box, set Startup Type to Automatic.
  8. Click Stop and then click Start.
  9. Next, display the Recovery tab.
  10. Here, set First Failure, Second Failure and Subsequent Failures options
    to Restart the Service from the combo box.
  11. Click Apply and then OK to save your settings and exit the dialog box.
  12. Open McAfee Security Center again and click Email and IM.
  13. Click Configure and then select On for Email Protection.

Method 2: Completely Uninstall and then Reinstall McAfee

Problems may occur if there are issues with McAfee files. So, if the first method does not work, uninstall McAfee completely from your system and then reinstall it. Here are the steps:

  1. Open Add or Remove Programs from the Control Panel or by running the appwiz.cpl command.
  2. Remove all McAfee products installed on your PC. Note: As McAfee is a large software product, it might leave behind some files and registry entries. This is the reason why it is recommended that you use an efficient program uninstaller tool, such as Perfect Uninstaller to completely remove McAfee products from your PC. You may also use a robust registry tool to clean your registry and get rid of any left behind McAfee keys.
  3. Restart your PC.
  4. In Windows Explorer, perform a search for McAfee and delete any files and folders that may appear in results-delete even if McAfee folders are empty. Pay special attention to “C:\Document and Settings\\Application Data” on Windows XP and “C:\Program Data\McAfee” in Vista. Note: Ensure that Windows Explorer is configured to show All Hidden Files and Folders.
  5. Reboot and reinstall McAfee.

Method 3: Disable NTRConnect from Startup

If you have NTRConnect, perform the following steps to disable it:

  1. Go to Start and click Run.
  2. Type msconfig and press the OK button to display the System Configuration Utility.
  3. Open the Services tab.
  4. Click the Manufacturer column to arrange the column alphabetically and then search for Net Transmit and Receive.
  5. Clear the NTRConnect check box.
  6. Click OK and reboot.

Note: NTRConnect is a software program that enables you to access your Windows computer from anywhere.

Method 4: Update your McAfee Product

Upgrade to McAfee 2008. This version does not have the emproxy bug.

Method 5: Switch to Another Security Tool

A last ditch resort would be to switch from McAfee to another antivirus tool suite that offers good protection without hogging too much of your CPU’s resources.
