Emsisoft Firewall BLOCKING My Router & Slowing My Ethernet


Recommended Posts

Lets try getting a log from FRST, and see if it shows the cause of the issue. Please download Farbar Recovery Scan Tool (FRST) from one of the following links, and save it to your Desktop (please note that some web browsers will automatically save all downloads in your Downloads folder, so in those cases please move the download to your desktop):

For 32-bit (x86) editions of Windows:

For 64-bit (x64) editions of Windows: Note: You need to run the version compatible with your computer. If you are not sure which version applies to your computer, then download both of them and try to run them. Only one of them will run on your computer, and that will be the right version.
  • Run the FRST download that works on your computer (for Windows Vista, Windows 7, and Windows 8 please right-click on the file and select Run as administrator).
  • When the tool opens click Yes for the disclaimer in order to continue using FRST.
  • Press the Scan button.
  • When the scan is done, it will save a log as a Text Document named FRST in the same place the tool was run from (if you had saved FRST on your desktop, then the FRST log will be saved there).
  • Please attach the FRST log file to a reply using the More Reply Options button to the lower-right of where you type in your reply to access the attachment controls.
  • The first time the FRST tool is run it saves another log (a Text Document named Addition - also located in the same place as the FRST tool was run from). Please also attach that log file along with the FRST log file to your reply.

I experienced the same broken-and-slow Internet connection issues after first installing Emsisoft Internet Security, and I noticed that turning off the EIS firewall component fully restored the reliability and speed of my Internet connection.


I used Revo Uninstaller to uninstall EIS, then I reinstalled EIS -- but that provided no improvement.  The EIS firewall component continued to eratically slow my Internet connection.


I had previously been a very happy Emsisoft Anti-Malware user, so this EIS experience was especially surprising to me.


I found guidance in the EIS KnowledgeBase about using EmsiClean to fully uninstall Emsisoft products.


I repeated the Revo Uninstaller removal of my second install of EIS and followed it up with EmsiClean, which removed a Registry entry shown to be for EAM's configuration, "HKEY_LOCAL_MACHINE\Software\Emsi Software GmbH\a-squared".  My EmsiClean log file is attached, in case it is useful to Emsi Support Staff.


I reinstalled EIS, and the broken-and-slow Internet connection issues were totally gone.


Good luck!

The FRST log shows a Poweliks infection. Lets try the ESET Poweliks Cleaner, as it should be able to safely remove the infection. You can download it from this link.

Here's some instructions for running the ESET Poweliks Cleaner:

  • Please run the "ESETPoweliksCleaner" download if you haven't done so already.
  • Read the terms of the "End-User License Agreement" and click 'Agree' if you agree to them.
  • The tool will run automatically. If the cleaner finds a Poweliks infection, press the 'Y' key on your keyboard to remove it.
  • If Poweliks was detected "Win32/Poweliks was successfully removed from your system" will be displayed. Press any key to exit the tool and restart your PC.
  • The tool will produce a log in the same directory the tool was run from.
  • Please attach the log to a reply so that I can take a look at it.
For reference, here's a link to a picture of what it will look like when a Poweliks infection has been detected:


And here's a link to a picture of what it will look like when Poweliks has been removed from your computer:

OK, go ahead and get me an updated log from FRST so that I can verify that Poweliks was indeed cleaned up completely. Please be sure that the option for Addition.txt is selected before running the scan in FRST.

That's looking much better. I'm only seeing a few things in your latest FRST logs that could be considered "Potentially Unwanted". If you'd like to get rid of those things, then here's instructions on what to do:

Please download the following fixlist.txt file and save it to the Desktop:


NOTE: It's important that both files, the FRST download from earlier and the fixlist file, are in the same location or the fix will not work. If you need to, please copy the files from your Downloads folder to your desktop.

  • Run the FRST download from earlier, and press the Fix button just once and wait.
  • If for some reason the tool needs to restart your computer, please make sure you let the computer restart normally. After that let the tool complete anything it still needs to do.
  • When finished FRST will generate a log on the Desktop (Fixlog). Please attach it to a reply.
