System proxy keeps changing, probably malware, how to remove?

[delirein]

I wasn't using any proxy to begin with, my PC is Lenovo Y510p laptop, with geniune Windows 8.1 and licensed Eset Smart Security. Recently I have noticed that my proxy is set to "http=127.0.0.1:8080;https=127.0.0.1:8080", and Firefox is set to use the system proxy. Trying to disable system proxy does not have any effect, the settings are back every time. Made full scan with Eset and ADWCleaner, nothing detected. What can I do?

 

 

Since the IP 127.0.0.1 is the IP Diagnostic Responder and points to your PC, it isn't using a Proxy Server, but a software on the PC is acting as a Proxy Agent.
 
I suggest seeking assistance in the Malware Removal Help sub-forum.

 

I'm posting it in this forum, asking for help. Malwarebytes Free hasn't detected anything. I am also attaching FRST logs.

What else can I do to get rid of this problem?

I did all of the above, ADWCleaner and MBAM again haven't detected anything. I noticed, that laptop is freezing recently - I had to force the reboot 3 times today - it is not overheating, though.

I am attaching all needed logs to this post, too.

Also, Firefox doesn't use the proxy, IE and all the applications (Steam, Origin, etc) does, and the proxy itself does not respond (the localhost one). I recently uninstalled Hola addon for Firefox, maybe there lies the issue?

[delirein]

I think I resolved the problem. Just some dumb registry entry blocking proxy settings from changing. Please close this topic.

OK will close out shortly, run the following to clean up...

 

Download "Delfix by Xplode" and save it to your desktop.

 

Or use the following if first link is down:

 

"Delfix link mirror"

 

Double Click to start the program. If you are using Vista or higher, please right-click and choose run as administrator

 

Make Sure the following items are checked:

 

 

• 
  

    Remove disinfection tools

 

Now click on "Run" and wait patiently until the tool has completed.

 

The tool will create a log when it has completed. We don't need you to post this.

 

Any remnant files/logs from tools we have used can be deleted…

 

Thanks,

 

Kevin....
