Something keeps setting Proxy Server to 127.0.0.1:8655 when i boot

Hello

My daughter has just bought a brand new HP Windows 10 laptop. She has hardly browsed to anywhere other than google or microsoft but after only a day there were problems browsing the internet. Her Internet Proxy settings were wrong. "Automatically Detect Settings" had been turned off and "Manual Proxy Settings" were on and set to 127.0.0.1:8655. I turned them back to automatic and then browsing worked fine. However when i reboot they are set back again. I have been into the registry and deleted HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Internet Settings\ProxyServer and set  HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Internet Settings\ProxyEnable to 0 but a reboot just sets the registry values back again.

 

I ran malwarebytes scan which found a trojan  c:\Users\{Name}\AppData\Roaming\temp.exe which i successfully removed and i also removed some adware files. This didn't make any difference though when i rebooted.

 

Does this sound like something the trojan has done before i removed it, or is it something maybe the trial mcafee anti-virus software is doing? Please help me, my daughter is very upset as she has spent a lot of money on it and thinks she has broken it already.

Hello Kevin

Thank you for your reply. I hope I have attached the correct logs. For the malwarebytes scan i have attached 2 logs. The first one was when i removed the trojan after the first scan, the second one was when i removed the adware files after the second scan. 

Further info, although i don't know if this is related, i left the laptop on overnight to install a windows feature update (it has already successfully installed several security updates) and install a new version of the trial mcafee anti-virus software. Both of these failed by not being able to connect to the servers although the proxy setting was still automatic and i was still able to browse and download your scanning tool ok this morning.

thanks...

Thanks for those logs rml123, continue:

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Open Malwarebytes Anti-Malware.
 
  • On the Settings tab > Protection Scroll to and make sure the following are selected:
    Scan for Rootkits
    Scan within Archives
     
  • Scroll further to Potential Threat Protection make sure the following are set as follows:
    Potentially Unwanted Programs (PUP`s) set as :- Always detect PUP`s (recommended)
    Potentially Unwanted Modifications (PUM`s) set as :- Alwaysdetect PUM`s (recommended)
     
  • Click on the Scan make sure Threat Scan is selected,
  • A Threat Scan will begin.
  • When the scan is complete if anything is found make sure that the first checkbox at the top is checked (that will automatically check all detected items), then click on the Quarantine Selected Tab
  • If asked to restart your computer to complete the removal, please do so
  • When complete click on Export Summary after deletion (bottom-left corner) and select Copy to Clipboard.
  • Wait for the prompt to restart the computer to appear, then click on Yes.
  • After the restart once you are back at your desktop, open MBAM once more to retrieve the log.


To get the log from Malwarebytes do the following:
 
  • Click on the Reports tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Clean button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download Microsoft's " Malicious Software Removal Tool" and save direct to the desktop

Hi Kevin

Many thanks for the detailed response. Please find attached the requested files. (log3 is the malwarebytes threat scan log).

Without trying to tempt fate I think this has done the trick. I had a peek at the proxy server settings after each restart and automatic was on with no sign of the manual server setting coming back. The FRST fix appears to have done the work. Furthermore the windows update has kicked into life and is now "preparing to install updates 43%"

I will await your response to the log files before regarding the issue as resolved but thank you for your help it is very much appreciated. For future reference what are your thoughts on what caused this? Was it the trojan that i removed yesterday that caused the pain and is this likely to have come from something that was browsed after the laptop was purchased?

thanks again

Richard.

Yes logs look good, unless you have any remaining issues or concerns we can clean up....

Infections are really a serious threat for any PC. Infections usually gets delivered via any of the following:

  • spam emails,
  • bundled freeware programs
  • Drive by downloads.
  • When browsing exploited websites
  • Exploited USB drives
  • Exploited Router
  • Exploited Social Media

They can make several malignant activities on your system after gaining accesss to your computer. Some of the harmful doings are:

  • Disable your security
  • Inject and start malicious processes/services
  • Slow down your computer speed.
  • Bring other harmful threats and malware.
  • Make unwanted changes in registry settings.
  • Steal your personal and confidential data.
  • Create a backdoor into your computer system.

Next,

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

Or use the following if first link is down:

"Delfix link mirror"

If your security program alerts to Delfix either, accept the alert or turn your security off.

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 <----- this will remove tools we may have used.
  • Purge System Restore <--- this will remove all previous and possibly exploited restore points, a new point relative to system status at present will be created.
  • Reset system settings <--- this will reset any system settings back to default that were changed either by us during cleansing or malware/infection


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…
