255.255.255.255 outbound being blocked

Recommended Posts

I keep receiving a popup from MB that tells me that svchost.exe is being blocked trying to connect to a website.  It lists the IP address as 255.255.255.255.

255.255.255.255, port 68, Outbound Connection, C:Windows\System32\svhost.exe.

Hello Denrich and welcome to Malwarebytes,

My screen name is kevinf80, i`m here to help clean up your system. Make sure to run all scans from accounts with Administrator status, continue as follows please:

Anyone other than the original starter of this thread please DO NOT follow the instructions and advice posted as replies here, my help and advice is NOT related to your system and will probably cause more harm than good...

Change the download folder setting in the Default Browser only. so all of the tools we may use are saved to the Desktop:

Google Chrome - Click the "Customize and control Google Chrome" button in the upper right-corner of the browser. Choose Settings. at the bottom of the screen click the "Show advanced settings..." link. Scroll down to find the Downloads section and click the Change... button. Select your desktop and click OK.

Mozilla Firefox - Click the "Open Menu" button in the upper right-corner of the browser. Choose Options. In the downloads section, click the Browse button, click on the Desktop folder and the click the "Select Folder" button. Click OK to get out of the Options menu.

Internet Explorer - Click the Tools menu in the upper right-corner of the browser. Select View downloads. Select the Options link in the lower left of the window. Click Browse and select the Desktop and then choose the Select Folder button. Click OK to get out of the download options screen and then click Close to get out of the View Downloads screen.

NOTE: IE8 Does not support changing download locations in this manner. You will need to download the tool(s) to the default folder, usually Downloads, then copy them to the desktop.

Change default download folder location in Edge -Boot to a user account with admin status, select start > file explorer > right click on "Downloads" folder and select "Properties"

In the new window select "Location" tab > clear the text field box and type in or copy/paste %userprofile%\Desktop > select "Apply" then "OK"

Be aware you are not changing the Browser download folder location, you are changing the user’s download directory location.....

Next,

Follow the instructions in the following link to show hidden files:

http://www.howtogeek.com/howto/windows-vista/show-hidden-files-and-folders-in-windows-vista/

Next,

Open Malwarebytes, select > Reports > then checkmark (tick) most recent "Website Block" entry > then select "View Report" > "Export" > Text File (*.txt) name and save that file to Desktop or somewhere of your choice, attach to your reply...

Repeat for last three blocks, copy to your reply...

Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.
  • The tool will also make a log named (Addition.txt) Please attach that log to your reply.


Let me see those logs in your reply....

Thank you,

Kevin...

Thanks for those logs, continue with the following:

Open WinPatrol, remove the checkmark from "Automatically start WinPatrol when computer starts" reboot your PC to take effect...

Next,

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"
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,

Please open Malwarebytes Anti-Malware.
 
  • On the Settings tab > Protection Scroll to and make sure the following are selected:
    Scan for Rootkits

    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:

  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it

Next,

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

Retrieve the MSRT log as follows, and post it in your next reply:

You mention that the blocks have ceased, if there are no more issues or conceerns we can clean up:

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…

This has suddenly started happening to me, it is when I attempt to connect to my VPN (using Private Internet Access) it made everything behave strangely, to get around this I have had to disable Web Protection. I think this is a glitch with there updates? as I have been using this for years without any problems and now its suddenly became one.

I'm having precisely the same problem.  It just started earlier today.  How do we all find out what this means and how to fix it?

thanks!
