www.msn.com and www.facebook.com blocked on one computer


Recommended Posts

One computer on my network at home cannot access two sites: www.msn.com and www.facebook.com. No other computer has any issues with accessing these sites. The Windows firewall is turned off and Norton 360 does not have these sites restricted. I even turned off Norton briefly to test for access without success. I have tried to restore the computer to a time prior to this issue occuring, but the computer encounters an error each time and cannot complete the restoration. I downloaded, updated, and scanned with malwarebytes free version, but it did not find any threats. I have updated and scanned with Norton 360 and it did not find any threats either. Since only one computer has this issue I suspect I have some kind of virus. Has anyone experienced a similar issue like this? Anyone have any suggestions to fix? Thanks for any help.

Hello swo_dog! Welcome to Malwarebytes' Anti-Malware Forums!

My name is Borislav and I will be glad to help you solve your problems with malware. Before we begin, please note the following:

  • The process of cleaning your system may take some time, so please be patient.
  • Follow my instructions step by step if there is a problem somewhere, stop and tell me.
  • Stay with the thread until I tell you that your system is clean. Missing symptoms does not mean that everything is okay.
  • Instructions that I give are for your system only!
  • If you don't know or can't understand something please ask.
  • Do not install or uninstall any software or hardware, while work on.
  • Keep me informed about any changes.

Download DDS and save it to your desktop from here or here or here.

Double click dds.scr to run the tool.

  • When done, DDS will open two (2) logs:
    1. DDS.txt

**Note: If you need more detailed information, please visit the web page of ComboFix in BleepingComputer. **

Please note that these fixes are not instantaneous. Most infections require more than one round to properly eradicate.

Stay with me until given the 'all clear' even if symptoms diminish. Lack of symptoms does not always mean the job is complete.

Kindly follow my instructions and please do no fixing on your own or running of scanners unless requested by me or another helper.

Please download ComboFix from

Here or Here to your Desktop.

**Note: In the event you already have Combofix, this is a new version that I need you to download. It is important that it is saved and renamed following this process directly to your desktop**

  1. If you are using Firefox, make sure that your download settings are as follows:
    • Open Tools -> Options -> Main tab
    • Set to Always ask me where to Save the files.

[*]During the download, rename Combofix to Combo-Fix as follows:

CF_download_FF.gif

CF_download_rename.gif

[*]It is important you rename Combofix during the download, but not after.

[*]Please do not rename Combofix to other names, but only to the one indicated.

AFsAKgBd-Close any open browsers.

[*]Close/disable all anti virus and anti malware programs so they do not interfere with the running of ComboFix.

-----------------------------------------------------------

  • Very Important! Temporarily disable your anti-virus, script blocking and any anti-malware real-time protection before performing a scan. They can interfere with ComboFix or remove some of its embedded files which may cause unpredictable results.
  • Click on this link to see a list of programs that should be disabled. The list is not all inclusive. If yours is not listed and you don't know how to disable it, please ask.

    -----------------------------------------------------------


  • Close any open browsers.
  • WARNING: Combofix will disconnect your machine from the Internet as soon as it starts
  • Please do not attempt to re-connect your machine back to the Internet until Combofix has completely finished.

[*]Double click on combo-Fix.exe & follow the prompts.

When I clicked on the file I got the following:

"Some installation files are corrupt. Please download a fresh copy of ComboFix.exe."

The only option was to click OK in that error window. Now a small window is up with "comboFix" and a green bar below that indicates it is running but I did not get the first window indicating it is preparing to run. Appears to be stuck and not processing.

I closed the window with the green bar, deleted the previous version of ComboFix and downloaded it again from the second link labeled as "here". This time it worked. Note that today when I started my computer and before downloading ComboFix I was able to access the previously unaccessible websites. I ran ComboFix and the report follows. Thanks again very much for the help.

When I turned on my computer today and before I downloaded and ran ComboFix I was able to access both the previously blocked websites. I was still able to access both afterwards as well. However, now I am back to the same symptoms where I cannot access either site from this computer. It's not just that I cannot log in, but rather the pages will not load, but other sites work fine. I get the "Internet Explorer cannot display the webpage" error. When I ping either site they cannot be found. Did you see anything unusual in the logs? It's all jiberish to me.
