Hi!

 

I posted this topic in the networking forum and after a few days of help it was decided that my internet connection is completely fine.  However, there might be a virus or malware preventing me from opening up a website.

 

I'll give a brief overview of what happened but all the other details can be found in this link:http://www.bleepingcomputer.com/forums/t/494478/wireless-network-says-im-connected-to-internet-but-no-real-internet-acces/

 

My wireless connection says I have an excellent connection to my network with all bars filled.  However, I cannot open any website using any browser nor can I use any chat client.  Basically anything that involves the internet is not working.  The good people at the networking forum finally decided that the internet connection is fine, as I have stated above.

 

So here is what I have done recently:

I downloaded mbam and renamed the setup.exe to anything and I also downloaded rkill and renamed it as well. I then set it up on the afflicted laptop.  I followed instructions on as to how to update mbam without internet access.  I have an updated mbam on another computer and copied its rules.ref and database.conf and replaced the ones on the laptop with the ones I copied so to update them.

 

Then I restarted the laptop and entered safe mode (w/o networking).  I ran rkill first and then I ran mbam and here are the logs:

Btw I am sorry if I am being verbose but I wanted you guys to know every step of what I did so I don't make a mistake.  And once again thanks for any help

 

Here all the logs:

I want you to run all tools listed below in normal mode.

 

p22002970.gif Download Security Check from here or here and save it to your Desktop.

  • Double-click SecurityCheck.exe
  • Follow the onscreen instructions inside of the black box.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

NOTE 1. If one of your security applications (e.g., third-party firewall) requests permission to allow DIG.EXE access the Internet, allow it to do so.
NOTE 2 SecurityCheck may produce some false warning(s), so leave the results reading to me.

p22002970.gif Please download Farbar Service Scanner (FSS) and run it on the computer with the issue.
  • Make sure the following options are checked:
    • Internet Services
    • Windows Firewall
    • System Restore
    • Security Center/Action Center
    • Windows Update
    • Windows Defender
    • Other Services
  • Press "Scan".
  • It will create a log (FSS.txt) in the same directory the tool is run.
  • Please copy and paste the log to your reply.


p22002970.gif Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Devices (do NOT change any settings here)
  • List Users, Partitions and Memory size

Click Go and post the result.

p22002970.gif Download Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

Be sure to restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt

p22002970.gifDownload Malwarebytes Anti-Rootkit from HERE to your Desktop.
  • Unzip downloaded file.
  • Open the folder where the contents were unzipped and run mbar.exe
  • Follow the instructions in the wizard to update and allow the program to scan your computer for threats.
  • DO NOT click on the Cleanup button. Simply exit the program.
  • When done, please post the two logs produced they will be in the MBAR folder..... mbar-log-xxxxx.txt and system-log.txt


p22002970.gif Please download Rkill (courtesy of BleepingComputer.com) to your desktop.
There are 2 different versions. If one of them won't run then download and try to run the other one.
You only need to get one of these to run, not all of them. You may get warnings from your antivirus about this tool, ignore them or shutdown your antivirus.

rKill.exe: http://www.bleepingcomputer.com/download/rkill/dl/10/
iExplore.exe (renamed rKill.exe): http://www.bleepingcomputer.com/download/rkill/dl/11/

  • Double-click on the Rkill desktop icon to run the tool.
  • If using Vista or Windows 7 right-click on it and choose Run As Administrator.
  • A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully.
  • If not, delete the file, then download and use the one provided in Link 2.
  • Do not reboot until instructed.
  • If the tool does not run from any of the links provided, please let me know.


If normal mode still doesn't work, run the tool from safe mode.

When the scan is done Notepad will open with rKill log.
Post it in your next reply.

NOTE. rKill.txt log will also be present on your desktop.
