DNS Error, MWAC Filter and MWB Website Protection


Brumm
 Share

Recommended Posts

Hello, 

A few days ago, I stopped being able to access both my hardline and wireless internet. I kept getting a DNS error when I tired to open any webpage.

As a work around, I found that if I hooked my wireless modem into a wireless router, and then used the wireless router connection, I was able to access the internet, but at very limited speeds. I worked with my internet service provider to get a new modem (which is now set up and working), and also ran some diagnostics on my computer - Windows troubleshooting and a Malwarebytes scan. (The Malwarebytes scan did not find anything.) 

The Windows troubleshooting pointed me to the "MWAC filter", and after reading online, I found that I was able to get full connectivity once I disabled the "Malwarebytes Website Protection" in the "Detection and Protection" settings. Reviewing some of the posts in this forum and comparing to the situation I am in, it may be that my computer is infected, which is the reason for this post. Having to disable "Malicious Website Protection" in order to access the internet is not ideal, obviously.

I've downloaded Farbar recovery scan tool (x64) and attached the FRST and ADDITION files as recommended in the "I'm infected - What do I do Now?" post.

Any help would be greatly appreciated.

Thanks,

Hello @Brumm and :welcome:

The logs show quite a few errors in the Event Logs. May be from a current or previous infection. Let's go ahead and scan for any current threats and go from there.

 

 

STEP 1
Please run a Threat Scan with MBAM. If you're unable to run or complete the scan as shown below, please see the following:
MBAM Clean Removal Process 2x
When reinstalling the program, please try the latest version.

Right click and choose "Run as administrator" to open Malwarebytes Anti-Malware and from the Dashboard please Check for Updates by clicking the Update Now... link
Open up Malwarebytes > Settings > Detection and Protection > Enable Scan for rootkit and Under Non Malware Protection set both PUP and PUM to Treat detections as malware.
Click on the SCAN button and run a Threat Scan with Malwarebytes Anti-Malware by clicking the Scan Now>> button.
Once completed please click on the History > Application Logs and find your scan log and open it and then click on the "copy to clipboard" button and post back the results on your next reply.


STEP 2
Please download Junkware Removal Tool to your desktop.

  • Shutdown your antivirus to avoid any conflicts.
  • Right click over JRT.exe and select Run as administrator on Windows Vista or Windows 7, double-click on XP.
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete.
  • On completion, a log (JRT.txt) is saved to your desktop and will automatically open.
  • Post the contents of JRT.txt into your next reply message
  • When completed make sure to re-enable your antivirus

STEP 3

adwcleaner_new.png Fix with AdwCleaner

Please download AdwCleaner by Xplode and save the file to your Desktop.

  • Right-click on adwcleaner_new.png icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • Accept the Terms of use.
  • Wait until the database is updated.
  • Click Scan.
  • When finished, please click Clean.
  • Your PC should reboot now.
  • After reboot, logfile will be opened. Copy its content into your next reply.

Note: Reports will be saved in your system partition, usually at C:\Adwcleaner

STEP 4
Download Sophos Free Virus Removal Tool and save it to your desktop.
 

  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View Log file (bottom left-hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found, please confirm that result.

STEP 5
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here.
  • Please attach the Additions.txt log to your reply as well.

 

Thanks

Hi Ron, 

Thanks for the feedback and sorry for the delay in my response. 

I was working through the steps you outlined and when I loaded the AdwCleaner version 6.0.4.0 (that was available from BleepingComputer, the link that was posted), I got the message: "You are currently running an outdated version of AdwCleaner. Please click [OK] in order to open AdwCleaner's download page in which you can get the latest version." 

Clicking [OK] brings me to this link: https://toolslib.net/downloads/viewdownload/1-adwcleaner/

Like a dummy, I downloaded it, but after thinking and getting a feeling that something might not be right, I went to delete it and accidentally opened it. (I went through the MalwareBytes website and could only find version 6.0.4.0, not 6.041 as was at this site, further adding to my unease.)

Nothing happened, but if it were a virus/malware, I wouldn't really expect it to. I should also note that I had the 6.0.4.0 version open at the time, but did not receive any messages. As quick as I was able, I deleted the 6.041 version exe file, disconnected from my internet, and reran all of the software that was listed. 

I will provide the txt files and confirmations that you requested shortly, but I just wanted to post this before rebooting my computer.  

Cheers, 

- Brumm

Hi Ron, 

The files that you requested are attached.

The JRT and MBW Hist with a " -2 " behind them are from re-runs of MWB and Junkware removal tool after the Adware situation that I described above. I also ran MWB an extra time (just for kicks) and provided file below with " -3".  

I'm not sure what happened to the [C1], or [S2] AdwCleaner files, since the [S1] and [C2] files were the only files present in the directory after the run.

The Sophos scan came up clean.

I did a complete power down, booted up and then ran the FarBar scan. The FRST and Addition files are attached. 

Cheers,

- Brumm

I notice you have the Killer Network on this system. They've had a few issues with previous older drivers. If you've not updated them please look at installing the latest drivers for your system.

http://www.killernetworking.com/driver-downloads

 

Please download the attached fixlist.txt file and save it to the Desktop.
NOTE. It's important that both files, FRST or FRST64 and fixlist.txt are in the same location or the fix will not work.

NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system.

Run FRST or FRST64 and press the Fix button just once and wait.
If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart.
The tool will make a log on the Desktop (Fixlog.txt). Please attach or post it to your next reply.

Note: If the tool warned you about an outdated version please download and run the updated version.

fixlist.txt

Thanks
