Hello DWSmith and welcome to Malwarebytes,

Continue with the following:

If you do not have Malwarebytes installed do the following:

Download Malwarebytes version 3 from the following link:


Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > "settings" > "protection tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes deal with any found entries...

To get the log from Malwarebytes do the following:

  • Click on the Report 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: > From export you have two options:

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" 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,

I already performed all the following on my PC prior to your response,

I have also listed some issues I have encountered the past few days.

Did not complete successfully. Failed scanning drive C:\
Files and Settings not changed.

I see no presence of Malware or Infection in the FRST logs. The dns server address you mention "" is not malicious, there is no evidence of spamming or any untoward actions whatsoever. It is still on your system because you chose not to remove it with RogueKiller


[PUM.Dns] (X64) HKEY_LOCAL_MACHINE\System\ControlSet001\Services\Tcpip\Parameters\Interfaces\{21dacc90-e093-427f-8cbc-5447c581b6cf} | DhcpNameServer : ([United States])  -> Not selected

I have no idea why that address is on your system, my own action would be to remove it if I was not aware of any reasons for its presence.....

Regarding Windows Defender Controller Folder Actions,


Windows Defender notifications : Controlled folder keeps blocking changes to files. 

That is as per design... https://support.microsoft.com/en-us/help/4046851/windows-10-controlled-folder-access-windows-defender-security-center

If you are having trouble with System Restore (Normally turned off windows 10) or any other system actions then consider system refresh...


Run the following check and post the results for me to review;

Select the Windows key and X key together, from the winx menu select "Command Prompt (Admin)"

At the prompt type or copy/paste :- DISM /Online /Cleanup-Image /CheckHealth then hit the enter key. What results do you get..?

You`re very welcome Diane, and thank you for the kind donation. Continue...
Right click on FRST here: C:\Users\diane\FARBAR\FRST64.exe and rename to uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator"

If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST64 to uninstall

That action will remove FRST and all created files and folders...
