dllhost.exe hogging cpu, malicious website blocked popups never-ending


Recommended Posts

Hubby was at NFL site this morning when avast announced that a threat was detected but I didn't have time to check it.  He left, I went to store and when I returned the fan was blowing hard and I shut down all the internet windows but the cpu was still at 100% with a lot of dllhost.exe things running.  When I brought ie back up I had to relogin to all my normal sites (twitter, tumblr, facebook) which I thought was odd.  I downloaded malware bytes free which quarantined some stuff but did not solve my problem. The "Malicious Website Blocked" popups from malwarebytes said the source was windows\syswow64\dllhost.exe so I went there and set it to run in the sandbox.  Since that time I still get the warnings but my CPU is not going crazy, the dllhost things are not using any of the CPU.  I bought the premium malwarebytes and it found nothing even though I am getting the popups.


I ran the farbar tool.  I am attaching the files. 


Thank you for any help,

Hello Cami and :welcome:! My name is Borislav and I will be glad to help you solve your malware problem.

Please note:

  • I recommend you to keep the instructions I will be giving you so that they are available to you at any time. You can save them in a text file or print them.
  • Make sure you read all of the instructions and fixes thoroughly before continuing with them.
  • Follow my instructions strictly and don’t hesitate to stop and ask me if you have any questions.
  • Post your log files, don't attach them. Every log file should be copy/pasted in your next reply.
  • Do not perform any kind of scanning and fixing without my instructions. If you want to proceed on your own, please let me know.
Step 1

Please uninstall the following applications:

Catalina Savings Printer

Coupon Printer for Windows

Pogo Games

Zip Opener Packages

Step 2

  • Launch Malwarebytes' Anti-Malware
  • Go to Update tab and select Check for Updates. If an update is found, it will download and install the latest version.
  • Go to Scanner tab and select Threat Scan, then click Scan.
  • The scan may take some time to finish,so please be patient.
  • When the scan is complete, click OK, then Show Results to view the results.
  • Make sure that everything is checked, and click Remove Selected.
  • When disinfection is completed, a log will open in Notepad and you may be prompted to Restart. (See Extra Note)
  • The log is automatically saved by MBAM and can be viewed by clicking the Logs tab in MBAM.
  • Copy&Paste the entire report in your next reply.
Extra Note: If MBAM encounters a file that is difficult to remove, you will be presented with 1 of 2 prompts, click OK to either and let MBAM proceed with the disinfection process, if asked to restart the computer,please do so immediately.

Step 3

Download attached fixlist.txt file and save it to the Desktop.

NOTE. It's important that both files, FRST/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 that particular machine. Running this on another machine may cause damage to your operating system

Run FRST/FRST64 and press the Fix button just once and wait.

If for some reason the tool needs a restart, please make sure you let the system restart normally. After that let the tool complete its run.

When finished FRST will generate a log on the Desktop (Fixlog.txt). Please post it to your reply.

In your next reply, post the following log files:

Thank you for your response.  I had two instances of the catalina savings printer and was able to uninstall one, but the other gets an error.  "The feature you are trying to use is on a network resource that is unavailable."


The threat scan did not reveal anything.  I am pasting it below.  I then ran the frst and now I have no dllhost.exe in my task manager window.  Yay.
