Hello,

This seems to be work/business machine? We do not provide help for work/business computers. This forum isrun by volunteers that spend their time free of charge. If you're making money via this PC then you should pay for its repair.

TwinHeadedEagle,
It's a personal use machine. It belongs to my sister. All she does is read email a little facebook and play casino games and solitaire on it, nothing business related. It was purchased from Costco a few months back and it was the only windows 7 machine they were selling at the time. I myself was surprised that it was win7 professional.
Please reconsider and help me to rid the plague from her machine. She got this virus the first week she had the machine and I did not even know she purchased a new computer until she was already infected. I therefore never got to do a system backup on clean untouched system. I would be very appreciative of any help you could give me and will be glad to donate something for your time.

v/r
Lou

Okay, let's start:


Download

Malwarebytes Anti-Rootkit to your desktop.

• Double-click the icon to start the tool.
• It will ask you where to extract it, then it will start.
• Warning! Malwarebytes Anti-Rootkit needs to be run from an account with administrator rights.
• Click in the introduction screen "next" to continue.
• Click in the following screen "Update" to obtain the latest malware definitions.
• Once the update is complete select "Next" and click "Scan".
• When the scan is finished and no malware has been found select "Exit".
• If malware was detected, make sure to check all the items and click "Cleanup". Reboot your computer.
• Open the MBAR folder and paste the content of the following files in your next reply:
  • "mbar-log-{date} (xx-xx-xx).txt"
  • "system-log.txt"

Scan with Farbar Recovery Scan Tool

Please re-run Farbar Recovery Scan Tool to give me a fresh look at your system.

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
• Make sure that Addition option is checked.
• Press Scan button and wait.
• The tool will produce two logfiles on your desktop: FRST.txt and Addition.txt.

Please include their content into your next reply.

TwinHeadedEagle,
I ran malwarebytes and it found one issue, I followed instructions to cleanup and the computer rebooted. After reboot I ran Farbar. Attached are the four output files

TwinHeadedEagle,
FYI:
While running the Malwarebytes I also noticed in taskmanager that almost equal # of dllhost*32 processes and IE applications running. I thought this was very odd since I had not started any IE sessions prior to or during the scan. Since the reboot from Malwarebytes cleanup I have yet to reconnect my lan drop or start up an IE. Right now there are no dllhost*32 processes stuck in the system. I logged into both created user accounts on the pc and used control panel to review their IE settings and noticed something odd. The profile under security/internet zone tab was set to custom in both user accounts. No one manually changed those settings. I should have seen that set to IE system default level. I will leave the pc offline and change nothing until I receive any further instruction from you.

Fix with Farbar Recovery Scan Tool

This fix was created for this user for use on that particular machine.

Running it on another one may cause damage and render the system unstable.

​

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

Both files, FRST and fixlist.txt have to be in the same location or the fix will not work!

• Right-click on
  
  icon and select
  
  Run as Administrator to start the tool.
  (XP users click run after receipt of Windows Security Warning - Open File).
• 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, called Fixlog.txt.

Please attach it to your reply.

TwinHeadedEagle,
Ran Farbar fix, logfile uploaded. The pc did reboot at end of cleanup process.
I checked both users IE settings afterwards and security/internet "security level" is still set to custom. PC still offline, will wait for your next instruction.

thanks
Lou

You can re-enable your Internet. Tell me how is your PC behaving now?

 

[LouSly]

TwinHeadedEagle,
I reinstalled my lan connection and have been using the PC for past hour without any reoccurrence of the dllhost*32 issue. I am hopeful that your help has rid me of this nasty infection.
Thank you very much for your time helping us.
Lou
