Solved DNS Unlocker - also infected...

[salzrat]

Very strange DNS Unlocker infection starting 2 hours ago. I notice it's dns unlocker because the popups mention something like "brought to you via DNS Unlocker", and the control panel allowed me to uninstall dns unlocker. The only thing I installed earlier today was an update to an electroic signature creation software.
I only attached a FRST log since that is what is mentioned in the assistance thread.
I did try to follow online guides about removing dns unlocker, but they propose removing plugins from the browsers. However, no plugins concerning dns unlocker are visible.

Thanks a lot in advance!

Hello,

Is this enterprise/business PC?

 

[salzrat]

No!

This certainly isn't home machine.

Hi,
I'm using this pc for research at university as well as privately, that's why you might see a lot of campus software installed.

But it's definitely not company or enterprise, as university is non-profit. In that sense, I believed it was ok to post here. Please let me know whether that fits with your policy, and sorry if I have misinterpreted anything - I'm amazed at the work you are doing here!

Thanks in advance!

Okay, this is fine.

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.
