I allowed someone to plug an external hard drive into my MS Surface 1 running Windows 8.1.  Windows Defender immediately gave me a warning about malware.  A file was quarantined and removed, but I worry that an infection remains.  I've noticed that, at least on one website, images and formatting are not loading or are appearing differently, since the event.  

 

Windows Defender's history says this:

Detected Item - Trojan:Win32/Alureon!inf, Alert Level - Severe, Date - 8/26/2014 4:05pm

 

Subsequent scans fail to find anything.

 

I was unable to run DDS.  "DDS is not meant to run in compatibility mode."

 

I would love to know how to confirm my PC is clean, and remove the malware if it isn't.  Any help you can provide would be greatly appreciated.

  • Once MBAM opens, when it says Your databases are out of date, click the Fix Now button.
  • Click the Settings tab at the top, and then in the left column, select Detections and Protections, and if not already checked place a checkmark in the selection box for Scan for rootkits.
  • Click the Scan tab at the top of the program window, select Threat Scan and click the Scan Now button.
  • If you receive a message that updates are available, click the Update Now button (the update will be downloaded, installed, and the scan will start).
  • The scan may take some time to finish,so please be patient.
  • If potential threats are detected, ensure that Quarantine is selected as the Action for all the listed items, and click the Apply Actions button.
  • While still on the Scan tab, click the link for View detailed log, and in the window that opens click the Export button, select Text file (*.txt), and save the log to your Desktop.
  • The log is automatically saved by MBAM and can also be viewed by clicking the History tab and then selecting Application Logs.
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.

Thanks for this, nasdaq.  It's incredibly reassuring to discover there is a community like this offering this type of assistance.
 
The computer seems to be running well.  I've noticed no further suspicious behavior, so that I'm hoping I was simply paranoid.  The logs are posted below.  I omitted the log created by Malwarebytes, since you didn't explicitly state it should be posted.  If it's needed, just let me know and I'll post it.  
 
edit: logs removed, thanks for your help!

It appears that this issue is resolved, therefore I am closing the topic. If that is not the case and you need or wish to continue with this topic, please send me or any Moderator a Personal Message (PM) that you would like this topic re-opened.
