Hello,
    
 
They call me TwinHeadedEagle around here, and I'll try to help your with your issue.
 
     
    
Before we start please read and note the following:

  • We're primarily oriented on malware removal here, so you must know that some issues just cannot be solved and you must be prepared for this. Some tools we use here will remove your browser search history, so backup your important links and all the files whose loss is unacceptable.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything not covered in my instructions happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Wow ... great job !!!

 

I rescanned with both Windows Security Essentials and Malwarebytes and there were no issues.

 

Then the real test was to shut the computer off and then restart  it to ensure the Trojan virus was not in quarantine by Windows Security Essentials. And, it is GONE !!!!!!

 

Thank you so much for your personal involvement and assistance.!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Since there are no more problems, we can declare this PC clean thumbs_up_smiley.gif

Now, we can proceed with post-cleanup procedures. Let's remove my tools and create a new, non infected restore point concurrently deleting old ones.

Step 1. - Creation of system restore point and tools removal.

Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run and wait until the tool completes his work.
  • All tools we used should be gone. Tool will create an report for you (C:\DelFix.txt). I don't need it for review.
Tool deletes old system restore points and creates a fresh system restore point after cleaning.

Step 2. - Tips and tricks to keep your computer clean, safe and in a good shape.

Security tips - highly recommended reading:

Maintenance tips:Additional software that I personally use and install on all my clients devices:
  • Malwarebytes' Anti-Malware (paid version highly recommended) - to scan your system from time to time in search for malware.
  • Malwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
  • McShield - to prevent infections spread by removable media.
  • Unchecky - to prevent from installing additional foistware, implemented in legitimate installations.
  • Adblock - to surf the web without annoying ads!
  • Qualys BrowserCheck - cloud service that scans your browsers and plugins to see if they’re all up-to-date.

My help is free for everybody.
