Trojan Help (Artemis!)

[ConvexPolygon]

                  Hi, my Laptop has come down with some sort of infection, and I was hoping that this forum could be of some help. Last night I contracted a trojan. A user on Steam sent me a message saying they wanted to trade this item with me and gave a link. I clicked the link and something started downloading. I was immediately suspicious and closed the tab. However, a few seconds later a mcafee window popped up and said a Trojan had been automatically quarantined. I went to the "Quarantined files" window and deleted it. The name was Artemis!. It is no longer on mcafee and when I did a full scan it said I was secure. After that, I went to play some games on Steam. These games had a noticeably lower frame rate than before I downloaded the trojan. They are not unplayable, but are 20 fps lower than what I am used to. This is really frustrating and I kept trying to fix it. Next I did a full factory reset overnight, hoping to get rid of my game performance issues that way. Today, when I reinstalled the games my game performance was just as bad. What can I do to fix this? I would really appreciate if someone took time to help me.

 

My specs- Dell Inspiron 5537

Intel duel core i5 1.6ghz(2.3ghz)

Windows 8

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

• Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
• Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
• 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.
• Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
• Note that we may live in totally different time zones, what may cause some delays between answers.
• Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
• If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

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

Only one of them will run on your system, that will be the right version.

• Double-click to run it. When the tool opens click Yes to disclaimer.
• Press Scan button.

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.

fixlist.txt

Thanks again for your help.

Attached is the fixlog you asked for.

I just have one question. After the scan a message popped up saying the fix was over. After that my computer restarted, and upon turning on all of the accounts I had set to "remember me" were logged out. 

Also, I was curious as to if this was supposed to fix my framerate drops as it was titled "fix".

My game performance is still lesser than what it used to be.

Thanks!

Hi, thanks again.

When I ran the TDSSkiller nothing was found. This might have to do with the fact that I factory reseted, because everything I had on my system when I was infected got deleted. Attached are the files you asked for.

However when I try to attach the TDSSkiller to my reply, this comes up.

:

• TDSSKiller.3.0.0.42_04.01.2015_11.44.50_log.txt

  Upload Skipped (No file was selected for upload)

Addition.txt

FRST.txt

[TwinHeadedEagle]

Reports show no signs of malware. How is your PC behaving now?

[ConvexPolygon]

Way under what it was before I contracted the Trojan.

I did delete it with mcafee, so it may be gone, but I am still feeling the latency with demanding programs.

[TwinHeadedEagle]

I don't know how to help you further. Maybe you should clean the dust from your notebook.

[ConvexPolygon]

Thanks anyway!

[TwinHeadedEagle]

The Importance of Software Updating:

 

 
In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.
 
Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

• How to update Java
• How to update Adobe Reader

Recommended additional software:

 
 
TFC - to clean unneeded temporary files.
Malwarebytes' Anti-Malware - 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! 
 
 

Post-cleanup procedures:

 

 
Download DelFix by Xplode and save it to your desktop.

• Run the tool by right click on the icon and Run as administrator option.
• Make sure that these ones are checked:
  • Remove disinfection tools
  • Purge system restore
  • Reset system settings
• Push Run.
• The program will run for a few seconds and display a notepad report. You do not need to attach it.

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.
