Hi and thanks for the logs. Lets sort this out :D

First...
 

noentry32.png P2P WARNING!

It appears that there is at least one Peer to Peer(P2P) program on your computer:

UTorrent

Whilst some P2P programs themselves may be harmless, we at GeeksToGo do not recommend their use due to the extremely high likelyhood of obtaining an infection from files that have been downloaded. This may range from annoying adware to malicious trojans stealing your passwords and other personal information.

There is also the risk of inadvertently sharing information that wasn't intended due to incorrectly configured software.

It is highly likely that this is the source of the issue that brought you here today. And if not, probably what will bring you back at a later date.

Here are some useful links regarding the dangers of P2P software.

Then...

FRST Fix

If FRST.exe/FRST64.exe is not on your desktop, please download Farbar Recovery Scan Tool and save it to your desktop.

  • Download the attached Attached File  fixlist.txt   1.94KB   204 downloads and save it to your desktop <<< very important - it must be in the same location as FRST.exe/FRST64.exe
  • Right click frst.png and run as administrator. When the tool opens click Yes to the disclaimer.
  • Press the Fix button.
  • The system will restart.
  • It will produce a log called fixlog.txt on your Desktop.
  • Please copy and paste the contents of that log back here.

    NOTICE: This script was written specifically for this user, for use on that particular machine. Running this on another machine may cause damage to your operating system.

Items I need to see in your next post:

  • FRST Fixlog
  • How is it looking after the reboot?

You had a powelik infection which actually doesn't have any files as such which is why it was not detected.
It works via a registry modification.

We still need to check again to make sure it has all gone. And the previously mentioned ESET scan would be really helpful as it may pick up some remnants that we can't see using other methods.

Supplemental FRST Scan
Please run FRST64 again from your Desktop. If you do not currently have it on your system, download it from here and save it to your desktop.

  • Right click frst.png to run as administrator . When the tool opens click Yes to the disclaimer.
  • Press Scan button.
  • It will produce a log called FRST.txt in the same directory the tool is run from.
  • Please copy and paste log back here.

Your machine is looking pretty good now. Let's check for out of date security programs before finalising.
 
Security Check

Download Security Check by screen317 from here or here.
  • Save it to your Desktop.
  • Double click securitycheck.png SecurityCheck.exe and follow the onscreen instructions inside of the black box.
  • NOTE: If SecurityCheck aborts and you get the following message: UNSUPPORTED OPERATING SYSTEM! ABORTED! try rebooting the system and then run SecurityCheck again.
  • A Notepad document should open automatically called checkup.txt; please post the contents of that document.

Hi there. There are a couple of items that need dealing with as they are out of date. Instructions are below.
Once
 
JAVA Advice
WARNING: Java is the #1 exploited program at this time. The Department of Homeland Security recommends that computer users disable Java
See this article and this article.
I would recommend that you completely uninstall Java unless you need it to run an important software or need it to play games on-line.
In that instance I would recommend that you only use Firefox or Chrome to visit those sites and do the following:

  • For Firefox, install the NoScript add-on.
  • For Chrome, install the ScriptNo add-on.
    -->IMPORTANT<--: After installing the add-ons you will need to tell them that the site you are visiting is allowed to run Javascript. If you don't, the sites won't work properly. Or not at all. You can go to the NoScript home page here to learn how to use the add-on.
  • Disable Java in your browsers until you need it for that software and then enable it. (See How to disable Java in your web browser or How to unplug Java from the browser)

If you still want to update your Java, follow the instructions below:

A.
Your version of Java is out of date. Older versions have vulnerabilities that malicious sites can use to exploit and infect your system. Please follow these steps to remove older versions of Java components and update:

  • Download the latest version of the Java Runtime Environment (JRE) Version from Here and save it to your desktop.
  • Look for "Java Platform, Standard Edition". You will see the current Java version and update number under listed under the heading. Example: The newest update is Java SE 8u25
  • Click the "Download button under "JRE".
  • On the Java SE Runtime Environment page, click the button to "Accept License Agreement".
  • Under the Java SE Runtime Environment 8u25 heading:
    To install the version for your system:
    • For Windows 64bit systems, look for Windows x64 - 88.37MB, click the jre-8u25-windows-64.exe file and save it to your desktop. Do Not run it from the Java site.
  • Close any programs you may have running - especially your web browser.

B.
Uninstall all versions of Java

  • Click Start > Control Panel > Add/Remove Programs. The list of installed programs will populate.
  • Click the Start Orb, then Control Panel. Under the Programs or Programs and Features section click Uninstall a program. The list of installed programs will populate.
  • Remove all older versions of Java. These may call themselves: Java Runtime, Runtime Environment, Runtime, JRE, Java Virtual Machine, Virtual Machine, Java VM, JVM, VM, J2RE or J2SE
    The versions I see on the computer are:
    • Java 7 Update
    • Java 8 (64-bit)
    • Java SE Development Kit 8
  • Right click each program and click Uninstall and follow the on screen instructions for the Java uninstaller.
  • Repeat as many times as necessary to remove each Java version.
  • Reboot your computer once all Java components are removed.

C.
Install the latest JAVA

Back on your desktop:

  • Right click the  jre-8u25-windows-x64.exe file, click Run as Administrator and OK the UAC prompt to install the newest version.
  • When the Java Setup - Welcome window opens, click the Install > button.
  • If offered to install a Toolbar, just uncheck the box before continuing unless you want it.

[Note:] The Java Quick Starter (JQS.exe) adds a service to improve the initial start up time of Java applets and applications. To disable the JQS service if you don't want to use it, go to Start > Control Panel > You will have to be in Classic View to see Java(It looks like a coffee cup). Double-click on Java click the Advanced Tab click Miscellaneous and uncheck the box for Java Quick Starter. Click OK and reboot your computer.


Update Adobe Flash Player

NOTE: Depending on your settings, you may have to temporarily disable your antivirus software and firewall.

  • Please click here to go to the FlashPlayer Installation page.
  • In the first column, Adobe Flash Player, make sure the system version (64bit) and the browser are correct.
    • Note: If you use IE and other browsers you will need to install both Flash Player for IE and Flash Player for Other Browsers.
  • In the middle column, Optional offer:, UNCHECK the box next to Yes, install free McAfee Security Scan Plus
  • Click the Install now button. A download window for the install_flashplayer15x64_mssd_aaa_aih.exe file will open. Save it to the desktop.
  • Close the browser and all open windows.
  • Back on the desktop, right click the install_flashplayer15x64_mssd_aaa_aih.exe file and click Run as Administrator to install Flash Player.

If you could post when you have completed these, we can proceed.
 
Thank you.

Good news, it looks like your system is now clean. A good workman cleans up after himself so let's now attend to that :D

Tool Removal

We need to remove the tools we've used during cleaning your machine
  • Download Delfix from here
  • Ensure Remove disinfection tools is ticked
    Also tick:
    • Activate UAC
    • Create registry backup
    • Purge system restore
    • Reset System Settings
    delfix-select.png
  • Click Run
  • The program will run for a few moments and then notepad will open with a log. Please paste the log in your next reply

    We need to uninstall a program
    Open Programs and Features by clicking the Start button, clicking Control Panel, clicking Programs, and then clicking Programs and Features.
    Select the following programs from the list below, one at a time and click Uninstall.
    • ESET Online Scanner
    Delete the following Files and Folders (If Present):
    C:\Program Files(86)\ESET
    On the Desktop:
    install_flashplayer15x64_mssd_aaa_aih.exe
    jdk-8u25-windows-x64.exe



    Delete any other .bat, .log, .reg, .txt, and any other files created during this process, and left on the desktop and empty the Recycle Bin.

    ie.png Internet Explorer

    As you are running an outdated version of Internet Explorer, it is recommended that you update is as a priority to ensure you are receiving the most up date protection and features.

    To update, GO HERE to download Internet Explorer 11 directly.

    Alternatively, it will be updated via Windows Updates. If you are not using automatic updates, then it is recommended that you enable this feature to ensure you are up to date.

    Keep your machine updated

    Due to the ever-present tide of malware, it is important to ensure your computer is kept up-to-date to minimize the risk of future infection. An important step is to ensure that automatic updates are enabled.


    To enable automatic updates:

    Windows 7
    To turn on Automatic Updates yourself, follow these steps:
    • Click Start, type Windows update in the search box, and then click Windows Update in the Programs list.
    • In the left pane, click Change settings.
    • Select the option that you want.
    • Under Recommended updates, select the Give me recommended updates the same way I receive important updates or Include recommended updates when downloading, installing, or notifying me about updates check box, and then click OK.
    It is recommended to install an anti-malware to help prevent reinfection.
    Below are some free ones that can help keep you clean.

    Malwarebytes AntiMalware

    As you have installed Malwarebytes, I recommend that you keep this program and use it to help you stay clean.

    The free version will scan your computer and fix the problems it finds but will not provide real-time protection. You must scan regularly to find any threats.
    Consider purchasing the full version for active monitoring of threats.


    Update Other Programs

    Alongside keeping Windows updated, other programs installed on your computer should also be kept current as they too can introduce security risks.

    Filehippo Update Checker will scan your computer for out of date programs and provide download links for the updates. This is worth doing on a regular basis.

    Cryptolocker Warning
    Go here for information about CryptoLocker Ransomeware.
    The main thing with this infection is ~ Backup.
    If you're using an external hard drive, keep it unplugged from the computer when you're not backing up files or using it. This will prevent the infection from getting to your backed up files if you ever do come across it.

    Recommended Programs
    Unchecky is a small service that runs in the background to help keep those "extra toolbars" and tag along search engines from automatically installing. By automatically directing you to a custom install with all the options unchecked, only what you manually choose and confirm gets installed.
    CryptoPrevent is a free program that prevents CryptoLocker / ransomware from infecting your PC by locking down the OS so the malware can not get a grip on your system.
    Web Of Trust is a browser add-on designed to alert the user before interacting with a potentially malicious website. It will highlight green if a site is known to be safe.

    Adblock is a firefox browser add-on that blocks annoying banners, pop-ups and video ads.

    General Advice
    • When browsing the internet, look closely at the links you click on. Some aren't always what they seem
    • Avoid Peer to Peer file sharing utilities, these are a minefield of malware infections.
    • Don't open email attachments unless you are expecting them. Even an email from your best friend can be infected, they might not have sent it.
    • Pay attention when installing a program to your computer, particularly to any check boxes that may appear during installation, it is common for unwanted software to be installed in this way.
