Please download Malwarebytes Anti-Malware (v1.46) and save it to your desktop.Download Link 1
Download Link 2
MBAM may "make changes to your registry" as part of its disinfection routine. If using other security programs that detect registry changes (ie Spybot's Teatimer), they may interfere or alert you. Temporarily disable such programs or permit them to allow the changes.
  • Make sure you are connected to the Internet.
  • Double-click on mbam-setup.exe to install the application.
    For instructions with screenshots, please refer to the How to use Malwarebytes' Anti-Malware Guide.
  • When the installation begins, follow the prompts and do not make any changes to default settings.
  • When installation has finished, make sure you leave both of these checked:
    • Update Malwarebytes' Anti-Malware
    • Launch Malwarebytes' Anti-Malware
  • Then click Finish.
MBAM will automatically start and you will be asked to update the program before performing a scan.
  • If an update is found, the program will automatically update itself. Press the OK button to close that box and continue.
  • If you encounter any problems while downloading the definition updates, manually download them from here and just double-click on mbam-rules.exe to install.
On the Scanner tab:
  • Make sure the "Perform Quick Scan" option is selected.
  • Then click on the Scan button.
  • If asked to select the drives to scan, leave all the drives selected and click on the Start Scan button.
  • The scan will begin and "Scan in progress" will show at the top. It may take some time to complete so please be patient.
  • When the scan is finished, a message box will say "The scan completed successfully. Click 'Show Results' to display all objects found".
  • Click OK to close the message box and continue with the removal process.
Back at the main Scanner screen:
  • Click on the Show Results button to see a list of any malware that was found.
  • Make sure that everything is checked, and click Remove Selected.
  • When removal is completed, a log report will open in Notepad.
  • The log is automatically saved and can be viewed by clicking the Logs tab in MBAM.
  • Copy and paste the contents of that report in your next reply. Be sure to post the complete log to include the top portion which shows MBAM's database version and your operating system.
  • Exit MBAM when done.
Note: If MBAM encounters a file that is difficult to remove, you will be asked to reboot your computer so MBAM can proceed with the disinfection process. If asked to restart the computer, please do so immediately. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware.

Now rescan again with Malwarebytes Anti-Malware, but this time perform a Full Scan in normal mode and check all items found for removal. Don't forgot to check for database definition updates through the program's interface (preferable method) before scanning and to reboot afterwards. Failure to reboot normally (not into safe mode) will prevent MBAM from removing all the malware. When done, click the Logs tab and copy/paste the contents of the new report in your next reply.

The database in your previous log shows 4427. Last I checked it was 4436.

It's definitely running smoother.
Before, the malware would kick in and overwork the system,
which would also cause the cooling fans to begin revving up.

The system would also mysteriously turn on by it self after i turned it off.
All of these symptoms no longer exist.

If there are no more problems or signs of infection, you should Create a New Restore Point to prevent possible reinfection from an old one. Some of the malware you picked up could have been backed up, renamed and saved in System Restore. Since this is a protected directory your tools cannot access to delete these files, they sometimes can reinfect your system if you accidentally use an old restore point. Setting a new restore point AFTER cleaning your system will help prevent this and enable your computer to "roll-back" to a clean working state.

The easiest and safest way to do this is:
  • Go to Posted Image > Programs > Accessories > System Tools and click "System Restore".
  • Choose the radio button marked "Create a Restore Point" on the first screen then click "Next". Give the R.P. a name, then click "Create". The new point will be stamped with the current date and time. Keep a log of this so you can find it easily should you need to use System Restore.
  • Then use Disk Cleanup to remove all but the most recently created Restore Point.
  • Go to Posted Image > Run... and type: Cleanmgr
  • Click "Ok". Disk Cleanup will scan your files for several minutes, then open.
  • Click the "More Options" tab, then click the "Clean up" button under System Restore.
  • Click Ok. You will be prompted with "Are you sure you want to delete all but the most recent restore point?"
  • Click Yes, then click Ok.
  • Click Yes again when prompted with "Are you sure you want to perform these actions?"
  • Disk Cleanup will remove the files and close automatically.

Yes, i'll follow your advice and create a new restore point.

I wonder if these malware infections are coming over in STEAM updates.

Thanks Again.

You're welcome.

I wonder if these malware infections are coming over in STEAM updates.

See the link below and especially "How Malware Spreads - How did I get infected".

:thumbsup: Tips to protect yourself against malware and reduce the potential for re-infection:

Keep Windows and Internet Explorer current with all critical updates from Microsoft which will patch many of the security holes through which attackers can gain access to your computer. If you're not sure how to do this, see Microsoft Update helps keep your computer current.

Avoid gaming sites, porn sites, pirated software, cracking tools, keygens, and peer-to-peer (P2P) file sharing programs (i.e. Limewire, eMule, uTorrent). They are a security risk which can make your computer susceptible to a smörgåsbord of malware infections, remote attacks, exposure of personal information, and identity theft. Malicious worms, backdoor Trojans IRCBots, and rootkits spread across P2P file sharing networks, gaming, porn and underground sites. Users visiting such pages may see innocuous-looking banner ads containing code which can trigger pop-up ads and malicious Flash ads that install viruses, Trojans, and spyware. Ads are a target for hackers because they offer a stealthy way to distribute malware to a wide range of Internet users. Porn sites can lead to the Trojan.Mebroot MBR rootkit and other dangerous malware. The best way to reduce the risk of infection is to avoid these types of web sites and not use any P2P applications.Beware of Rogue Security software as they are one of the most common sources of malware infection. They infect machines by using social engineering and scams to trick a user into spending money to buy a an application which claims to remove malware. For more specific information on how these types of rogue programs and infections install themselves, read How Malware Spreads - How did I get infected

Keeping Autorun enabled on USB (pen, thumb, jump) and other removable drives has become a significant security risk as they are one of the most common infection vectors for malware which can transfer the infection to your computer. To learn more about this risk, please read:Many security experts recommend you disable Autorun asap as a method of prevention. Microsoft recommends doing the same.

...Disabling Autorun functionality can help protect customers from attack vectors that involve the execution of arbitrary code by Autorun when inserting a CD-ROM device, USB device, network shares, or other media containing a file system with an Autorun.inf file...
