Hello Darknight474 and welcome to Malwarebytes,

Continue with the following:

If you do not have Malwarebytes installed do the following:

Download Malwarebytes version 3 from the following link:

https://www.malwarebytes.com/mwb-download/thankyou/

Double click on the installer and follow the prompts. If necessary select the Blue Help tab for video instructions....

When the install completes or Malwarebytes is already installed do the following:

Open Malwarebytes, select > "settings" > "protection tab"

Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on....

Go back to "DashBoard" select the Blue "Scan Now" tab......

When the scan completes quarantine any found entries...

To get the log from Malwarebytes do the following:
 
  • Click on the Report tab > from main interface.
  • Double click on the Scan log which shows the Date and time of the scan just performed.
  • Click Export > From export you have two options:
    Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply
    Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply

Next,

Download AdwCleaner by Malwarebytes onto your Desktop.

Or from this Mirror
 
  • Right-click on AdwCleaner.exe and select user posted imageRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users)
  • Accept the EULA (I accept), then click on Scan
  • Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Clean button. This will kill all the active processes
  • Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it
  • After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply


Next,

Download Farbar Recovery Scan Tool and save it to your desktop.

Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html

Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version.

If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way...

Be aware FRST must be run from an account with Administrator status...
 
  • Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.)
  • Make sure Addition.txt is checkmarked under "Optional scans"
    user posted image
     
  • Press Scan button to run the tool....
  • It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply.

Thank you,

Thanks for those logs Darknight474,

Continue with the following:

Download attached fixlist.txt file (end of reply) and save it to the Desktop, or the folder you saved FRST into. "Do not open that file when running FRST fix"
NOTE. It's important that both FRST and fixlist.txt are in the same location or the fix will not work.

Open FRST and press the Fix button just once and wait.
The tool will make a log on the Desktop (Fixlog.txt) or the folder it was ran from. Please post it to your reply.

Next,

Download Sophos Free Virus Removal Tool and save it to your desktop.

If your security alerts to this scan either accept the alert or turn off your security to allow Sophos to run and complete.....

Please Do Not use your PC whilst the scan is in progress.... This scan is very thorough so may take several hours...
 
  • Double click the icon and select Run
  • Click Next
  • Select I accept the terms in this license agreement, then click Next twice
  • Click Install
  • Click Finish to launch the program
  • Once the virus database has been updated click Start Scanning
  • If any threats are found click Details, then View log file... (bottom left hand corner)
  • Copy and paste the results in your reply
  • Close the Notepad document, close the Threat Details screen, then click Start cleanup
  • Click Exit to close the program
  • If no threats were found please confirm that result....



The Virus Removal Tool scans the following areas of your computer:
  • Memory, including system memory on 32-bit (x86) versions of Windows
  • The Windows registry
  • All local hard drives, fixed and removable
  • Mapped network drives are not scanned.



Note: If threats are found in the computer memory, the scan stops. This is because further scanning could enable the threat to spread. You will be asked to click Start Cleanup to remove the threats before continuing the scan.

Saved logs are found here: C:\ProgramData\Sophos\Sophos Virus Removal Tool\Logs

Let me see those logs in your reply, also tell me if you have any remaining issues or concerns..

Thank you,

Kevin...

This current issue does not seem to be related to Malware or Infection, possibly a none Microsoft Service...? Run your system in "Clean Boot" mode, see if that makes any differnce..

Set windows up for "Clean Boot" mode, full instructions here: https://support.microsoft.com/en-gb/kb/929135

Basically all none MS services are disabled, see how your system runs in that mode. Obviously 3rd party services that affect security or internet connection can be left active.

If clean boot makes your system faster and more responsive it is now a process of elimination to find which non MS service(s) was affecting your system...

Go through the process again, this time with all MS services hidden again enable the top half of non MS services, re-boot and see how your system responds, if still ok the top half can be left enabled.

Repeat again, enable so many of the bottom half then re-boot. Continue until you locate the problem service(s). A process of elimination, a bit long winded but worth the effort. Let me know the outcome...
 
Thank you,
 
Kevin

No need to apologise, real life can definitely consume alot of anyones time... There is no obvious Malware or Infection showing in your logs...? Try one more scan..

Go here and click 'SCAN NOW' under 'ESET Online Scanner' save to your Desktop.

Turn off the real-time scanner of any existing antivirus program before performing the online scan. Here's how

Right click on user posted image and select "Run as Administrator"

In the new Window accept the terms of service

user posted image

In the new Window select "Enable detection of potentially unwanted applictions" then expand "Advanced Settings"

user posted image

In the new Window checkmark (tick) the entries as shown, make sure "Clean threats automatically" is not checkmarked. Now select "Scan"

user posted image

In the new Window new virus database signatures will download, Do Not Select Stop

The Window will progress showing the scan in action....

In the new Window if no threats are found, select "Delete applications data on close" then select "Finish" no log is produced, confirm that in your reply...

If threats are found the following Window will open:

Click on "Select All" then "Save to Text file" name and save that file, attach to your reply.

Now select "Do not clean" and then close out....

Thanks for the TM screenshot, now I can see why you are having the spikes you describe.

"softwareschutzplattform-Dienst von Microsoft " translated to english is "Microsoft software protection platform service" 

Have a read here:

https://answers.microsoft.com/en-us/windows/forum/windows_10-performance-winpc/microsoft-software-protection-platform-service/3edad018-280e-49eb-b80e-af6146bb22b1

Specifically the last reply on page one and the remaining replies on page two. Let me know your thoughts on that service....
