Alright, I've ran into a fun one for everyone to try and help solve because I am about to take it behind the wood shed...

Backstory: Got the computer, simply lagging hard etc. Personal Business computer so it's not exposed to the average internet etc. I'm just a friend that's good with computers haha.

Found that one of the svchost.exe processes was eating up literally 4-5 megs of RAM per second on boot till it hit over half a gig of RAM total. Figured simple infection

Ran scans:
Trend Micro
System Analyzer
Spyware Doctor

A few infected were found, false positives.

Went into more detail into what was running underneath the svchost.exe.

Tree of processes:
svchost.exe 492,348k
-->taskeng.exe 2,060k
-->taskeng.exe 8,876k
-->wuauclt.exe 2,912k

2k+8K+3K does not = 492k by any means????

I've gone through and removed any bloat startup programs. Stopped superfetch. Turned off any programs that would be running in the background that I could see in any way shape or form using memory. Still same boat.

I'm simply out of ideas...

Any help for a desperate and tired person?

It looks like an infection to me (Host Process using all those CPU cycles).
Possibly some rootkit.

Download Security Check from HERE, and save it to your Desktop.

* Double-click SecurityCheck.exe
* Follow the onscreen instructions inside of the black box.
* A Notepad document should open automatically called checkup.txt; please post the contents of that document.


Please download MiniToolBox and run it.

Checkmark following boxes:
  • Report IE Proxy Settings
  • Report FF Proxy Settings
  • List content of Hosts
  • List IP configuration
  • List Winsock Entries
  • List last 10 Event Viewer log
  • List Installed Programs
  • List Users, Partitions and Memory size
Click Go and post the result.


Download Malwarebytes' Anti-Malware (aka MBAM): https://www.bleepingcomputer.com/download/malwarebytes-anti-malware/ to your desktop.

* Double-click mbam-setup.exe and follow the prompts to install the program.
* At the end, be sure a checkmark is placed next to Update Malwarebytes' Anti-Malware and Launch Malwarebytes' Anti-Malware, then click Finish.
* If an update is found, it will download and install the latest version.
* Once the program has loaded, select Perform quick scan, then click Scan.
* When the scan is complete, click OK, then Show Results to view the results.
* Be sure that everything is checked, and click Remove Selected.
* When completed, a log will open in Notepad.
* Post the log back here.

Be sure to restart the computer.

The log can also be found here:
C:\Documents and Settings\Username\Application Data\Malwarebytes\Malwarebytes' Anti-Malware\Logs\log-date.txt
Or at C:\Program Files\Malwarebytes' Anti-Malware\Logs\log-date.txt


Please download GMER from one of the following locations and save it to your desktop:
  • Main Mirror
    This version will download a randomly named file (Recommended)
  • Zipped Mirror
    This version will download a zip file you will need to extract first. If you use this mirror, please extract the zip file to your desktop.
  • Disconnect from the Internet and close all running programs.
  • Temporarily disable any real-time active protection so your security programs will not conflict with gmer's driver.
  • Double-click on the randomly named GMER file (i.e. n7gmo46c.exe) and allow the gmer.sys driver to load if asked.
  • Note: If you downloaded the zipped version, extract the file to its own folder such as C:\gmer and then double-click on gmer.exe.

  • GMER will open to the Rootkit/Malware tab and perform an automatic quick scan when first run. (do not use the computer while the scan is in progress)
  • If you receive a WARNING!!! about rootkit activity and are asked to fully scan your system...click NO.
  • Now click the Scan button. If you see a rootkit warning window, click OK.
  • When the scan is finished, click the Save... button to save the scan results to your Desktop. Save the file as gmer.log.
  • Click the Copy button and paste the results into your next reply.
  • Exit GMER and be sure to re-enable your anti-virus, Firewall and any other security programs you had disabled.

IMPORTANT! If for some reason GMER refuses to run, try again.
If it still fails, try to UN-check "Devices" in right pane.
If still no joy, try to run it from Safe Mode.

I'd use a free firewall, MSE and super antispyware.
