For the past week I have noticed that 'svchost(secsvcs)' has been using 40-50% of my available CPU time. Sometimes I goes away after a few minutes but there are occasions where it has run for an hour or more. The only way I know to get rid of it is to restart the computer. What else can be done?

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.

    Posted Image
  • 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.

Hi Broni,


Last night I followed your instructions in an attempt to find out why SVCHOST was using so much CPU time. The first several test programs ran fine but the last one, GMER, which created an additional random program name failed with the following message: "fckm159.exe has stopped working...". My only option at that point was to close the program. I followed up by restarting the computer after which the computer crashed less than four minutes later with a BSOD. Upon the successive restart, once again the computer crashed with another BSOD. It did not crash in SAFE MODE. I disabled all of the startup programs contained in 'MSCONFIG' and restarted. Once again, the computer crashed. It would even crash when left alone without logging in. I attempted to follow up with a system restore but there was not enough time before it once more. At this point I had no other option but to restore the computer to an earlier image backup. Thank God I only lost one week's worth of work. Now what? :angry:

Can you operate normally from safe mode?

I have since restored my computer from an image backup from last week, however, while the system was crashing each time I started it, I did try safe mode. While in safe mode the system did not crash.

Since you restored from image are you having any issues?

Presently there are no problems but I expect that there will be times when SVCHOST will take over the computer just as before. This has been an intermittent problem over the past month and I do not expect it to subside without some sort of resolution. In most cases I have been able to wait it out for 5-10 minutes or more until the problem just goes away. There have been times, however, when SVCHOST completely takes over the computer and the only resolution is to restart.

Thanks for trying to help. I appreciate the time you have given to me. I guess I will just have to live with this unless someone comes up with a better or safer solution.

If you image was infection free and the issues will still come up it'd be more likely some hardware issue.
