Svchost.exe


Go to solution Solved by AdvancedSetup,

Hello.

I found lot of svchost.exe processes in Process Explorer. All of these processes are veryfied from Microsoft, with no VirusTotal detections and they are children of "Service.exe".

I have read every legitimate svchost process should have "0" in session, but I found some svchost with "2".  I think path of these processes is normal (C:\Windows\System32\svchost.exe). I scanned that file with VirusTotal and Malwarebytes, but nothing was detected. I also did full scan with Windows Defender, Malwarebytes and did some scans with adwcleaner. These processes doesn't use lot of CPU.

Is this normal or should I be worried about that? I did clean Windows install and I think everything should be fine, but now I am not sure.

Edit: There are only 4 svchost.exe processes with session higher than "0". I didn't installed any pirated games or random software from internet, after reinstall I only installed few games from steam, google chrome, malwarebytes and programs from microsoft like process explorer.

There are a lot of them on all computers @PtrykPL that alone does not mean there is any infection on the system. Go ahead and run the steps below though and we'll see what we can find.

 

 

Please run the following steps and post back the logs as an attachment when ready.
Temporarily disable your antivirus or other security software first. Make sure to turn it back on once the scans are completed.
Temporarily disable Microsoft SmartScreen to download software below if needed. Make sure to turn it back on once the scans are completed.
If you still have trouble downloading the software please click on Reveal Hidden Contents below for examples of how to allow the download.

When downloading with some browsers you may see a different style of screens that may block FRST from downloading. The program is safe and used hundreds of times a week by many users.

Example of Microsoft Edge blocking the download

STEP 01

  • If you already have Malwarebytes installed then open Malwarebytes and click on the Scan button. It will automatically check for updates and run a Threat Scan.
  • If you don't have Malwarebytes installed yet please download it from here and install it.
  • Once installed then open Malwarebytes and select Scan and let it run.
  • Once the scan is completed make sure you have it quarantine any detections it finds.
  • If no detections were found click on the Save results drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If there were detections then once the quarantine has completed click on the View report button, Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If the computer restarted to quarantine you can access the logs from the Detection History, then the History tab. Highlight the most recent scan and double-click to open it. Then click the Export drop-down, then the Export to TXT  button, and save the file as a Text file to your desktop or other location you can find and attach that log on your next reply.
  • If Malwarebytes won't run then please skip to the next step and let me know in your next reply that the scanner would not run.

STEP 02

Please download AdwCleaner by Malwarebytes and save the file to your Desktop.

  • Double-click to run the program
  • Accept the End User License Agreement.
  • Wait until the database is updated.
  • Click Scan Now.
  • When finished, if items are found please click Quarantine.
  • Your PC should reboot now if any items were found.
  • After reboot, a log file will be opened. Attach or Copy its content into your next reply.

RESTART THE COMPUTER Before running Step 3

STEP 03
Please download the Farbar Recovery Scan Tool and save it to your desktop.

Note: You need to run the version compatible with your system. You can check here if you're not sure if your computer is 32-bit or 64-bit

  • Double-click to run it. When the tool opens, click Yes to disclaimer.
  • Press the Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it also makes another log (Addition.txt). If you've, run the tool before you need to place a check mark here each time
  • Please attach the Additions.txt log to your reply as well.
  • On your next reply, you should be attaching frst.txt and additions.txt to your post, every time.

 

Thanks

And something changed. Now there are not svchost.exe with session "2" but now it have "1" (I noticed this after I disabled "quick start" option). Path of these processes is still normal (system32). Every svchost process have same path. I scanned svchost.exe file with VirusTotal and there wasn't any detections and file had veryfied Microsoft signature. Yesterday I installed Kaspesky and run few scans. Also I scanned "svchost.exe" with this. Nothing was detected.

These processes still doesn't use many CPU and I think PC works fine.

I forgot to say one thing.

I found something about forced system restart in logs (or something like that). This is because I accidentally killed lsass process in process explorer.

Also I found few errors with Windows Defender scans or sometching like this (i think in addition.txt). I don't know what happened, but I did more scans. I also did one full scan with Windows Defender, before asking for help here. These scans didn't found anything.

Kaspersky is a very good antivirus. It did not find anything. Malwarebytes and AdwCleaner did not find anything either.
