10 to 20 copies of dllhost.exe running in task manager


Recommended Posts

Hello,

 

I recently discovered I had 10 to 20 copies of dllhost.exe running in my task manager. I shut down my computer and restarted, and I had 10 to 20 copies of raptr_ep64.exe (a gaming program I don't use but which was bundled with a game I bought) running in the task manager.

 

Also, at one point I ran Paint Shop Pro and it informed me that an "OLE screen capture" is currently running. MSERT.exe also detected a Java/Obfuscator.W object.

 

Is my computer infected? McAfee scanner and Emsisoft scanner don't seem to detect anything. I've seen threads stating that multiple dllhost.exe tasks is the sign of a serious infection, which has me really worried. Attached are the requested log files. Any help would be greatly appreciated. Thank you very much.

Everything seems normal, but it's hard to know for sure. The symptom of 10-20 dllhost.exe or raptr tasks had stopped appearing after a few restarts even before I ran the fix, but I was worried that if a Trojan was causing them it'd still be lurking on my system. Is there a particular scanner I should use to confirm my system is clean of this particular infection?

The site itself doesn't seem to be Hijacked. Could have been a malicious advertisement, or there could still be malware lurking on your system.

These next 2 tools target Adware & Junkware in general.

Download AdwCleaner and save it on your desktop.

  • Click on the Scan button.
  • After the scan has finished, click on the Clean button.
  • Confirm each time with OK.
  • You will be prompted to restart your computer. A text file will open in Notepad after the restart (this is the log of what was removed), which you can save on your desktop.
  • Attach that log file to your reply by clicking the More Reply Options button to the lower-right of where you type in your reply.
  • If you lose that log file for any reason, you can find it at C:\AdwCleaner on your computer.
Download Junkware Removal Tool and save it on your desktop.
  • Shut down your anti-virus, anti-spyware, and firewall software now to avoid potential conflicts.

Thank you. Here are the two log files generated. After running Adwcleaner, the next time I opened internet explorer I received a notification saying that an unknown program wanted to change my default homepage to Bing. Is this normal? I closed the notification and it hasn't come back.

Thanks, that cleared up the Java/Obfuscator.W notice and MSERT is now reading as clean.

 

Also, I took the time to run a full scan with McAfee (last time I did a smart scan), and it came up with a "RDN/Generic Exploit!1m3" Trojan notice. McAfee quarantined it, and after I ran another full scan came back with 0 infections detected.

 

My computer was running really slow at one point, and I noticed about 80% of my RAM was in use, possibly because I hadn't restarted in a long time and have been opening and closing a lot of different programs (the issue cleared up after I restarted my computer). Anyway, because of this I went into Resource Monitor, and noticed I had multiple instances (about 10) of dllhost.exe shown running in memory in Resource Monitor, even though only one instance was shown running in Task Manager. I'm not really familiar with Resource Monitor so I'm not sure if this is normal or not.

You did have a dll file left over from a ZeroAccess Trojan infection. That could explain some of the issues you were experiencing.

Unless you are having problems, it is time to do the final steps.

Uninstall AdwCleaner:

  • Close all open programs and Internet browsers.
  • Double click on adwcleaner.exe to run the tool.
  • Click on the Uninstall button.
  • Confirm by clicking Yes.
Delete the following from your Desktop: (If they exist)

AdwCleaner.exe

Emsisoft Emergency Kit.lnk

FRST.exe

FRST64.exe

JRT.exe

JRT.txt

Anything else I had you use

Delete the following folders: (If they exist)

C:\AdwCleaner

C:\EEK

C:\FRST

Empty the Recycle Bin

Download to your Desktop:

- CCleaner Portable

  • UnZip CCleaner Portable to a folder on your Desktop named CCleaner
Run CCleaner
  • Open the CCleaner Folder on your Desktop and double click CCleaner.exe (32-bit) or CCleaner64.exe (64-bit)
  • The following should be selected by default, if not, please select:

    4l5a4i.png

  • Click 16jox2o.png and choose 5x3nu8.gif
  • Uncheck 2wlsw11.gif
  • Then go back to 2jb4qyb.gif and click nf47ev.gif to run it.
  • Exit CCleaner.
Turn off System restore to flush all your restore points then turn system restore back on. See How To Enable and Disable System Restore.

You can delete and uninstall any programs I had you download, that you do not wish to keep on the system.

Run Windows Update and update your Windows Operating System.

Install and run the Secunia Personal Software Inspector, this will inspect your system for software that is out-of-date and in need of updating. Update anything program/application detected as being out-dated.
