Hello,

 

when I start my computer or log in (Windows 7), a window continuously appears on my desktop telling me:

 

RunDLL

"There was a problem starting

C:\Users\Username\AppData\Local\Conduit\BackgroundContainer\BackgroundContainer.dll

The specified module could not be found."

 

I suspect that my new computer has already been infected. I read about a similar case here: http://www.bleepingcomputer.com/forums/t/499644/run-dll-error-the-specified-module-could-not-be-found/ .

 

My browser is sometimes slower than usual. Logging in takes longer than usual. Also, a few times I've noticed some flickering windows when they are active.

 

Hopefully someone can help me?

The file in the error message is related to Conduit, a toolbar engine installed (bundled) alongside many free applications which allows users to add applications directly to their browser without a community toolbar. Conduit offers a distribution option for Conduit-powered offerings and is used in order to generate ad revenue for the company. While not explicitly malware, it is often installed stealthily without knowledge or consent from the end user and is considered a Potentially Unwanted Program (PUP).

After using anti-virus and other security scanning tools to remove adware, PUPs and malware it is not uncommon to find remnants of startup and scheduled task registry keys when booting up your computer.

Windows is trying to load this file but cannot locate it since the file may have been removed inadvertently, during the uninstallation of a program or after performing a scan with security tools. However, an associated orphaned registry entry (value) still exists and is telling Windows to load the file when you boot up. Since the file no longer exists, you need to remove this registry entry so Windows stops searching for the file when it loads.

Conduit is a toolbar engine installed (bundled) alongside many free applications which allows users to add applications directly to their browser without a community toolbar. While not explicitly malware, it is often installed stealthily without knowledge or consent from the end user and is considered a Potentially Unwanted Program (PUP) since it is responisble for installing a lot of other junkware.

After doing the above...continue as follows:

Please download and use the following tools (in the order listed) which will search for and remove many potentially unwanted programs (PUPs), adware, toolbars, browser hijackers, extensions, add-ons and other junkware as well as related registry entries (values, keys) and remnants.

RKill created by Grinler (aka Lawrence Abrams), the site owner of BleepingComputer.
AdwCleaner created by Xplode.
Junkware Removal Tool created by thisisu.

1. Double-click on RKill to launch the tool. A black DOS box will briefly flash and then disappear. This is normal and indicates the tool ran successfully. A log file will be created and saved to the root directory, C:\RKill.log. Copy and paste the contents of RKill.log in your next reply.

Important: Do not reboot your computer until you complete the next step.

2. Double-click on AdwCleaner.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
  • Click on the Scan button.
  • AdwCleaner will begin...be patient as the scan may take some time to complete.
  • After the scan has finished, click on the Report button...a logfile (AdwCleaner[R0].txt) will open in Notepad for review.
  • After reviewing the log, click on the Clean button.
  • Press OK when asked to close all programs and follow the onscreen prompts.
  • Press OK again to allow AdwCleaner to restart the computer and complete the removal process.
  • After rebooting, a logfile report (AdwCleaner[S0].txt) will open automatically.
  • Copy and paste the contents of that logfile in your next reply.
  • A copy of all logfiles are saved in the C:\AdwCleaner folder which was created when running the tool.
-- Note: The contents of the AdwCleaner log file may be confusing. Unless you see a program name that you recognize and know should not be removed, don't worry about it. If you see an entry you want to keep, return to AdwCleaner before cleaning...all detected items will be listed (and checked) in each tab. Click on each one and uncheck any items you want to keep (except you cannot uncheck Chrome and Firefox preferences lines).


Close all open programs and shut down any protection/security software to avoid potential conflicts.

3. Double-click on JRT.exe to run the tool.
Vista/Windows 7/8 users right-click and select Run As Administrator.
  • The tool will open and start scanning your system.
  • Please be patient as this can take a while to complete depending on your system's specifications.
  • On completion, a log file named JRT.txt will automatically open and be saved to your Desktop.
  • Copy and paste the contents of JRT.txt in your next reply.
