How to resolve BackgroundContainer.dll error on startup?

I didn't find any entries relating to this in the registry, but I did find it in Task Scheduler.

• Open Control Panel
• Open Administrative Tools
• Open Task Scheduler
• Click on Task Scheduler Library
• Scroll through the list until you find BackgroundContainer
• Right click on the entry
• Click on Delete on the menu that pops up.
• Close all windows, reboot computer

The result is no more error on start up.

This was a malware. It was removed by your AntiVirus Scanner, but the registry entries are still present to start the malware at startup.

Start regedit.exe and search (F3 or CTRL+F) for BackgroundContainer.dll and delete all entries you find.

1. Press Windows Key + R
2. In run dialog, type regedit and press Enter
3. Go to HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
4. Delete BackgroundContainer.dll
5. Reboot PC
