I have the same problem with this topic! How to resolve BackgroundContainer.dll error on startup?

The thing is i did everything that says in answer but

i)I found nothing when i started regedit.exe and searched (F3 or CTRL+F) for BackgroundContainer.dll

ii)I made a full scan with AntiVirus Scanner like Microsoft Security Essentials/ Defender and also i scaned my PC with Malwarebytes' Anti-Malware,but i found nothing.

So this pop up message on start up keep appeared!

Thank you!

Just becuase the existing answer(s) don't work for you doesn't mean you should post the same question again. Please add comments or perhaps earn some rep and post a bounty on the existing question, pointing out what you tried and how it didn't work for you. –  Ƭᴇcʜιᴇ007 Oct 19 '13 at 22:10

The idea of a duplicate is that the same issue shouldn't be posted in two places unless it's a different problem. There's no need to have 4 posts all with the exact same issue. –  Moses Oct 19 '13 at 23:16
    
@ManolisKaragiannis No problems. :) With the other question, what you did was post your 'comment' as as 'answer', so it was removed. I can see how the generic comment provided on removal could be confusing though. –  Ƭᴇcʜιᴇ007 Oct 19 '13 at 23:35

When the exploit was cleaned up, it left behind a scheduled task which loads when Windows starts. Naturally, the task can no longer find the program it was going to run.
