What is BackgroundContainer.dll?

The BackgroundContainer.dll error usually occurs on Windows startup and is associated with the Conduit Engine (or simply Conduit) browser hijacker, which promotes the search.conduit.com fake search engine. This browser hijacker is a potentially unwanted app (PUA). Most people download and install these rogue apps unintentionally.

BackgroundContainer.dll malware

To stop encountering the BackgroundContainer.dll (RunDLL) error, users must remove the Conduit browser hijacker, however, this is not the only reason why this (and other) PUAs of this type should be removed. Most browser hijackers promote fake search engines by changing browser settings such as the default homepage, new tab URL, and search engine. Therefore, people are forced to visit various sites (usually fake search engines) when they open the hijacked browser, new tab, or enter a search query into the URL bar. Typically, these settings cannot be undone or changed until the browser hijacker is uninstalled. Another problem with apps of this type is that they collect information relating to users' browsing habits. For example, they gather information such as IP addresses, geolocations, entered search queries, URLs of visited websites, and other details of this kind. Developers continually share the data with other parties who misuse it to generate revenue. There is a high probability that these people might include cyber criminals. If the installed anti-virus or anti-spyware suite has detected the BackgroundContainer.dll file as a threat, the browser hijacker should be removed by following the steps described in this article.

There are many browser hijackers available. They usually cause problems relating to privacy, browsing safety, however, some lead to other issues,  including the BackgroundContainer.dll error. Most of these apps deliver no real value and cause various issues. Therefore, do not use PUAs or have them installed.

How did BackgroundContainer.dll infiltrate my computer?

Most people download and install unwanted apps (such as browser hijackers) unintentionally. PUAs are generally downloaded and installed together with free software or through intrusive (deceptive) advertisements. Developers often include (bundle) unwanted apps into set-ups of other regular software that people download/install intentionally. Information about the bundling of PUAs into set-ups is usually hidden in settings such as "Custom", "Advanced", and so on. Not all people check these settings and then allow PUAs to be downloaded and installed together with other software. In other cases, people end up having unwanted apps installed when they click untrustworthy ads - when clicked, they run scripts that download and install PUAs.

How to avoid installation of malware?

Avoid using third party software installers and downloaders, Peer-to-Peer networks such as torrent clients, eMule (and other such tools), or unofficial and untrustworthy websites to download software. The safest way is to use official websites and direct download links. All downloads and installations should be handled properly - check all "Advanced", "Custom" and other similar settings/options that are included into set-ups, and deselect offers to download/install unwanted apps. It is not safe to click intrusive ads. Once clicked, they redirect users to untrustworthy and potentially malicious websites or cause unwanted downloads/installations. If a browser causes unwanted redirects or displays intrusive ads, check for installed unwanted extensions, add-ons, and plug-ins. Remove any suspicious/unwanted entries immediately. This should also be applied to programs of this kind installed on the operating system. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.
