Muti-webtool browser hijacker removal instructions

What is Muti-webtool?

Like most browser hijackers, Muti-webtool promotes a fake search engine (its address). Additionally, it collects browsing data. Typically, users do not download and install browser hijackers knowingly/on purpose. Therefore, Muti-webtool is categorized as potentially unwanted application (PUA).

tailsearch.com redirects to google.com

Muti-webtool promotes the tailsearch.com address. Typically, apps of this type do that by assigning the address of a certain fake search engine as the address of a default search engine, homepage and new tab. Although, it is known that Muti-webtool does not always change the aforementioned settings to tailsearch.com - in such cases it opens the tailsearch.com address only when its users enter search queries into URL bar. Tailsearch.com is a fake search engine because it does not generate unique results. It displays results generated either by Google or Bing - it depends on user's geolocation. It is worthwhile to mention that tailsearch.com redirects to bing.com via my-search.com and search-checker.com - other unreliable addresses. In most cases before being able to remove address of a fake search engine from browser settings users need to uninstall a browser hijacker that changes those settings. It is because apps of this type prevent users from doing any modifications in the aforementioned settings as long as they are installed. Although, it is not the only reason not to have any browser hijacker installed on a browser and/or computer. Quit often apps of this type are designed to collect information related to user's browsing habits. For example, IP addresses, entered search queries, addresses of visited/opened websites, geolocations. Although, some of them are capable of accessing sensitive, personal details as well. Moreover, collected data may be sold to third parties (potentially cyber criminals) or misused to generate revenue in other ways. It means that users may encounter problems related to online privacy, browsing safety, or even become victims of identity theft.

There are many various browser hijackers on the Internet, some examples are IStreamingSearch, Converterz-Search and MySearchConverter. However, most of them are designed to do the same thing: to promote some fake search engine and/or collect various data. It is worthwhile to mention that browser hijackers tend to be advertised as useful apps that supposed to deliver various features, improve browsing experience, etc. However, most of them are useless and can be the reason behind various issues.

How did Muti-webtool install on my computer?

Very often users download and install browser hijackers (and other types of PUAs) through setups of other programs. To be more precise, together with programs that have PUAs included in their download and/or installation setups as additional offers. Usually, those offers can be declined by unticking certain checkboxes or "Custom", "Advanced" or other settings that are available in setups. Although, quite often users leave those settings unchanged and that is how they allow for included PUAs to be downloaded and/or installed too. This distribution for PUAs is known as "bundling". Also, unwanted downloads or installations can be caused by clicking deceptive advertisements - by clicking ads that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

It is recommended to download programs (and files) from trustworthy, official websites and via direct download links. Other sources, tools like third party downloaders (and installers), torrent clients, eMule (and other Peer-to-Peer networks), unofficial pages can be used to promote unwanted apps. Also, it is advised to always check download and installation setups for checkboxes, "Advanced", "Custom" and other similar settings to see if they contain offers to download and/or install additionally included (unwanted) apps. Intrusive advertisements that are shown on shady pages often tend to be designed to open untrustworthy websites or cause downloads, installations of unwanted applications. For these reasons it is not safe to click such ads. If there are any unknown, unwanted and/or suspicious extensions, plug-ins or add-ons installed on a browser (or programs of this kind installed on the operating system), then they should be uninstalled. If your computer is already infected with Muti-webtool, we recommend running a scan with Malwarebytes for Windows to automatically eliminate this browser hijacker.
