How to uninstall the DynoAppSearch browser hijacker

Also Known As: dynoappsearch.com redirect
Damage level: Medium

What is DynoAppSearch?

DynoAppSearch is a potentially unwanted application (PUA), a browser hijacker. It promotes dynoappsearch.com (a fake search engine) by changing browser settings and gathers information relating to users' browsing activity. In most cases, people download and install apps of this type inadvertently.

dynoappsearch.com browser hijacker

Like most browser hijackers, DynoAppSearch promotes a fake search engine by modifying settings such as the address of the default search engine, homepage, and new tab. After installation, DynoAppSearch assigns them to dynoappsearch.com.

In this way, PUAs ensure that users visit a specific address when they open a browser, new tab or enter search queries into the URL bar. In most cases, it is impossible to remove the address of the fake search engine appointed by the browser hijacker without first uninstalling it.

In this case, dynoappsearch.com can be removed from the aforementioned settings only after uninstallation of DynoAppSearch. Search engines such as dynoappsearch.com are classified as fake, since they provide results generated by other, usually legitimate, search engines (i.e., they do not generate unique results).

Note that dynoappsearch.com provides results generated by Bing and simply redirects users to bing.com. This is not the only reason to uninstall DynoAppSearch and avoid dynoappsearch.com. Typically, browser hijackers gather data relating to users' browsing habits such as IP addresses, entered search queries, addresses of opened sites, geolocations, and other data.

Some browser hijackers can access and record private, sensitive details. Developers generate revenue by selling the information to third parties (cyber criminals) and misusing it in various ways. PUAs can thus cause problems relating to browsing safety, privacy, and it is possible that gathered data will be misused to steal users' identities.

Therefore, we strongly recommend against downloading or installing this software.

There are many browser hijackers online (e.g., Easy Email Login, Template Finder Now, and Breaking News Plus). Most promote fake search engines and collect browsing data.

These apps are advertised as useful and supposedly deliver useful features, however, few operate as promised and simply cause problems. If DynoAppSearch and other PUAs are already installed on the browser and/or computer, remove them immediately.

How did DynoAppSearch install on my computer?

Typically, browser hijackers such as DynoAppSearch and other PUAs are installed through clicked deceptive advertisements or when software developers distribute them using the "bundling" method. Developers use this technique to trick people into downloading and/or installing unwanted apps with other software.

Typically, developers include PUAs into the download/installation set-ups of other programs and hope that people will fail to decline offers to download and install them. In most cases, the offers can be found in "Custom", "Advanced" and other similar settings of the set-ups.

People who download and install programs without checking and changing the settings often allow included PUAs to be downloaded and installed through the set-ups.

How to avoid installation of potentially unwanted applications

Check "Custom", "Advanced", "Manual" and other settings of the download and/or installation set-ups, especially if the software is free. Dismiss any offers to download or install additional, unwanted software.

Do not download or install software through untrusted, unofficial websites, torrent clients, eMule (and other Peer-to-Peer networks), third party downloaders, installers, and so on. The safest way to download files and programs is using official pages and direct links. Advertisements that are shown on dubious pages should not be clicked.

Typically, they open potentially malicious pages or cause download/installation of unwanted programs. Remove any unwanted, suspicious extensions, plug-ins and add-ons already installed on the browser. The same should be applied to software of this kind that is installed on the operating system.

If your computer is already infected with DynoAppSearch, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate this browser hijacker.
