How to remove unwnated apps desinged to open oundoutth.biz?

Also Known As: Ads by oundoutth.biz
Type: Adware
Damage level: Medium

What is oundoutth[.]biz?

It is highly advisable not to trust oundoutth[.]biz or websites it promotes. There are many sites like this on the Internet, for example, wholecommonposts[.]com, besty-deals[.]com, and n02[.]biz.

Usually, users do not visit such sites on purpose. These pages get opened through deceptive advertisements, other untrustworthy sites, or potentially unwanted applications (PUAs).

It is uncommon for PUAs to be downloaded and installed intentionally. That is the reason why they are called potentially unwanted.

It is noteworthy that apps of this kind can be designed to collect various data and (or) display advertisements.

oundoutth[.]biz pop-up redirects

In most cases, oundoutth[.]biz and other similar pages open a couple of other untrustworthy pages, or they load dubious content (it depends on the IP address of their visitors). It is common that pages opened through sites like oundoutth[.]biz are various download pages for adware-type apps, browser hijackers or other unwanted apps, scams designed to extract money, personal information (e.g., "Microsoft Security Essentials Alert", "Chance To Win The New iPad Pro"), and so on.

Therefore, it is recommended not to trust both oundoutth[.]biz and websites that it is designed to open. Another important thing about oundoutth[.]biz is that this page displays a message encouraging to click the "Allow" button to continue. It uses a clickbait technique (suggests that it can be loaded by clicking the aforementioned button) to trick visitors into allowing it to show its notifications.

Typically, notifications displayed by pages like oundoutth[.]biz contain deceptive advertisements, unreliable links, or other questionable content. Therefore, untrustworthy websites (including oundoutth[.]biz) should never be allowed to show notifications.

Potentially unwanted applications can collect various data and (or) generate advertisements. Most of them target browsing-related data like IP addresses, entered search queries, geolocations, visited addresses, and so on. Some of them gather personal data. It is not safe to have such PUAs installed because gathered data may be sold to third parties (potentially cybercriminals), or monetized in other ways.

Ads that PUAs generate are coupons, pop-up ads, surveys, banners, and other types of ads. It is common that those ads are used to promote shady, potentially malicious pages. It is important to mention that some of those ads may execute certain scripts designed to download or even install unwanted software.

To summarize, PUAs can be the reason behind issues related to online privacy, browsing safety, or even identity fraud. Therefore, apps of this type should never be downloaded and installed.

Pages like oundoutth[.]biz should not be trusted too. Users who have apps that open pages like oundoutth[.]biz installed on browsers or computers should remove them.

How did adware install on my computer?

One of the deceptive ways to trick users into downloading or installing PUAs is to bundle them with other programs to include them in downloaders or installers as additional offers. Not all users know that certain downloaders and installers have settings that can be used to decline unwanted offers and unknowingly agree with them.

Typically, PUAs can be opted out via "Advanced", "Custom" or other settings, or by unticking ticked checkboxes. Another deceptive way to distribute PUAs is to design advertisements to execute certain scripts. Users cause unexpected downloads, installations by clicking those advertisements (usually, they appear on dubious sites).

How to avoid installation of potentially unwanted applications?

It is recommended not to trust files or programs downloaded using third-party downloaders (or installed via third-party installers), Peer-to-Peer networks like torrent clients, eMule, from unofficial websites, and so on. They can be malicious or designed to generate ads, hijack browsers. Apps (and files) should be downloaded from official, trustworthy websites and via direct links.

Downloads and installations should not be finished without checking downloaders, installers for bundled apps. Usually, they are mentioned and can be opted out via "Custom", "Advanced" and other settings or checkboxes. Additionally, it is advisable to avoid clicking ads on questionable websites.

It is common that those ads open questionable websites. Sometimes users who click those ads cause unwanted downloads, installations.

All suspicious, unwanted extensions, add-ons, or plug-ins installed on a web browser and programs of this kind installed on the operating system should be removed. If your computer is already infected with rogue applications, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
