Remove OneStart unwanted application

OneStart is a browser that’s advertised as an AI (Artificial Intelligence)-assisted browser. It’s based on the Chromium open-source project. However, because it’s bundled with other programs, it’s considered to be a potentially unwanted program (PUP). It’s not a dangerous program, nor will it harm the computer. However, if you find it installed on your computer, you may not even remember installing it because it used a deceptive installation method. 

 

 

OneStart is a Chromium-based browser that offers various AI features for supposedly more convenient browsing. One of them is a shortcut widget for ChatGPT. While it’s a legitimate browser, it does display some questionable behavior that makes it a PUP. Specifically, its biggest issue is the way it installs. It’s distributed via what’s known as software bundling, an installation method that allows programs to be installed without users’ explicit permission.

We should also mention that searches performed via this browser will first redirect to onestart.ai and then land on search.yahoo.com.

While OneStart unwanted application is not directly dangerous, programs that try to install using deceptive methods have no place on your computer, whether you find the program itself to be useful or not.

Potentially unwanted programs in general have a lot of unwanted features, including unnecessary changes to a browser’s settings, a never-ending stream of ads, tracking, etc. While they are not considered to be particularly dangerous, keeping PUPs installed is not a good idea. If you have an anti-virus program installed, it should detect PUPs as threats and recommend that you delete them.

How does the OneStart unwanted application install on users’ computers?

The reason OneStart is classified as a potentially unwanted application is because it’s bundled together with other popular free programs. This is a method that allows programs to be installed without explicit permission, to essentially sneak past users. This is why you may not remember installing it if you find it on your computer.

The way software bundling works is additional offers are added to popular free programs. It’s usually adware and browser hijackers that get added but the occasional legitimate program also gets added. When something is added to a program as an extra offer, it’s set to install alongside the program automatically, without requiring explicit permission from users. Users usually aren’t even aware of any extra offers because they’re hidden in settings users don’t normally use. While the extra offers are optional, deselecting them is made purposely difficult, which is why software bundling is considered to be a controversial installation method. It’s common for programs that use it to be detected as potential threats by anti-virus programs.

When installing programs, especially free popular ones, it’s important to always deselect all offers to prevent unauthorized installations and stop your computer from being cluttered with junk. To do that, make sure to use Advanced (Custom) settings when given the option during program installation. The installation window will recommend using Default settings because it’s quicker but these settings make all offers hidden and authorize their installations. Advanced settings, on the other hand, make all offers visible and give you the option to deselect all of them. All you need to do is uncheck the boxes of those offers.

We also recommend researching a program before installing it in the future. Free program download sites are full of unwanted programs, disguised as useful ones to trick users into installing them. A simple search with Google or another search engine is often enough to determine whether a program is safe to download/install.

Should you remove OneStart unwanted application from your computer?

If you find it installed on your computer but have no recollection of installing it, you should remove OneStart unwanted application. While the program is not going to harm your computer, it was installed without your explicit permission and such programs do not belong on your device. It’s also detected as a threat by many anti-virus programs. Thus, we strongly recommend you delete OneStart unwanted application. Using an anti-virus program is a good idea because it could be somewhat difficult to get rid of the PUP manually.
