Search-7.com redirect removal instructions

What is search-7.com?

Search-7.com is an address of a fake search engine. Typically, fake search engines are promoted through browser hijackers - potentially unwanted applications (PUAs) that are designed to hijack browsers by modifying some of their settings. One of the apps which is designed to change browser's settings to search-7.com is called Convlus App. Although, it is very likely that it is not the only app designed to promote this fake search engine. It is worthwhile to mention that browser hijackers often are designed to gather various data as well. They are categorized as PUAs because most users download and install them unintentionally, unknowingly.

search-7.com browser hijacker

As a rule, a browser hijacker promotes fake search engine by assigning its addresses as a homepage, default search engine and address of a new tab. Simply said, such apps are designed to ensure that users would visit a certain address when they open a browser, new tab and enter search queries into browser's URL bar. In this case Convlus App (or some PUA with a different name) changes the aforementioned settings to search-7.com. It is worthwhile to mention that results generated by search-7.com are displayed only after redirecting users to websearch1.com, another shady address. Fake search engines like search-7.com should not be used/trusted because they can generate results that would include links to unreliable websites. Typically, changes made by a browser hijacker can be undone only after uninstallation of that app. In this particular case search-7.com can be stopped from being opened on the aforementioned occasions only after uninstalling Convlus App or other PUA that is designed to promote this address. Another reason to uninstall any installed browser hijacker is that such apps often are designed to operate as information tracking tools - they collect various data. More often than not they target browsing data (e.g., addresses of visited websites, entered search queries, IP addresses, geolocations). Although, a browser hijacker can be capable of accessing personal, sensitive data as well. As if it were not enough, data collected by an app of this type may be misused to generate revenue. Its developers may sell gathered information to third parties (potentially cyber criminals) or misuse it in other ways. It means that users might become victims of identity theft, experience problems related to online privacy, browsing safety and/or other issues.

A couple examples of other fake search engines are gooogle.page, s3redirect.com and pdfsrch.com. Typically, such addresses appear in browser's settings only after installation of some browser hijacker. Usually such apps supposed to include some features, improve browsing experience, etc. Although, most of them are not only useless but can be the reason behind various issues. If a browser is hijacked by such PUA, then that app should be removed from it as soon as possible.

How did search-7.com install on my computer?

In most cases users cause download and/or installation of a browser hijacker (or other type of PUA) when it is included in a download and/or installation setup of some other program. Usually offers to download and/or install extra apps are mentioned in setup's settings like "Advanced", "Custom", "Manual". Although, not all users change those settings when they download and/or install programs. By leaving the aforementioned settings unchanged users allow for included app (or apps) to be downloaded and/or installed alongside with a desired software. This method to distribute PUAs is called "bundling". Also, sometimes users download and/or install unwanted apps by clicking deceptive advertisements that are designed to execute certain scripts.

How to avoid installation of potentially unwanted applications?

Unwanted downloads, installations can be prevented by declining offers to download and/or install unwanted apps in setup's settings like "Advanced", "Custom". If a setup has such settings in it, then it is very likely that it will include offers to download and/or install PUAs as well. Another way to prevent such downloads and/or installations is not to use unofficial pages, third party downloaders, installers, Peer-to-Peer networks (e.g., torrent clients, eMule) and/or other channels as tools to download and/or install files, programs. Files and programs should be downloaded only from legitimate, official sites and via direct links. As mentioned in the previous paragraph, deceptive ads can cause unwanted downloads and/or installations too. Therefore, they should not be clicked. Typically, such ads appear on unreliable, shady websites (e.g., on pages related to gambling, adult dating, pornography). If there are any unwanted apps (add-ons, extensions, plug-ins) already installed on a web browser or programs of this kind installed on the operating system, then it is recommended to eliminate (uninstall) them as soon as possible. If your computer is already infected with browser hijackers, we recommend running a scan with Malwarebytes for Windows to automatically eliminate it.
