What is search25.co?
search25.co is a search engine developed by a company that claims to be helping owners of websites and web networks to generate revenue.
The site is similar to other popular and well-known search engines such as Google, Yahoo, Bing, etc. It claims to be a legitimate search engine, however, most browser hijacker developers claim to be legitimate and offer search engines that supposedly provide more relevant and improved results.
This search engine has a very minimalistic design that contains only a logo and a search box. Once a search query is made, it provides results generated by the search25.co search engine. Most browser hijackers use their associated fake search engines to provide misleading or unwanted results (or redirects).
This might also be the case when using the search25.co search engine. This is how developers generate revenue - by encouraging users to click unwanted/misleading results.
Furthermore, visiting unwanted websites can lead to users being tricked into downloading unwanted or potentially malicious software and their browsing experience can also be diminished in other ways. You may begin to see various pop-up ads or even have your computer infected.
Most fake search engines track users by collecting information regarding their browsing habits. Recorded information might include visited websites, search queries, IP addresses, etc. There are many cases whereby this collected data is shared with third parties (potentially, cyber criminals). Therefore, you could experience privacy issues and other similar problems.

Once your browser is hijacked by search25.co, the search engine, homepage, and new tabs settings are replaced with the search25.co URL. This is not the only fake search engine developed by the same company. Take search14.co, for example - it looks almost identical and serves the same purpose.
Other examples of similar fake search engines with the same purpose (to generate revenue by providing misleading/unwanted redirects/results) are: searchdims.network, sleepshadow.com, and smartsearch.pw
How did search25.co install on my computer?
In most cases, browsers are hijacked when installing other software. This is a well-known method called "bundling". In this way, developers hide potentially unwanted programs within the installation processes of other software.
Furthermore, many users install software without carefully checking all available options such as "Custom" or "Advanced" - this is how browser hijackers are installed. They are also installed through intrusive ads. When clicked, these ads usually redirect to malicious websites and execute scripts that stealthily download and install unwanted programs.
Browser hijackers are also installed when an attachment in an email from unknown sender is clicked, when you visit an infected website, download software from a file-sharing site, or via torrents. It can also happen when you click a "Download" (or similar) button when visiting an untrustworthy website or when using a third party software downloader/installer.
How to avoid installation of potentially unwanted applications?
Check all available options such as "Custom" or "Advanced" of the software installation process, especially if the software you install is free or ad-supportive. If you notice that there is additional software or 'special features' offered, deselect it. Do not download software using torrents or from unofficial websites and use direct download links only.
Avoid using third party software downloaders or installers, since as a rule, they are monetized by promoting potentially unwanted software.
Avoid visiting untrustworthy websites and clicking ads (or "Download") buttons on them. Finally, keep your antivirus software enabled. If your computer is already infected with browser hijackers, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
