This is the main goal of any potentially unwanted program because commercial content creators sponsor the distribution of such applications.

You can find a few tips for such manual changes below the article.
Because Alhea virus can display altered search results, you may be presented with the links to affiliated websites in priority. This way, third-party advertisers earn money by boosting traffic to the websites that are at the bottom of the page rank.
Unfortunately, these additional commercial redirects are more than annoying and disruptive. Each time you click on the link provided by this search, you risk exposing your computer to unsafe websites that are involved in the distribution of other PUPs. Moreover, security experts[1] have noticed the tendency of this hijacker to fill sites with commercial advertisements.
That's another marketing technique allowing advertisers to gain money via the pay-per-click (PPC) model[2], as well as help promoting various merchandise. Not to mention, it may also engage in tracking software and start analyzing your browsing habits.

Once a targeted system is affected, Alhea automatically installs cookies on all the browsers and starts collecting personally non-identifiable information (IP address, PC's location, email address, search terms, most visited websites, data entered in them, clicks, etc.) with an intention to send it to third-party advertisers who will analyze it and later provide the user with customized content.[3]
This issue regarding the PUP advertising tracking is disclosed on the Alhea website. In the Privacy Policy developers, Ego Cogito states about advertising cookies and other methods used to collect your data:
We do not collect your IP address and you do not have to register with Ego Cogito before we can collect this anonymous information. Ego Cogito websites do not require you to share personally identifiable information, such as your name or email address, for you to use Ego Cogito websites. Ego Cogito websites allocate an anonymous identification number to your requests and link the following information to that number: the date and time at which you visited the Ego Cogito website, the search terms, and the links which you clicked through.
If you are not keen on sharing information about you with third parties, as well as visiting doubtful websites on a daily basis, we highly recommend you to remove the PUP from the system. For that, our recommendation would be anti-malware tools, system cleaning utilities like SpyHunterCombo Cleaner, MalwarebytesMalwarebytes.

Keep in mind that Alhea has been labeled as a browser hijacker due to its capabilities to corrupt web browser's settings and initiate doubtful activities during people's browsing. One of the most prominent features that will leave no doubts that your web browser has been hijacked is a modification of a search provider and a default start page.

Never skip through freeware installation steps to control the installs
Browser hijacker modifies web browser's settings without computer user's knowledge. That's because it is usually spread in a bundle with freeware. This is because people still tend to install freeware without checking Advanced settings.
To prevent this cyber infection from happening, you should be more careful when installing anything on the system. It's a mistake to consider that free software downloaded from file sharing websites are entirely safe. Actually, such websites spread software packages by far the most frequently.
So whenever you decide to install freeware from the internet, make sure that you check Advanced/Custom options and untick all add-ons and plug-ins that are set to get installed by default on the initial installation setup. Also, pay attention to sources you get applications from, read the EULA of the website that promotes tools or programs.
