removal by Alice Woods - -   Also known as Cassiopessa | Type: Browser Hijackers

Cassiopesa is a Chromium-based browser categorized as a potentially unwanted program that makes unwanted changes on the computer

Cassiopesa.com

Cassiopesa.com is a domain name that users will see on their Google Chrome, Safari, Internet Explorer, Mozilla Firefox, or another browser after they get hijacked by a potentially unwanted application. The program comes in the form of a Chromium-based browser and initiates all the other changes at once.

Potentially unwanted programs[1] (or PUPs for short) usually come bundled inside a software package downloaded from third-party hosting sites. Unfortunately, users might not be presented with the full list of the apps that are about to be installed unless the Advanced/Custom settings are picked. Soon after that, they will notice the Cassiopesa.com hijack and that their default web browser that opens .html, .php and other webpage-associated extensions changed to a customized version of Chromium.

Beware that Cassiopesa may cause various unwanted issues during your browsing. For example, it may initiate continuous redirects to unknown and suspicious websites, diminish web browser performance, or may even track your online activities. Therefore, if you noticed that your default web browser changed without your permission, you should immediately proceed with Cassiopesa.com removal from your system.

Name Cassiopesa
Type Potentially unwanted program, browser hijacker
Category Browser based on Chromium project
Search engine set to Cassiopesa.com
Symptoms Hijacked web browsers, sponsored links, intrusive ads, redirects, etc.
Potential risks Installation of bogus software, malware infection, information disclosure to unknown parties, etc.
Termination To delete the browser automatically, scan your system with Reimage Reimage Cleaner or make use of our manual removal guide below

It is worth mentioning that Chromium is a legitimate web browser and an open-source project by Google. Unfortunately, many businesses that specialize is online advertising adopted it and turned it into potentially unwanted programs. Here are a few examples of potentially malicious browsers that work similarly to Cassiopesa:

  • Citrio
  • Chroomium
  • Qword
  • WebDiscover
  • Yandex
  • Fusion, etc.

The primary feature of Cassiopesa.com is to display the promoted sites in all possible ways. For that, the developers employ software bundling[2] in order to distribute the app to as many people as possible, which consequently performs changes to other web browsers and installs itself as a default one.

Users then can see a variety of sponsored links at the top of the search results that lead to affiliated sites. Besides, users might encounter pop-ups, deals, offers, in-text links, and other ads from Cassiopesa.com that might cover the underlying content of all visited sites, diminishing the web browser experience.

In some cases, the ads that offer bogus system scanners and fake driver updates might be inserted directly into the startup page. In such a way, the developers guarantee that the sponsored content will be viewed by millions, consequently guaranteeing revenue for themselves. Unfortunately, Cassiopesa virus victims will struggle with never-ending ads and unwanted browser changes, and might as well have troubles while trying to get rid of the PUP.

Cassiopesa hijack
Cassiopesa is a potentially unwanted application that travels inside software bundles, so users rarely notice the point of entry

Besides, Cassiopesa.com  is spread along with tracking cookies,[3] which may collect and store various information about the users, such as IP address, email address, PC location, search terms, websites visited, data entered in them, clicks, browser type, language and so on.

Therefore, by keeping Cassiopesa browser hijacker on your computer you risk losing personally and non-personally identifiable information, landing on suspicious websites, infecting your machine with other suspicious programs like scareware and even injecting malware without noticing it.

To conclude, our team, along with experts from Zondervirus.nl[4] recommend users to remove Cassiopesa.com from their systems as soon as possible. The elimination can be performed by using automated security tools like Reimage Reimage Cleaner or by employing manual removal instructions at the bottom of this article.

Browser hijackers are distributed by using deceptive methods

Potentially unwanted programs are called in this way mainly because of the way they are distributed – users often find such apps installed without their permission. PUPs are inserted into a single software package, and optional components are often hidden from users' eyes purposely. This method, also often called as software bundling, is deceptive and unfair, although users are often accused of negligence and that they themselves failed to read the installation instruction properly.

Such software packages are usually promoted via popular and reputable download websites, including download.com, softonic.com, soft32.com, cnet.com, etc. By promoting optional applications within the freeware installers, these sites monetize effectively, and also offer freeware developers some share. Therefore, all parties are interested in as many users to install the optional components as possible.

No matter how attractively the optional components may be introduced, don't forget that the majority of them are adware, browser hijackers or other PUPs. To protect your computer from unwanted ads and redirects, you should opt-out of all attachments that are traveling with your selected freeware. Therefore, you should always opt for Advanced/Custom settings, decline all the deals or offers, and watch out for fine print along with pre-selected boxes to avoid PUP installation.

You can terminate Cassiopesa either manually or automatically

If Cassiopesa.com virus has already been downloaded to your computer as a reliable search engine, you should stay away from it. Otherwise, you may notice such unwanted activities as redirects to unknown websites, tons of annoying pop-up ads, and even browser crashes.

The easiest way to remove Cassiopesa.com from your system is by using reputable anti-malware software that can detect and terminate potentially unwanted programs (some AV vendors include the scan as an optional feature, as PUPs are not usually treated as malware). Alternatively, you can also employ our manual Cassiopesa removal instructions below and find all the unwanted programs yourself. Be warned that it might not be an easy task, especially if your computer is flooded with multiple unwanted applications.

Because Cassiopesa is a browser hijacker, it modified the settings of Mozilla Firefox, Safari, Google Chrome, and other installed browsers. Therefore, you should also reset the settings to make sure that unwanted activity does not come back.
