Ceesty Virus


Ceesty is a browser hijacking application that can manipulate the users’ default web browser. Ceesty can replace the main search engine tool, install a new toolbar, or change the homepage URL without an approval.

The Ceesty.com Virus will display pop up ads and messages

Perhaps your browser (be it Edge, Chrome, Firefox, etc.) has recently started to behave quite oddly. A new and unfamiliar domain might have replaced your favorite homepage domain. Or perhaps a lot of pop-up ads, banners and notifications have started to appear on every web page that you visit. Also, probably, a new search engine has set itself as the default one and has now started to redirect you to web addresses that are irrelevant to your actual searches. 

If the above symptoms are familiar to you, it is highly likely that your PC has been infected with Ceesty. All the important information about this kind of infection has been collected in the following article. In addition, we have assembled a removal guide to help you uninstall this irritating software and remove its frustrating modifications.

What kind of program is Ceesty?

This type of program is basically a browser hijacker. There are many different browser hijackers, but they all have the same way of working and the same features. In general, browser hijackers operate as online advertising tools. They are programmed to integrate with the main web browser in the system and to display ads on its screen in whatever possible way. In order to do that, programs like Ceesty use some techniques that ensure maximum ad exposure. They tend to introduce changes in the browser’s homepage, the search engine, the new tab page, and the taskbar by installing components that generate ads and redirect to pages with sponsored commercials.

The problem is that these changes and the ads that appear may disturb your whole browsing activity. You may not be able to open the websites that you want because there are always redirections to other websites. Some experts consider this behavior to be very intrusive and irritating, that is why they usually suggest that web users remove these programs and uninstall their changes.

The representatives of the browser hijacker category, however, have never been classified as viruses despite being considered to be potentially unwanted. This is because, as a matter of fact, programs like Ceesty can’t do anything malicious, such as steal information, lock personal files or crash your entire computer. Such actions are the specialty of threats like Ransomware and Trojans.

Some of the browser hijackers’ activities, however, could still be considered shady and doubtful. An example is the page-redirect activity that can land users on different web locations. Such redirects may potentially lead phishing pages or online places where real security hazards including the aforementioned Ransomware or other viruses can lurk. Unfortunately, you have no control over this activity as long as the browser hijacker is operating in your system. In this respect, there is only one good option – to uninstall the unwanted software and to regain full control over your browser by resetting its settings.
