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.

We get asked this a lot, so we are putting it here: Removing parasite manually may take hours and damage your system in the process. We recommend downloading SpyHunter to see if it can detect parasite files for you.

Press CTRL + SHIFT + ESC at the same time and go to the Processes Tab (the “Details” Tab on Win 8 and 10). Try to determine which processes are dangerous. 


Right click on each of them and select Open File Location. Then scan the files with our free online virus scanner:

After you open their folder, end the processes that are infected, then delete their folders. 

Note: If you are sure something is part of the infection – delete it, even if the scanner doesn’t flag it. No anti-virus program can detect all infections. 


Hold together the Start Key and R. Type appwiz.cpl –> OK.


You are now in the Control Panel. Look for suspicious entries. Uninstall it/them.

Type msconfig in the search field and hit enter. A window will pop-up:

To remove parasite on your own, you may have to meddle with system files and registries. If you were to do this, you need to be extremely careful, because you may damage your system.

If you want to avoid the risk, we recommend downloading SpyHunter
a professional malware removal tool.
