Some of the most common issues that web users face nowadays are usually advert-related. And this is not surprising, because there are thousands of websites and ad-generating tools which use some quite aggressive and irritating advertising approaches to promote different products and services on the users’ screen during their regular browsing sessions. Installing an ad-blocker, in most of the cases, may be enough to block the nagging pop-ups, banners and blinking boxes if they are coming from certain ad-supported websites. However, if you have accidentally installed an ad-generating or a page-redirecting software such as Penint on your browser, no ad-blocker can save you from the potentially unwanted stream of irritating commercial messages and search engine and homepage changes that this type of software may trigger in your IE, Chrome, Firefox or any other browser. In the cyber circles, such software is known as a browser hijacker and is generally not considered as a computer virus or a serious computer threat (such as Ransomware, Trojans, Spyware, etc.) However, its presence on the system is considered to be potentially unwanted as it is usually related to some intrusive browser changes which may include the installation of new search engine tools and toolbars, homepage replacements, automatic page-redirects and aggressive generation of sponsored advertisements. Fortunately, you can easily detect a browser hijacker because the moment it latches onto your main browsing app (it could be Chrome, Firefox, Explorer, etc.) it starts to promote to some predefined web pages, offers, tools, pay-per-click links and banners by aggressively prompting you to click on them. In the next lines, you will find some more information about the nature of the browser hijackers in general, as well as about the specifics of Penint, which is a new addition to this irritating type of software. In case that this particular hijacker is currently inside your system and you are facing difficulties with removing its ads or uninstalling its settings, within the removal guide below, you will find instructions that will help you safely eliminate everything.

Keep away from the pop-ups that Penint may display – they may not always be safe!

The main goal of most browser hijackers is to promote some third-party messages on the users’ screens because this is how this software earns revenue for its developers. Most of the web users, however, find it quite irritating and disturbing to constantly have their screen filled with sponsored ads, banners, redirect links and similar commercials. What is more, many people fear that such randomly displayed messages may contain viruses and may lead to a close encounter with nasty threats from the rank of Ransomware, Spyware or Trojan Horses. Now, this fear of a potential encounter with malware is usually exaggerated because the browser hijackers are typically legitimate advertising tools which display generally safe commercials and are not interested in infecting your system. However, people with malicious intentions oftentimes use fake ads and misleading links and may find ways to sneak hazardous content inside the randomly displayed messages that software like Penint may stream on your screen. For this reason, the presence of such software is considered to be undesirable on your computer. What is more, if not removed and uninstalled completely, the browser hijacker may heavily disturb your web surfing experience in the long run and may expose you to potentially hazardous web locations.

Removing Penint

Step 1: Checking the Task Manager

Open your Task Manager by using the Ctrl + Shift + Esc keys and go to the Processes tab. Look for any suspicious processes. For example, any unfamiliar process that uses high amounts of RAM and/or CPU. If you aren’t sure if a certain process comes from malware, tell us in the comments.

Right-click on any process that you consider shady and select Open File Location. Delete anything from the file location of the process.

Step 2: Disabling Startup programs

Step 3: Uninstalling unwanted programs

Go to Start Menu > Control Panel > Uninstall a Program. Click on Installed On to sort the entries by date from most recent to oldest and look through the programs that come at the top of the list.

You will also have to uninstall any undesirable browser extensions from your browser programs. Here’s how to do that for some of the more popular browsers:


Open Chrome and open its main menu. Go to More Tools > Extensions. Look through the list of extensions and uninstall any that you think could be suspicious. To remove them – click on the trash can icon next to each extension.

Once you open your IE browser, click on the Tools button at the top-right corner of the program and from the drop-down menu select Manage Add-ons. Check each one of the four different groups of add-ons and search for anything that seems undesirable. If you find anything, click on it and them select Remove.


Open the main menu of Microsoft Edge and go to Extensions. Find the extensions that you believe could be unwanted and right-click on them. Then, select Uninstall.

Step 6: Checking the Registry Editor

Open the Run search bar again and type regedit in it. Hit Enter and once the Registry Editor opens press Ctrl + F. In the search field type Penint and click on Find Next. Tell us in the comments if any results came up when you searched for Penint in your PC’s Registry.

Step 7: Deleting recent entries

For this step, you will have to open your Start Menu and copy-paste the following lines, one by one:

  • %AppData%
  • %LocalAppData%
  • %ProgramData%
  • %WinDir%
  • %Temp%

Hit Enter after each one to open a file directory. In the directories, delete the most recent entries that you find there. In the Temp folder, delete all files.

Step 8: System Restore

In order to be fully sure that the unwanted software has been removed from your machine, you can also try using a Restore Point to roll back your system its last stable configuration. However, in order to do that, you would have to previously had had a restore point created. On most systems, such points get created automatically but this isn’t always the case.
