Jirin Adware 1024x633

If you are struggling with an endless stream of obstructive and interrupting pop-ups, ads, banners and page redirects that show on your screen during your browsing sessions and if your main browser seems to have gotten modified in some ways (replaced search engine tool, homepage, new-tab page and so on) without your approval, then you most likely have what is called a browser hijacker on your computer and in your browser(s). A browser hijacker is not something to be too worried about as most apps of this category are not dangerous and are certainly much less problematic than a Ransomware or a Trojan horse virus.

However, you can still get plenty irritated by a hijacker and there could still be some security issues if such an app has managed to latch onto your Safari, Chrome, Firefox or to any other browser that you primarily use. Here, it should be noted that though sometimes switching to another browser might temporarily deal with the hijacker issue, it is not the best way to take care of the intrusiveness. After all, there’s a reason you have chosen to use your current browser and not some other so you’d probably want to continue using it like before instead of switching to another one. Also, some hijackers might be able to affect all your browsers at once which means that the only surefire way of overcoming the hijacker-related predicament would be to get rid of the rather unpleasant piece of software.

Jirin for Mac

Jirin for Mac is aggressive and potentially unsafe site-promoting software that gets installed in Mac browsers. The main purpose of Jirin for Mac and other apps of its type is to gain more views for the sites that sponsor their creators.

Jirin, as you might already know, is a browser hijacker-like piece of software that, too, seems to possess a number of abilities that most users find rather intrusive and frustrating. This app could, just like most other hijackers, might try to impose a number of changes to your browser under the pretense that this would make your browsing program more useful and effective when in reality the main reason for the changes is to facilitate the advertising activities that the unwanted is supposed to push. Again, there will likely be many ads, redirects to unknown sites and pages, banners, pop-up messages, blinking boxes and all other kinds of obnoxious and highly irritating advertising materials. In case you are currently going through this, we can offer you to use the following guide and/or the professional anti-malware removal tool available in it in order to eradicate the unwanted software.

As you can tell, fully removing a hijacker app like Jirin in a way that would not allow it to come back to bother you requires quite more than simply uninstalling the pesky software component in the way you’d uninstall any other program. Still, even a non-experienced user should be able to take care of this undesirable software piece as long as they closely follow the instructions posted in our removal guide or use the anti-malware tool recommended in it.

What is Jirin?

Jirin is an unwanted app of the browser hijacker variety that will change the starting page of your Mac browser. Jirin will also try to learn what sites and online content you are interested in so that it could later show you ads that match your supposed preferences.

Now, something we should tell you here is the fact that even if Jirin isn’t a nasty Ransomware virus and even if it can’t harm your computer and mess with your data and virtual privacy like a Trojan Horse program could, it’s still a software component that might lead to the exposure of your system to potential danger (especially if you are not cautious and vigilant. As you probably already know, online ads are oftentimes not what they seem – they might offer you something really tempting and attractive and once you click on them redirect you to some shady and obscure webpage. This is why it’s important that you generally keep away from any advertisements if they look unreliable. However, if there’s a hijacker in your browser, it might be rather hard to avoid all the advertising materials streamed to your browsing program. That’s why you must eliminate the software responsible for the endless generation of ads that you’ve been subjected to which, in this case, would be Jirin.

The Jirin app

The Jirin app is a type of site-promoting software that will flood your browser with ads and sudden page redirects. The Jirin app can get installed in any Mac-compatible browser and it normally gets distributed alongside other low-quality software products, forming software bundles with them.

Some of the more obvious sources of unwanted and unreliable software in general are the spam messages and e-mails, the obscure ads and too-good-to-be-true offers you might see inside questionable sites, the pirated programs that many users download as well as a lot of borderline illegal (or outright illegal) video streaming sites. Naturally, you are supposed to avoid those if you want to keep your computer as safe as possible. However, a hijacker can come to you as a bundled component to a legitimate program since hijacker apps are not generally regarded as illegal and could get distribute in alongside regular software. So, if you want to install a new program on your computer, you should always first have a close look at the details in its setup manager – see if there are any optional clauses and added bonus components. There could be an optional clause that would allow the installer to change your homepage or search engine or to add some component to your browser. If you see anything like that and don’t like it, do not hesitate to uncheck it before you continue.

Remove Jirin from Mac

For a quick way to remove Jirin try to do this inside your Mac browser:

  1. Open your Mac browser.
  2. Go to Preferences.
  3. Now navigate to the extensions sub-menu.
  4. Look for any unfamiliar entries, including Jirin.
  5. Remove Jirin from your Mac as well as any other suspicious-looking items by clicking on the trash bin icon.

If this does not help then continue reading this article for more detailed instructions on how to get rid of Jirin!

Step1

The first thing you need to do is to Quit Safari (if it is opened). If you have trouble closing it normally, you may need to Force Quit Safari:

You can choose the Apple menu and click on Force Quit.

Alternatively, you can simultaneously press (the Command key situated next to the space bar), Option (the key right next to it) and Escape (the key located at the upper left corner of your keyboard).

If you have done it right a dialog box titled Force Quit Applications will open up.

In this new dialog window select Safari, then press the Force Quit button, then confirm with Force Quit again.

Close the dialog box/window.

Step2

WARNING! READ CAREFULLY BEFORE PROCEEDING!

Start Activity Monitor by opening up Finder, then proceed to activity-monitor

Once there, look at all the processes: if you believe any of them are hijacking your results, or are part of the problem, highlight the process with your mouse, then click the “i” button at the top. This will open up the following box:

chromeinfo

Now click on Sample at the bottom:

chromesample

Do this for all processes you believe are part of the threat, and run any suspicious files in our online virus scanner, then delete the malicious files:

    Step3

    The next step is to safely launch Safari again. Press and hold the Shift key while relaunching Safari. This will prevent Safari’s previously opened pages from loading again. Once Safari is opened up, you can release the Shift key.

    On the off chance that you are still having trouble with scripts interrupting the closing of unwanted pages in Safari, you may need to take some additional measures.

    First, Force Quit Safari again.

    Now if you are using a Wi-Fi connection turn it off by selecting Wi-Fi off in you Mac’s Menu. If you are using a cable internet (Ethernet connection), disconnect the Ethernet cable.

    Step4

    Re-Launch Safari but don’t forget to press and hold the Shift button while doing it, so no previous pages can be opened up. Now, Click on Preferences in the Safari menu,

    Preferences in Safari

    and then again on the Extensions tab,

    extensions in safari

    Select and Uninstall any extensions that you don’t recognize by clicking on the Uninstall button. If you are not sure and don’t want to take any risks you can safely uninstall all extensions, none are required for normal system operation.
    Step5

    The threat has likely infected all of your browsers. The instructions below need to be applied for all browsers you are using.

    Again select Preferences in the Safari Menu, but this time click on the Privacy tab,
    Privacy in Safari

    Now click on Remove All Website Data, confirm with Remove Now. Keep in mind that after you do this all stored website data will be deleted. You will need to sign-in again for all websites that require any form of authentication.

    Still in the Preferences menu, hit the General tab

    General Tab in Safari

    Check if your Homepage is the one you have selected, if not change it to whatever you prefer.
    Default Home Page

    Select the History menu this time, and click on Clear History. This way you will prevent accidentally opening a problematic web page again.
