Swift Engine

Swift Engine is an unwanted program designed to hijack the settings of your Mac browser and impose some unwanted changes in it. Typically, hijackers like Swift Engine seek to redirect your traffic to promoted sites, and they change the homepage and the search engine to achieve that.

The Swift Engine Virus will interfere with your browser.

The browser hijackers are a type of unwanted software that’s known for invading the user’s browser and hijacking the browser’s settings. Certain changes are made in the browser such as a replacement of the default address used as homepage and of the browser’s search engine tool that gets used whenever the user tries to search for something on the Internet. For instance, if your search engine used to be Google, after the hijacker’s installation it has probably been replaced by some unknown to you search engine tool that doesn’t provide the same level of quality in its searching services. Oftentimes the browser hijackers also get the user page-redirected to questionable and misleading sites – gambling sites, browser game sites, or different online stores. Chrome, Firefox, Safari, and pretty much any other browser could get infected by a browser hijacker. The apps of the hijacker category are compatible with most types of browsers so it really doesn’t matter what your specific browser of choice is – if you land a hijacker on your computer it is likely that you will see its effects in the system’s main browser.

Swift Engine on Mac

Swift Engine for Mac is an intrusive browser hijacker app that replaces the main search engine of the browser and introduces some other unwanted changes to its settings. Swift Engine for Mac might land you on unsafe sites which is why you should uninstall it.

To some of you, the redirects and the modifications imposed on the browser may seem like a mere irritation that can be ignored but the truth is that the longer an app like the newly released Swift Engine hijacker is allowed to stay in the computer the greater the frustration caused by it would become. In some cases, some such programs are even known to show ads right over the main part of an online page, covering that part and forcing the user to click on the displayed ads just so that it would go away and reveal the actual contents of the page. Furthermore, some of the ads may be misleading and may try to scare you into downloading fake anti-malware programs by telling you there’s a virus in your system. Do not trust such pop-ups and fake warning messages – the only warnings you should trust are the ones coming directly from your OS or from your antivirus software. If some site or an online pop-up tells you your computer has been compromised just ignore it without touching it.

The SwiftEngine App

The Swift Engine app is a page-redirecting Mac browser extension that is categorized as a browser hijacker due to its aggressive behavior. The Swift Engine app won’t directly damage the computer it’s installed on but its ads and page-redirects may get the system infected with viruses.

Aside from the irritation and the deceitful tactics used by apps like Swift Engine, there’s actually a bigger problem related to this sort of software. That problem is the risk of getting exposed to Ransomware, Trojans, and other viruses and malware after clicking on a compromised ad. If you want to decrease the chances of getting your system exposed to Ransomware or other highly dangerous malware, it’s best if you uninstall the Swift Engine hijacker and the guide we will give you now will show you how you can remove this invasive app.

Swift Engine Virus Removal


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 ComboCleaner to see if it can detect parasite files for you.

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.



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 ComboCleaner
a professional malware removal tool.

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.


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,

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,

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.
