Expanded Service

The Expanded Service Malware will redirect your browser when you try to use it.

Some of the most annoying pieces of software you could encounter on your PC are none other than the infamous browser hijackers. An application of this category can latch onto pretty much any browsing program an user can have on their computer. This includes, but is not limited to, browsers such as Safari, Chrome, Firefox, Opera, Vivaldi, Brave and so on. Once the unpleasant software piece has gotten installed onto the computer and has entered the browser, it is typical for it to start imposing changes on the browser without needing the Administrator’s permission. The most common changes a hijacker can impose are a replacement of the toolbar, of the search engine tool and of the homepage and the new-tab page. Another highly irritating and quite problematic trait of hijackers is the fact that they can spam the user’s screen with random page-redirects, banners, pop-ups, blinking boxes and other types of adverts. Normally, the ads won’t stop no matter what you do if the hijacker is still functional inside the PC. This is why, if you have one such piece of software inside your computer system, the most advisable course of action you could take is to find the unwanted software on the computer and remove it with all of its data. This, however, might be easier said than done. A hijacker app is not like a regular program that you could simply uninstall from your Control Panel and it is not like any other browser extension that you could simply disable from the Add-ons manager. In most instances, the presence of such an app on your PC would require specialized help if you are to remove the unpleasant software element from your computer and browser.

The Expandedservice App

Expanded Service is categorized as a browser hijacker by security experts. Expanded Service is known to cause browser redirects and different pop-up advertisements in addition to security vulnerabilities.

Despite not being as threatening and as dangerous as viruses of the Ransomware, of the Trojan Horse or of any other similar malware category, browser hijackers are still oftentimes seen as security threats. It is,however, important to know exactly what about the hijackers really is threatening. On their own, apps like Expanded Service, Bing Redirect or Resources Source wouldn’t typically go out of their way to cause any damage or corruption to your PC and/or to your files. The representatives of this software category are mostly used for advertising and not for casing any real harm. Therefore, if you currently have Expanded Service on your PC, there really is no need to get panicked as this app will most likely not harm your computer in any way. However, the security issue with hijackers comes from their ads and page redirects. You see, you can never be hundred percent sure that the ads generated on your screen are safe and aren’t actually disguised links that can land you on some nasty and illegal sites and pages that hackers use to spread Ransomware, Trojan Horses, Spyware, Rootkits and other similar types of malware. The malvertising method is indeed one of the most commonly employed techniques for spreading malicious software which is why it is generally not a good idea to allow some obscure app that tends to generate a lot of online ads stay on your computer for any extended period of time.

What is Expanded Service?

Expanded Service is regarded as a type of a browser hijacker. Threats like Expanded Service are known to cause different problems like changing of the user’s designated home page or even the preferred browser of choice.

Though a big number of software components of the hijacker category have their official sites whence one could download them, the most popular ways of distributing such apps are actually ones that allow them to enter the system without the user’s knowledge (yet, with their uninformed permission). Such methods include but aren’t limited to malvertising, the use of spam letters, the use of low-quality downloads and misleading online offers and so on. In some cases, a hijacker could even get bundled with a legitimate program and get installed alongside it if the user doesn’t pay attention to the setup settings and forgets to uncheck the hijacker from the installation menu. That’s why you must always be careful and vigilant when installing new software on your PC – always uncheck any optional components if you don’t think you can trust them.

Expanded Service Malware 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.
