This page aims to help you remove “Windows Warning Alert Malicious Spyware/Riskware Detected”. Our removal instructions work for Chrome, Firefox and Internet Explorer, as well as every version of Windows.

Most users who encounter apps like “Windows Warning Alert Malicious Spyware/Riskware Detected” would typically want to remove them from their machines and understandably so. “Windows Warning Alert Malicious Spyware/Riskware Detected” and other similar pieces of software are all applications that belong to the so-called browser hijacker software group. A browser hijacker application is a software component that oftentimes resembles an extension for a browser such as Chrome, Firefox, Edge, IE or any other. At first, you might not notice anything sketchy or undesirable about “Windows Warning Alert Malicious Spyware/Riskware Detected”. However, once the unpleasant app starts operating from within your browser, you’d quickly realize why one would want to have such a software piece removed from their computer system. This hijacker, similarly to the rest of its type, is likely to spam your screen with various unpleasant adverts, page redirects and banners as well as add a new toolbar, a new search engine and a new homepage to the browser which would, of course, replace the old one that you have been using up to that point. Some users might not see this as a particularly big issue. After all, you could still use your browser and it’s not like there’s some kind of nasty malware virus like a Ransomware or a Trojan Horse on the computer. Sure, this is one way of seeing things. However, if you are like most people, you’re likely to get really irritated by the sudden (and unauthorized) changes imposed on your browser. Also, the nagging ads, pop-ups, banners, page-redirects and box messages are yet another particularly annoying effect that a hijacker app the likes of “Windows Warning Alert Malicious Spyware/Riskware Detected” could have on your browser. In most cases, the nagging advertising materials won’t go away no matter what you do if the hijacker remains on your computer. You might try to manually close the ads by clicking on their X button (provided that they have one) only to get redirected to some obscure and unknown page that the hijacker is trying to push and promote. Also, even if you manage to close a certain advert, it is more than likely that a new one would appear in its place right away.

Ways hijacker apps get distributed

If you have had “Windows Warning Alert Malicious Spyware/Riskware Detected” installed on your PC but you have no idea how that has happened, know that you are likely not the only person in such a situation. Hijacker apps typically use sneaky methods of distribution and installation that allow them to get onto as many computers as possible. It is important for the creators of hijacker apps to get their products installed on many machines as this directly correlates to the income a hijacker’s developers could earn from the ads that the pesky application generates.

Some of the more popular methods for spreading such apps are spam messages, malvertising, the use of torrents and sketchy streaming sites, etc. The file-bundling method where the hijacker is put inside an installation package for another program is also very popular. Make sure that you always take a careful look at all the settings available in the setup managers for new programs you want to install and uncheck the optional components that you might not want to have installed on your PC so as to avoid future hijacker encounters.
