Removal instructions for apps designed to promote pages like Trojan Spyware Alert scam
What is Trojan Spyware Alert scam?
Scammers behind this tech support scam attempt to trick unsuspecting visitors into believing that a computer is infected with some Trojan and/or Spyware and calling the provided number. In most cases users who contact scammers behind websites like this one are encouraged to pay for unnecessary services and/or software, or even provide a remote access to the computer. In one way or another, websites of this kind must be ignored. This particular page is hosted using the Amazon AWS - a legitimate service provided by Amazon. It is not the first case when cyber criminals/scammers employ this service for malicious purposes.
Like most tech support scam pages this one is designed to look like an official Microsoft website. Although, the actual Microsoft company has nothing to do neither with this or any other website of this kind. This particular page displays two deceptive pop-up windows notifying visitors that it has detected "Trojan Spyware", found the error code "#0x898778" and blocked the access to a computer for security reasons. Also, this page claims that data such as email credentials, banking passwords, Facebook login credentials, pictures and documents have been compromised as well. Visitors are instructed to solve the occurred problem with the help of "Windows Support" by calling the +1-(877)-570-9733 number as soon as possible. In most cases scammers behind such pages attempt to trick users into paying money for supposedly legitimate technical support services, software or allowing them to access and control a computer remotely via some Remote Access/Administration Tool (RAT). It is worthwhile to mention that by having such access cyber criminals/scammers could infect a computer with some malware (e.g., ransomware, Trojan-type malware), steal personal information or perform other malicious actions.

A couple of examples of other similar scams are "ERROR # 0x6a4-0xf9fx3999", "Activation Failed! (Error Code 001)" and "Windows Error Code: DLL011150". To sum up, in most cases scammers behind such pages attempt to trick visitors into believing that there is something wrong with their computers and calling a certain number. Once called, scammers try to extract some money from callers or attempt to trick them into installing some RAT. it is worthwhile to mention that most users do not visit websites of this kind on purpose - such pages get opened through other untrustworthy sites, deceptive ads or by installed potentially unwanted applications (PUAs).
How did potentially unwanted applications install on my computer?
One of the most commonly used ways to distribute/promote PUAs is to integrate them in download and/or installation setups of other programs as additional offers. This distribution method is known as "bundling". Users download and/or install PUAs together with other programs when they leave settings like "Advanced", "Custom" of their setups unchanged (or available checkboxes unticked). Simply said, when users do not decline offers to download and/or install unwanted apps. Also, in some cases users cause unwanted downloads and/or installations by clicking deceptive advertisements that are designed to execute certain scripts.
How to avoid installation of potentially unwanted applications?
It is not recommended to download software, files from unofficial websites, through Peer-to-Peer networks (like torrent clients, eMule), third party downloaders, etc., or install software with third party installers. Files and programs should be downloaded only from official websites and via direct links. Another way to prevent unwanted downloads and/or installations is to check downloaders and/or installers for "Custom", "Advanced" or other settings and see if they mention offers to download and/or install unwanted apps. Intrusive advertisements that appear on various questionable pages should not be clicked as well - quite often such ads are designed to promote other untrustworthy websites or even cause downloads and/or installations of unwanted apps. Any unwanted, suspicious extensions, add-ons and plug-ins that are installed on a browser should be removed. The same applies to programs of this kind that are installed on the operating system/computer. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
