Removal instructions for apps designed to promote the Trojan Spyware Alert scam and similar web pages

What is the Trojan Spyware Alert scam?

Scammers behind this tech support scam attempt to trick unsuspecting visitors into believing that their computers are infected with a Trojan and/or Spyware and calling the provided number. In most cases, users who contact scammers behind these sites are encouraged to pay for unnecessary services and/or software, or even to provide remote access to their computers. You should avoid these websites. This particular web page is hosted using Amazon AWS, a legitimate service provided by Amazon. This is not the first case whereby cyber criminals/scammers have employed this service for malicious purposes.

Trojan Spyware Alert scam

Like many tech support scam web pages, this one looks very similar to the official Microsoft website. In fact, Microsoft has nothing to do with this or other websites of this kind. This particular page displays two deceptive pop-up windows notifying visitors that it has detected "Trojan Spyware", found error code "#0x898778", and blocked access to the computer for security reasons. This page also claims that data such as email credentials, banking passwords, Facebook login credentials, pictures and documents have been compromised. Visitors are instructed to resolve the problem with the help of "Windows Support" by calling the +1-(877)-570-9733 number immediately. In most cases, scammers behind such pages attempt to trick users into paying for supposedly legitimate technical support services and software, or allowing them to access and control their computers remotely via a Remote Access/Administration Tool (RAT). Note that granting such access to cyber criminals/scammers could infect your computer with malware (e.g., ransomware, Trojan-type malware), and they might steal personal information or perform other malicious actions.

Some examples of other similar scams are "ERROR # 0x6a4-0xf9fx3999", "Activation Failed! (Error Code 001)" and "Windows Error Code: DLL011150". Scammers behind these pages attempt to trick visitors into believing that there is a issue with their computers and into calling a specific number. Once the call is made, scammers try to extort money from people or attempt to trick them into installing a RAT. Most users do not visit these sites intentionally - they are opened through other untrusted sites, deceptive ads, or by installed potentially unwanted applications (PUAs).

How did potentially unwanted applications install on my computer?

Browser hijackers, adware-type apps, and other types of PUAs are commonly distributed by integrating them into the download and/or installation set-ups of other programs, so that a proportion of users inadvertently download and install them together with their chosen software. This distribution method is known as "bundling". Offers to download and install additionally-included apps usually appear in "Advanced", "Custom" and other settings of the set-ups (where they can usually be declined). Many users fail to check and change these settings, thereby granting permission for PUAs to be downloaded and installed by default. In addition, unwanted downloads and installations are sometimes caused by clicking deceptive advertisements capable of executing certain scripts.

How to avoid installation of potentially unwanted applications

Download software and files from official websites and via direct links. It is not safe to use torrent clients, eMule (or other Peer-to-Peer networks), third party downloaders, unofficial websites or other sources of this kind. Avoid third party installers. Check "Advanced", "Custom" and other settings, and decline offers to download or install unwanted software. Do not click ads that are displayed on dubious websites, since they can open other untrusted websites or even cause unwanted downloads and installations. Remove any unwanted, suspicious applications (extensions, add-ons, and plug-ins) that are installed on the browser. The same should be applied to programs of this kind that are installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

Note that the safest source for downloading free software is via developers' websites only. To avoid installation of adware, be very attentive when downloading and installing free software.
