What is "!!Rootkit!! Malware Detected"?

During our investigation of suspicious websites and associated advertisements, we came across a technical support scam site that displays a deceitful pop-up message falsely indicating that the Windows operating system is infected. Such pages are usually created with malicious intentions, aiming to acquire personal information, solicit funds, or promote potentially harmful software.

"!!Rootkit!! Malware Detected" scam in detail

One of the pop-ups displayed by this deceptive site claims that the Windows key on the user's machine is pirated. It further alleges that the computer has been infected with a Rootkit Malware that has compromised various data, including financial details, email logins, social networking information, pictures, and documents.

The warning asserts that immediate action is necessary to prevent the theft of passwords, financial login details, personal files, and pictures or documents. It urges the user to contact Microsoft Helpline urgently to receive assistance from their engineers for the removal process over the phone.

Another fake message states that access to the user's PC has been disabled for security reasons. It prompts the user to call the Microsoft Helpline at a specific phone number, +1-833-784-7223.

This is one of the technical support scams where scammers impersonate legitimate technical support representatives or companies to deceive unsuspecting individuals. Typically, these scams involve unsolicited phone calls, fake pop-up messages, or misleading websites.

The scammers often employ scare tactics, such as claiming that the victim's computer is infected with malware or facing critical issues. They aim to trick victims into providing personal information, granting remote access to their devices, or making payments for unnecessary services or software.

Two notable examples of scams utilized to deceive users into installing remote administration tools are the UltraViewer scam and the TeamViewer scam. With remote access to computers, scammers can engage in various malicious activities. They can potentially steal sensitive personal information, such as login credentials, financial data, or personal files.

Additionally, scammers can exploit the remote access to execute unauthorized actions on the compromised computer, including installing malware, hijacking the system for illegal activities, or using it as a launching pad for further attacks on other devices or networks.

Similar scams in general

Typically, such scams employ social engineering techniques to create a sense of urgency or fear in the victim, compelling them to take immediate action. Scammers commonly impersonate well-known technology companies or trusted technical support representatives to gain the victim's trust. More often than not, technical support scams involve fake phone numbers.

Examples of similar scams are "Your version of Windows is out of date", "Threats Detected:Stuxnet", and "Windows Key Code Is Not Valid And Seems Pirated".

How did I open a scam website

Users may encounter scam pages through various channels. One common avenue is encountering malicious advertisements or pop-ups that redirect users to fraudulent websites displaying scam messages. These deceptive ads and pop-ups can appear on legitimate websites or result from adware installed on the user's device.

Also, users may end up on scam pages while visiting torrent sites, illegal movie streaming sites, and similar pages that use rogue advertising networks. Another method involves receiving phishing emails that contain links leading to deceptive (fake) pages.

These emails often masquerade as legitimate sources, such as well-known tech companies or trusted online retailers, and employ social engineering tactics to convince users to click the provided links.

How to avoid visiting scam pages?

Exercise caution when clicking on links, especially those received through unsolicited emails, social media messages, or unfamiliar websites. Avoid interacting with pop-up ads that appear unexpectedly. Utilize reputable antivirus and anti-malware software on your device and keep it up to date.

Download apps and files from trustworthy sources such as official pages and stores. Do not agree to receive notifications from suspicious websites. If your computer is already infected with unwanted apps, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
