What is Windows Malware Detected?

"Windows Malware Detected" is another fake error displayed by deceptive websites. Research shows that many users visit these sites inadvertently - they are redirected by potentially unwanted programs (PUPs) or other malicious sites. PUPs typically infiltrate systems without permission, deliver intrusive advertisements, and continually record sensitive data.

Windows Malware Detected scam

This error states that the system has been infected with a certain type of malware that performs suspicious actions. It is also stated that personal details (e.g., logins/passwords) and stored data are at risk. Therefore, users are encouraged to immediately contact "tech support" via a toll-free telephone number ("1-855-341-4034") provided. Be aware, however, that the "Windows Malware Detected" error is fake and a scam. Cyber criminals (developers) generate revenue by tricking users into calling and paying for tech support that is not required. In this way, they abuse users' trust. Therefore, ignore "Windows Malware Detected". This pop-up error asks users to enter an administrator login and password, however, do not do this - the information will probably be saved and misused. The "Windows Malware Detected" error can be removed simply by closing the web browser, however, some rogue sites employ scripts that prevent users from closing browsing tabs/windows. In these cases, end the browser process using Task Manager or simply reboot the system. After re-running the browsers, do not restore the previous session, otherwise you will end up visiting the malicious sites again.

Potentially unwanted programs deliver various intrusive advertisements such as coupons, banners, pop-ups, etc. To achieve this, developers employ tools that enable placement of third party graphical content on any visited website. Therefore, delivered ads often conceal underlying content, thereby significantly diminishing the browsing experience. Furthermore, these advertisements redirect to malicious websites and even execute scripts designed to download and install PUPs (or even malware). Therefore, even a single accidental click can result in high-risk computer infections. PUPs gather various information relating to web browsing activity. Collected data (IP addresses, URLs visited, pages viewed, queries entered into search engines, keystrokes, etc.) usually includes personal details that developers share with third parties (potentially, cyber criminals). These people misuse private data to generate revenue. The presence of data-tracking apps can lead to serious privacy issues or even identity theft, and thus all should be uninstalled immediately.

"Windows Malware Detected" shares many similarities with dozens of other fake errors such as Google Chrome Support Centre, Computer Detected To Be Corrupted, and COMPUTER BLOCKED. All falsely claim that the system is damaged (e.g., infected, missing files or similar). The only purpose of these errors is to extort money from unsuspecting users. Potentially unwanted programs also share many similarities. By offering "useful features", they attempt to give the impression of legitimacy, however, rather than giving any real value for regular users, PUPs pose a direct threat to their privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

As mentioned above, Windows Malware Detected often infiltrates systems without permission. This is due to the lack of knowledge and careless behavior of many users. Potentially unwanted programs are typically distributed using intrusive advertising and "bundling" (stealth installation of PUPs with regular software) methods. Developers do not disclose PUP installations properly. Therefore, all are hidden within "Custom/Advanced" settings (or other sections) of the download/installation processes. Clicking advertisements and skipping download/installation steps often leads to inadvertent installation of rogue programs. In this way, users expose their systems to risk of various infections and compromise their privacy.

How to avoid installation of potentially unwanted applications?

The key to computer safety is caution. Therefore, to prevent system infiltration by PUPs, be very careful when browsing the Internet and downloading/installing software. Intrusive advertisements typically seem legitimate, but once clicked, redirect to gambling, adult dating, pornography, and other dubious websites. If you experience these redirects, immediately remove all dubious applications and browser plug-ins. Furthermore, carefully analyze each step of the download/installation processes and opt-out of all additionally-included programs. We also advise you to avoid using third party downloaders/installers, since developers monetize them by promoting PUPs ("bundling" method). Software should be downloaded from official sources only, using direct download links.
