What is Cydoor Spyware?

"Cydoor Spyware" is another fake error displayed by a malicious website. Research shows that users are often redirected to this site by various potentially unwanted programs (PUPs) that infiltrate systems without permission. In addition to redirects, PUPs deliver various intrusive advertisements (coupons, pop-ups, banners, etc.), reduce overall system performance, and continually gather sensitive data.

This error states that a security breach has been detected and, for this reason, personal details (logins/passwords, banking information, etc.) are at risk. Users are encouraged to immediately resolve this issue by contacting certified Microsoft technicians (via toll-free telephone number ["1-300-190-430"] provided) and following further instructions. Note, however, that "Cydoor Spyware" is a scam - it is fake and has nothing to do with Microsoft. Cyber criminals claim to be certified technicians and generate revenue by scaring unsuspecting users and tricking them into paying for technical support that is not needed - all claims regarding security breaches are false. Furthermore, criminals often demand remote access to users' computers to install malware and/or change system settings. Criminals then claim to "detect" more issues and offer services for an additional fee. For these reasons, we strongly advise you to ignore "Cydoor Spyware" and never call the telephone number. You can remove this error simply by closing the web browser (preferably, via Task Manager) or rebooting the system, however, never re-open closed tabs after re-running the browser, otherwise you risk visiting the malicious website again.

As mentioned above, PUPs often deliver various advertisements. To achieve this, developers employ various tools (e.g., a "virtual layer") that enables placement of third party graphical content on any site. Therefore, delivered ads are likely to conceal underlying content. In addition, some ads lead to malicious websites and, in some cases, execute scripts that download/install malware. Clicking these ads thus risks various computer infections. Potentially unwanted programs often mine cryptocurrency or run other unwanted processes in the background, without users' consent. In most cases, these programs misuse available resources (RAM, CPU, etc.), thereby significantly diminishing overall computer performance. For these reasons, potentially unwanted programs should be uninstalled immediately.

"Cydoor Spyware" is virtually identical to Internet Security Alert, TEST, Cyber Security, Your TCP Connection Was Blocked, and many others. Note that all claims that the system is damaged (e.g., infected, missing files, etc.), however, these errors are designed only to to extort money from unsuspecting users. All potentially unwanted programs are very similar - they claim to enable certain "useful functions", however, these fake promises are merely attempts to give the impression of legitimacy. In fact, PUPs are designed only to generate revenue for the developers. Rather than delivering any real value for regular users, PUPs pose a direct threat to privacy and Internet browsing safety.

How did potentially unwanted programs install on my computer?

In most cases, potentially unwanted programs are distributed using a deceptive marketing method called "bundling", and intrusive online advertisements. Therefore, users often install PUPs inadvertently, without their consent. "Bundling" is stealth installation of third party applications together with regular software/apps. Developers do not adequately disclose these installations - they hide all "bundled" apps within the "Custom/Advanced" settings or other sections of the download/installation processes. Therefore, skipping download/installation steps (and clicking various advertisements) often leads to inadvertent installation of potentially unwanted programs.

How to avoid installation of potentially unwanted applications?

The main reasons for computer infections are poor knowledge and careless behavior. Therefore, be very cautious when downloading/installing software and browsing the Internet. Carefully analyze each window of the download/installation windows and opt-out of all additionally-included programs. Bear in mind that intrusive ads usually look legitimate, however, they are distinguishable for their redirects - most lead to survey, gambling, adult dating, pornography, and other suspicious sites. If you encounter such redirects, immediately eliminate all dubious applications/browser plug-ins. The key to computer safety is caution.
