What is "Windows Defender Browser Protection"?
"Windows Defender Browser Protection" is a technical support scam. This scam model operates by warning of potential/detected infections and urging users to contact a 'legitimate' support service. The "Windows Defender Browser Protection" scheme is run on various deceptive websites.
It claims that the browser has been compromised and immediate actions are necessary.
Note that no site can detect the presence of infections on systems, and therefore any that make such statements are undoubtedly scams. Visitors to these deceptive web pages rarely access them intentionally - they are usually redirected by intrusive advertisements or Potentially Unwanted Applications (PUAs) already infiltrated into the device.
The scam informs users that the "Windows" security system has detected attempts to stealthily exfiltrate data from their browsers. The targeted information included financial data, such as banking account credentials and associated details.
This supposed data theft has been prevented, however, it is recommended that users block all related accounts and take other unspecified security measures. It is also added that despite the success of the prevention measures, it is unclear whether other private information has been compromised and/or is still at risk.
Furthermore, this alleged virus may have damaged the system and it is thus necessary to check its health and stability. Therefore, the scam states that users must contact "Microsoft service center support" and provides the relevant telephone numbers for this purpose.
The risk of calling fraudulent technical support lines is that they are typically very expensive (despite often being indicated as "free"). These scammers cannot actually provide 'tech support', since all information presented by the respective scams is false.
Additionally, under the guise of genuine technicians, the cyber criminals may ask to run checks and/or fix the issues manually, hence gaining access to the system. To summarize, trusting "Windows Defender Browser Protection" and other similar schemes can lead to various infiltration and infections, financial loss, serious privacy issues and even identity theft.
Deceptive web pages can sometimes execute scripts to prevent users from closing them. In these cases, Task Manger must be used to end the browser process. Note that the next time the browser is opened, it is important not to restore the previous session, as doing so will reopen the malicious site.
As mentioned in the introduction, deceptive/scam web pages are commonly force-opened by PUAs. These applications can also open sale-oriented, rogue, untrusted, compromised and malicious pages. As well as causing redirects, unwanted apps also have various other capabilities.
They can function as adware - i.e., deliver intrusive advertisements (e.g. banners, pop-ups, surveys, coupons, etc.). Other PUAs classified as browser hijackers can modify browser settings, restrict/deny access to them and promote fake search engines. Regardless of their specific capabilities, most PUAs track data.
They can monitor browsing activity (URLs visited, search queries typed, etc.) and gather personal information (IP address, geolocations and other details).
This private data is often shared with third parties (potentially, cyber criminals) seeking to generate revenue. Therefore, the presence of PUAs on systems can endanger device integrity and user safety. You are strongly advised to remove all dubious applications and/or browser extensions/plug-ins immediately upon detection.

"VIRAL ALARM OF MICROSOFT", "Windows is not activated" and "CRITICAL_PROCESS_DIED" are examples of other technical support scams, however, there are many other popular models, such as alerts of outdated and/or missing software, prize giveaways, 'amazing' offers, etc.
Social engineering and scare tactics are used to further these schemes. The purpose might be to trick users into: calling expensive numbers; downloading/installing and/or purchasing nonoperational, untrusted or malicious content; revealing personal information (e.g. identity, banking, credit card details, etc.); making monetary transactions, various fees/payments, and so on.
How did potentially unwanted applications install on my computer?
PUAs proliferate via the download/installation set-ups of other programs. This deceptive marketing tactic of pre-packing normal content with unwanted or malicious software is called 'bundling'. Rushing download/installation processes (e.g. skipping steps and sections, etc.) increases the risk of unintentionally allowing bundled applications onto the system.
Certain PUAs have "official" promotional sites, from which they can be downloaded. Intrusive ads also proliferate these apps. When an intrusive advertisement is clicked, it can execute scripts to download/install PUAs without users' permission.
How to avoid installation of potentially unwanted applications
Research all content prior to download/installation. Use only official and verified download channels. P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), free file-hosting websites and other third party downloaders are untrustworthy and should be avoided.
When downloading/installing, it is important to read the terms, study all possible options, use the "Custom/Advanced" settings and opt-out of supplementary apps, tools, features and so on. Intrusive may seem legitimate, however, they cause redirects to dubious web pages (e.g. gambling, pornography, adult-dating, etc.).
If you encounter these advertisements/redirects, inspect the device and remove all suspicious applications and/or browser extensions/plug-ins immediately. If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.
