"Windows Antivirus - Critical Alert" removal instructions
What is "Windows Antivirus - Critical Alert"?
"Windows Antivirus - Critical Alert" is categorized as tech-support scam. Scams of this type attempt to trick people into believing that their computers and personal details are at risk, and they encourage them to call the telephone number provided. Typically, scammers promote these so-called 'services' through various untrustworthy web pages, which are often opened by potentially unwanted applications (PUAs) installed on the browser or operating system. If this scam is opened through your browser, we recommend that you ignore it and check for PUAs that might be causing the problem.
The "Windows Antivirus - Critical Alert" scam runs a fake scan and inform users that their data is at high risk. According to this web page, someone is trying to steal banking information, credit card details, and credentials of other accounts. To avoid problems, visitors are encouraged to call the "+1 (888) 982-8105" telephone number, which will supposedly allow them to contact someone from Microsoft. In fact, calling this number leads to contacting the scammers who designed this tech-support scam. Additionally, this page displays a pop-up window stating that another page, which was apparently visited earlier, was infected and placed the computer at risk. It also encourages users to call the telephone number. Furthermore, this page starts a countdown timer that, once expired, supposedly starts a "Hard Drive safety delete". In summary, this scam tricks people into calling scammers immediately and into believing that they will lose their data and have their personal details stolen unless they take action within five minutes of the page being opened. The information on these pages should never be trusted. If a browser opens a page of this type, ignore the information and close it. Note, however, that some scam sites prevent visitors from closing them. In these cases, they can be closed by ending the browser process via Task Manager. Note also that restoring the previously closed session will return you to the scam page (so do NOT restore the closed browsing session). If the browser opens the "Windows Antivirus - Critical Alert" scam in a full-screen mode, it can be closed by pressing the "Esc" key.
There are many cases whereby web pages of this type are opened by PUAs. If installed, PUAs also collect browsing data and feed users with unwanted ads. They record details such as users' IP addresses, geolocations, URLs of visited websites, entered search queries, and other similar data. Developers share the data with other parties (potentially, cyber criminals) who misuse it to generate revenue. Having PUAs installed can thus lead to problems with privacy, browsing safety, etc. Additionally, apps of this type often serve intrusive ads such as coupons, banners, pop-ups, surveys and so on. Typically, people who click the ads are redirected to untrustworthy web pages, or they cause download and installation of other unwanted applications.

There are many pages that are designed by scammers. Some examples include "Hard Drive Safety Delete", "Virus Support Alert", and "Windows Is Not Activated". They commonly display "tech-support" numbers that, if called, connect people with scammers. Their main goal is to extort money from people by selling unnecessary software or tricking them into paying for online 'technical support'. None of these pages are official or can be trusted. PUAs that open pages of this type are usually disguised as legitimate, useful tools, however, they simply cause problems by opening dubious web pages, collecting data, and displaying ads.
How did potentially unwanted applications install on my computer?
Unwanted downloads/installations usually occur when people click intrusive ads or when they download and install (usually free) software without paying attention to the setup details. When clicked, many deceptive ads run scripts that download and install PUAs or even malware. In other cases, PUAs are installed when developers use the "bundling" method to trick them. They bundle (include) PUAs in the set-ups of other software, however, this information is usually hidden in options such as "Custom", "Advanced", and other similar parts. By leaving these settings unchecked and unchanged, many people allow PUAs to be downloaded and installed with other, regular software.
How to avoid installation of potentially unwanted applications?
Download software from official and trustworthy websites. Do not trust other sources such as third party downloaders, torrent clients, eMule (and other Peer-to-Peer networks), unofficial websites, or tools such as third party installers. All downloads and installations should be performed correctly: check all available "Custom", "Advanced", and other similar parts and deselect any bundled PUAs. Do not trust intrusive ads, especially if they are displayed on dubious websites. These often redirect to potentially malicious pages or cause unwanted downloads or installations. If a browser causes unwanted redirects or displays intrusive ads regularly, it is possible that this is due to a PUA (extension, plug-in, or add-on) installed on the default browser. All unwanted, unknown browser apps should be uninstalled immediately. You are also advised to remove suspicious, unwanted programs installed on the operating system. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
