"ERROR 0xC004FC03" removal instructions
What is "ERROR 0xC004FC03"?
ERROR 0xC004FC03 is the name of an error, supposedly caused by a virus. This error is detected by deceptive/scam websites. It is used to scare users into calling a fraudulent Microsoft technical support line and consequently trick them into paying for fake services. There is a genuine "ERROR 0xC004FC03" error code, which is displayed when the Window OS (Operating System) fails activation; however, the warnings of it found on webpages are not related to the actual error. It must be emphasized that no site is capable of detecting issues/threats on devices; any that claim to do so cannot be trusted. Usually, such rogue websites are opened by PUAs (Potentially Unwanted Applications), already present on the device. Users should note that these applications do not need explicit permission to infiltrate systems. PUAs are designed to generate redirects to untrustworthy and malicious webpages, run intrusive advertisement campaigns and spy on users' browsing activity.
When the deceptive page is entered, it displays a pop-up window. The message in it requests visitors to provide their name and password. It also claims to have detected suspicious activity on the device, due to a virus present in the system. For further assistance, a fake Microsoft tech support number is provided. Furthermore, users are informed that their data is endangered. The reason behind the ERROR 0xC004FC03 is allegedly a virus, which is responsible for a missing system file, causing Window OS (Operating System) to fail. The pop-up continues pushing visitors into calling the "free" technical support. Users are warned not to shutdown or restart their computers, as they risk system failure and permanent data loss. The message ends with a final prompt to call the false support line, while reinforcing that the number (+1-833-292-1252) is toll free. These scams are created purely for the purpose of generating revenue for their designers, i.e. they are designed to extort money. For example, any numbers listed in such - can have high fees. Users may also be tricked into paying for some imaginary services rendered and/or pushed into purchasing illegitimate/nonfunctional or malicious software. Sometimes, rogue webpages cannot be closed in the usual way (by closing the browser tab/window), then the browser process should be terminated using the Task Manager. Before the browser is reopened, it is important not to restore the previous session, as failing to do so will reopen the scam page (or cause the site that redirected to it prior to repeat the redirect).
In general, PUAs are quite similar, some are even identical. They appear legitimate and offer various "useful" features/functions to entice users into installation. However, these features rarely work as advertised and in most cases are downright nonfunctional. These applications have many undesirable and harmful abilities. They generate redirects to sale-based, untrustworthy, compromised, deceptive/scam and even malicious websites. Some types run intrusive advertisement campaigns (pop-ups, banners, surveys, coupons, etc.), by employing a variety of tools to enable third party graphical content. The ads they deliver not only diminish browsing quality (overlay page content) but also carry certain risks themselves. Others hijack browsers and promote fake search engines. It is not uncommon for PUAs to have data tracking abilities as well. They record browsing activity (browsing and search engine histories) and gather users' personal information (IP addresses, geolocations and personal details). This sensitive data is then shared with third parties (potentially, cyber criminals), seeking to misuse it for financial gain. To summarize, unwanted apps can cause browser/system infiltrations and infections, and lead to severe privacy issues, financial losses, even identity theft. To ensure device and user safety - all dubious applications and browser extensions/plug-ins must be removed without delay.

To eliminate ERROR 0xC004FC03 virus our malware researchers recommend scanning your computer with Spyhunter.
There are many deceptive sites out there. They typically share common traits, such as using scare-tactics to promote technical support services and/or untrustworthy programs. These webpages show alerts/alarms, concerning "detected" issues/threats and offer to provide tech support and/or software, supposedly able to remove the problems. ERROR # ER36dx9832(3), Norton Subscription Has Expired Today, Windows Antivirus - Critical Alert are a few examples of scams similar to ERROR 0xC004FC03.
How did potentially unwanted applications install on my computer?
Some PUAs have "official" websites, from which they can often be downloaded for "free". These apps also proliferate via download/install setups of other programs. The false marketing technique of pre-packing ordinary software with undesirable or malicious content is called "bundling". Rushed download/installation processes (e.g. used pre-set options, skipped steps, etc.) - endanger devices with potential system infiltrations and infections. Intrusive advertisements spread PUAs as well. Once clicked, said ads can execute scripts to download/install unwanted content without user consent.
How to avoid installation of potentially unwanted applications?
It is recommended to always research products to verify their legitimacy, before downloading/installing them. Only trustworthy and verified download channels should be used. P2P sharing networks (BitTorrent, eMule, Gnutella, etc.), unofficial and free file-hosting sites, third party downloaders and similar sources are considered to be untrustworthy; therefore are advised against use. Download/Installation processes should be treated with caution. That includes reading terms, exploring all possible options, using the "Custom/Advanced" settings and declining to download/install additional apps, tools, functions, etc. Care should be exercised when browsing. Intrusive adverts usually look legitimate and harmless, however they redirect to various questionable webpages (e.g. gambling, pornography, adult-dating and others). Should users encounter ads/redirects of this kind, they are strongly advised to check the system and immediately remove all suspicious applications and/or browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Spyhunter for Windows to automatically eliminate them.
