"System Warning Alert" scam redirect removal instructions

What is the "System Warning Alert" scam?

"System Warning Alert" is a technical support scam claiming that users' devices have been infected with spyware and other viruses. This scheme urges people to immediately contact 'tech support' by calling a supposedly toll-free telephone number. Note that no web page can detect threats or issues present within a system - any that much such claims are scams. Sites running "System Warning Alert" and similar schemes are typically accessed via redirects caused by intrusive advertisements or Potentially Unwanted Applications (PUAs) already infiltrated into the system.

System Warning Alert scam

When a website promoting the "System Warning Alert" scam is entered, the web page displays several pop-up windows. The top-most pop-up states that the site is requesting users to provide their username and password, due to suspicious activity detected on their IP addresses - allegedly caused by a dangerous system infection. It also urges users to call a free technical support number. The text presented in the window overlaid by the previously described pop-up is identical to that stated in the background page, however, the background page also contains a fake anti-virus report in the right corner. The deceptive message in both the pop-up and background claims that it is a "System Warning Alert". The detected issue is specified as "ERROR # 0xC004FC03" and users are instructed not to ignore this critical alert and call the provided number immediately. The scam proclaims that should this web page be closed - access to the device will be disabled in order to prevent further damage to the user's network. The "alert" is displayed since the computer is notifying that it has been infected with pornographic spyware and other viruses. These nonexistent threats are allegedly already in the process of exfiltrating information, as listed: Facebook and email account log-in credentials, credit card details, photographs and documents stored in the device. The scheme again urges users to call the telephone number in order to contact "expert engineers", who will supposedly walk them through the removal process. This call must be made within five minutes to avoid data loss and having access to the computer disabled. Note that all information provided by "System Warning Alert" is false. Scammers disguise expensive telephone numbers as technical support to trick users into listening to lengthy technobabble while they unknowingly rack up significant phone bills. Additionally, the criminals might attempt to convince people into allowing them access to their systems, which can result in real malware infections and other serious problems. Scammers might also request payment for services rendered and/or try to extract personal information (e.g. names, addresses, emails, banking account and/or credit card details, etc.). Therefore, trusting the "System Warning Alert" scam can lead to financial losses, serious privacy issues and identity theft. You are expressly advised not to trust any claims made by this, or similar, scams and to leave these web pages without delay. In some cases, scam websites can prevent users from closing them. In these cases, terminate the browser process using Task Manager, however, upon reopening the browser, do not restore the previous browsing session, as doing so will reopen the deceptive page.

PUAs can force-open legitimate pages, not just deceptive/scam sites. They can cause unwanted redirects to rogue/untrustworthy, sale-based, compromised and malicious pages, however, these apps also have additional capabilities. Adware-type PUAs can deliver intrusive ad campaigns. The resultant ads redirect to similarly harmful web pages and can even execute scripts to stealthily download/install unwanted software. Other types of PUAs called browser hijackers can modify browsers to promote fake search engines. These rogue web searchers are typically unable to generate unique results, and so they redirect to Google, Yahoo, Bing and other legitimate search engines. Most PUAs can track data. They can monitor users' browsing habits (browsing and search engine histories) and collect personal information (IP addresses, geolocations and other details). This sensitive data is often shared with third parties, seeking to misuse it for profit. To summarize, presence of unwanted applications on systems can endanger device and user safety. You are advised to eliminate all suspect applications and browser extensions/plug-ins immediately upon detection.

"Attention 22 threats found", "WARNING! 36 infections found!!!", and "Activation Security Warning" are some examples of other technical support scams. The internet is rife with various schemes that employ different models to trick users into performing specific actions. Popular scam models include (but are not limited to) warnings about system infections, alerts that an essential piece of software is outdated, fake prize giveaways, amazing offers and deals. Regardless of what these schemes claim, request or demand, their purpose is identical: to generate revenue to the scammers/cyber criminals behind them.

How did potentially unwanted applications install on my computer?

PUAs are proliferated though the download/install set-ups of other programs. This deceptive marketing method of pre-packing regular software with unwanted or malicious additions is called "bundling". Rushing download/installation processes (e.g. ignoring terms, skipping steps, etc.) increases the risk of inadvertently allowing bundled content onto the device. Note that some PUAs have "official" download web pages. Once clicked, intrusive ads can execute scripts to download/install PUAs, without users' permission.

How to avoid installation of potentially unwanted applications

You are advised to research all software prior to download/installation. All downloads should be performed from official and verified sources. Unofficial and free file-hosting websites, Peer-to-Peer sharing networks and other third party downloaders are untrusted, since they can offer deceptive and/or bundled content. When downloading/installing, read the terms, study all available options, use the "Custom/Advanced" settings and opt-out of additional apps, tools, features and so on. Exercise caution when browsing. Intrusive advertisements often seem normal and harmless, however, they can redirect to dubious pages (e.g. gambling, pornography, adult-dating, etc.). If you encounter these ads/redirects, check the system and immediately remove all dubious applications and browser extensions/plug-ins. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
