"ERROR CODE 72" scam removal instructions
What is the "ERROR CODE 72" scam?
"ERROR CODE 72" is a scam run on deceptive webpages. It has been observed being promoted using azurewebsites[.]net - Microsoft Azure website-hosting platform. "ERROR CODE 72" is classified as a technical support scam. This scheme claims that the device has been infected with several high-risk viruses and urges users to call a fake tech support line. It must be emphasized that no website can actually detect threats/issues present in systems; hence, any sites that make such claims are scams. Few visitors to deceptive/scam pages access them intentionally, most get redirected to them by intrusive advertisements or by PUAs (Potentially Unwanted Applications), already installed onto the system.
Once a website promoting "ERROR CODE 72" is accessed, it displays a pop-up window. It states that "Microsoft" has protected users' computers. They are urged to call a free helpline. The text presented in the background page claims that the device's screen has been disabled, due to the system being infected with multiple viruses. These threats are listed as: an unspecified trojan, CSRSS.EXE trojan, pornographic spyware and phishing malware infections. Users are asked to call the provided telephone number within five minutes. They must call the helpline to prevent access and data loss - by following the removal instructions provided by "expert engineers". Typically, the "free" technical support lines are expensive and the scammers attempt to keep users talking for as long as possible. Alternatively, the cyber criminals can trick users into allowing them access and control over the supposedly infected device. The system might also suffer genuine malware infections, through alleged anti-virus tools and other software the criminals may offer. Other purposes of such schemes can be to demand payment for fake "services rendered" or to extract personal information from users (e.g. names, addresses, emails, banking account or credit card details, etc.). To summarize, trusting "ERROR CODE 72" scam can result in system infections, financial losses, severe privacy issues and even identity theft. Therefore, it is recommended to simply ignore the scheme and close the webpage displaying it. In some cases, it may be impossible to close a deceptive site; hence, the Windows Task Manager is to be used to end the browser's process. Additionally, upon reopening the previous session must not be restored - so as not to reopen the scam page (or cause the website that originally redirected to it - to do so again).
Aside from force-open various untrustworthy and malicious sites, PUAs can have other/additional abilities. Adware-type unwanted apps enable the placement of intrusive advertisements (e.g. pop-ups, banners, coupons, surveys, etc.) on any visited website. These ads diminish the browsing experience. Furthermore, upon being clicked, intrusive adverts redirect to harmful pages and some can even stealthily download/install software (e.g. PUAs). Another type of PUA, called browser hijackers - modify browsers in order to promote fake search engines. These promoted web searchers are rarely capable of providing search results, so they tend to redirect to Google, Yahoo, Bing and other legitimate search engines. What is more, most PUAs have data tracking abilities. They can monitor browsing activity (URLs visited, pages viewed, search queries typed, etc.) and collect personal information extracted from it (IP addresses, geolocations and other details). PUA developers often monetize this vulnerable data by sharing it with and/or selling it to third parties. Therefore, to ensure device integrity and user safety, all suspect applications and browser extensions/plug-ins immediately upon detection.

"Killer's IP Address", "VIRUS ALERT FROM Windows", "Windows firewall has blocked some features of this program" and "WIN.DLL011150 Error" are some examples of other technical support scams. There are thousands of deceptive webpages on the Web. They use social engineering and scare tactics to trick users into performing certain actions. Popular scam models include: warnings that the device is infected, alerts that an essential piece of software is outdated, fake prize giveaways, unbelievable offers/deals, and so on. These schemes try to push users into: calling expensive "helplines", download/install and/or purchase untrustworthy or malicious software, pay bogus fees, reveal personal information, etc. Regardless of what scams claim, the end-goal is the same - to generate revenue for the scammers / cyber criminals behind them.
How did potentially unwanted applications install on my computer?
PUAs can be downloaded/installed together with other software. This deceptive marketing technique of pre-packing regular products with unwanted or malicious additions - is termed "bundling". Rushed download/installation processes (e.g. ignored terms, used pre-set options, etc.) - increase the risk of unintentionally allowing dubious and/or bundled content into the device. Some PUAs have "official" download webpages, which are commonly promoted by scam sites. Intrusive advertisements proliferate these applications as well. Once clicked on, they can execute scripts to download/install PUAs without user permission.
How to avoid installation of potentially unwanted applications?
It is recommended to research software before download/installation and/or purchase. All downloads must be done from official and verified sources. Untrustworthy channels, like: unofficial and free file-hosting websites, P2P sharing networks (BitTorrent, Gnutella, eMule, etc.) and other third party downloaders - offer bundled content; therefore, they are advised against use. When downloading.installing, it is important to read terms, explore all available options, use the "Custom/Advanced" settings and opt-out from additional apps, tools, functions, and so on. Intrusive adverts typically appear legitimate and harmless, however they redirect to various questionable pages (e.g. gambling, pornography, adult-dating and others). In case of encounters with such ads/redirects, users must inspect the system and immediately remove all suspicious applications and browser extensions/plug-ins from it. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
