"Microsoft Important Alert" removal instructions
What is the "Microsoft Important Alert" scam?
"Microsoft Important Alert" is a a tech support scam, promoted on various deceptive webpages. At the time of research, this scheme had been promoted through the legitimate Amazon AWS (Amazon Web Services). The "Microsoft Important Alert" scam claims that users' computers have been infected with "Pornographic Spyware and riskware" and may be blocked to prevent further damage. It must be emphasized that not website can detect/report on threats or issues present in visitors' devices and the aforementioned scheme is not an exception to this. Additionally, this scam is in no way associated with the genuine Microsoft Corporation. These types of scams are designed to abuse users' trust in order to generate revenue for the scammers behind them. Deceptive sites are rarely accessed intentionally, visitors to them typically access them via mistyped URLs, redirects caused by intrusive advertisements or by PUAs (Potentially Unwanted Applications). This software does not need express permission to be installed onto systems; hence, users may be unaware of its presence of their devices.
The "Microsoft Important Alert" scam urges users to call the provided telephone number immediately. This scheme states that if the alert is ignored and the page is closed - access to the visitor's device will be disabled, in order to prevent further damage to the network. Supposedly, the scammers were warned by the visitor's computer that it has been infected with malware (specifically, with pornographic spyware and riskware). Additionally, the scam lists information that is being stolen. Allegedly, users' communication account (email and Facebook) log-in credentials (i.e. usernames and passwords), credit card details and photographs stored on their computers - are in the process of being extracted. To remove the nonexistent infections, users are pushed once again to call the number. The "expert engineers" will aid with the removal process. As mentioned in the introduction, all of the information provided by "Microsoft Important Alert" is false. Trusting technical support scams can lead to a wide variety of issues. Firstly, the fake helplines are usually not toll-free (despite often being presented as such). Scammers typically attempt to gain remote access to their victims' devices. At best, they give bogus advice and cause no damage to the accessed computer. However, it is more common for scammers to remove legitimate anti-virus software and offer fake system protection/cleaning tools, infect devices with actual malware (e.g. trojans, ransomware, etc.), extract private/sensitive content stored within the system, and so on. One of the popular malware choices are RATs (Remote Access Trojans), which ensure stealthy (and potentially, indefinite) remote access and control over victims' computers. Furthermore, tech support scammers ask users to provide personal information themselves (e.g. names, addresses, emails, credit card and banking account details) - by requesting the information to be written down and/or entered into dubious sites that record provided data. The technical support "services" offered by scammers are never free and despite being worthless and/or harmful - tend to be ludicrously expensive. What is more, successfully scammed victims are frequently targeted repeatedly. To summarize, believing the "Microsoft Important Alert" scheme can result in system infections, financial losses, severe privacy issues and even identity theft. It may be impossible to exit a deceptive website by simply closing it; in such cases, the Windows Task Manager must be used to end the browser's process. The next time the browser is opened, it is important not to restore the previous browsing session - as doing so will reopen the scam site.
PUAs are one of the reasons users may experience rogue redirects to various deceptive and malicious webpages. However, these apps can have different/additional heinous abilities as well. Adware-types deliver intrusive adverts, which seriously diminish the browsing activity. Upon being clicked on, the delivered ads redirect to dangerous sites and some can even stealthily download/install software (e.g. PUAs). Browser hijackers are another type of PUAs, they operate by making modifications to browser settings and restricting/denying access to them - in order to promote fake search engines. The promoted web searchers are seldom capable of providing search results, so they redirect to legitimate search engines (e.g. Yahoo, Bing, Google, etc.). Most PUAs (regardless of type) spy on users' browsing activity. Data of interest includes: browsing and search engine histories, IP addresses, geolocations and other personally identifiable information. The collected data is then shared with and/or sold to third parties (potentially, cyber criminals). To ensure device integrity and user privacy, it is crucial to remove all suspicious applications and browser extensions/plug-ins without delay.

"ERROR # 0x6a4-0xf9fx3999", "Activation Failed! (Error Code 001)", "Windows Error Code: DLL011150", "Covid19 Warning Alert" - are some examples of other technical support scams. The Internet is rife with various schemes that use different models to lure potential victims. Popular scam models include (but are not limited to): warnings that the device is infected or at risk, alerts that an essential software product is outdated or missing, fake prize giveaways and raffles, unbelievable offers and deals. Regardless of how scams operate, the end-goal is the same - to generate revenue for the scammers / cyber criminals behind them. Therefore, it is strongly advised to exercise caution when browsing.
How did potentially unwanted applications install on my computer?
Select PUAs have "official" download pages, which are often promoted by deceptive/scam websites. These applications are also distributed via download/installation setups of other programs. This false marketing tactic is called "bundling". Rushed download/installation processes (e.g. ignored terms, used "Easy/Express" settings, etc.) - increase the risk of unintentionally allowing dubious and/or bundled content into the system. Intrusive advertisements proliferate PUAs as well. Once clicked on, the ads can execute scripts to download/install this software without user consent.
How to avoid installation of potentially unwanted applications?
It is recommended to research products prior to download/installation and/or purchase. All downloads must be done from official and verified sources. Since untrustworthy channels, e.g. unofficial and free file-hosting sites, Peer-to-Peer sharing networks and other third party downloaders - commonly offer harmful and/or bundled content. 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, features, and so forth. Intrusive adverts appear legitimate, however they redirect to various unreliable and questionable webpages (e.g. gambling, adult-dating, pornography, etc.). In case of encounters with such ads and/or redirects, the system must be inspected and all suspect applications and browser extensions/plug-ins detected - immediately removed from it. If your computer is already infected with PUAs, we recommend running a scan with Malwarebytes for Windows to automatically eliminate them.
