ERROR # 0x6a4-0xf9fx3999 scamERROR # 0x6a4-0xf9fx3999 is a fake notification claiming that users' machines are infected with "Storm Worm" and "Riskware"

ERROR # 0x6a4-0xf9fx3999 scam is one of thousands of tech support scams spreading around the internet. Once users visit a malicious website, they are presented what seems to be a warning from Microsoft. It claims that the computer login will be disabled due to an alleged infection of “Storm Worm” and “Riskware,” and that bank account details, email, social media logins, and images stored on the machine are at risk of being stolen/compromised.

If you are asking how this terrible ERROR # 0x6a4-0xf9fx3999 virus infection managed to get into your PC, you should not look far for answers – the alert is a simple page designed by cybercriminals to scare users and make them call the provided phone number. Once they are on the line, they will be further fed fake facts about their computer health state, so that money could be later extorted for the “provided help.”

 ERROR # 0x6a4-0xf9fx3999 scam can be encountered on multiple different website URL's, e.g., “” on any web browser, including Google Chrome, Mozilla Firefox, MS Edge, or Internet Explorer. In other words, the scam is browser-based, and notification has nothing to do with Windows system alerts you might be accustomed to seeing (the page attempts to imitate Windows Blue Screen of Death).

However, we can assure you that ERROR # 0x6a4-0xf9fx3999 scam is fake and has nothing to do with real Microsoft technicians. There are several similar scams that aim to mislead users in the same way by pretending to be tech support from Microsoft – a few examples include:

While these scams might look slightly different and provide different messages, they are fundamentally identical. They all attempt to imitate legitimate Microsoft website or alerts, claim about virus infections/personal information compromise, and ask to call the provided number to resolve the seemingly disastrous situation.

Upon entering a malicious site, ERROR # 0x6a4-0xf9fx3999 scam message would popup, which is almost identical to the one presented in the background

** MicroSoft Alert **
ERROR # 0x6a4-0xf9fx3999(3)

As you can see, the ERROR # 0x6a4-0xf9fx3999 popup is designed to scare users and make them panic – this is one of the main social engineering tactics that is surprisingly very effective when it comes to fraud. In reality, the “Storm Worm” does not exist, and “riskware” is just a name for a particular malware type.

Malicious actors behind the scam attempt to exploit inexperienced users by stuffing their minds with words they are not familiar with. Indeed, ERROR # 0x6a4-0xf9fx3999 might seem like something Microsoft would use to describe legitimate errors with. However, you should always keep in mind that real company would never ask you to call a provided tech support number – this is generally true for all the companies.

ERROR # 0x6a4-0xf9fx3999 scam virusERROR # 0x6a4-0xf9fx3999 is a tech support scam that asks users to call fake support number to eliminate the alleged infections and prevent personal information compromise

Unfortunately for those who get tricked by scammers, the ordeal might end up pretty badly. As soon as users call the allegedly toll-free number +1-844-311-7591 (which might actually be a number charged at premium rate), they will be immediately told that they have a serious problem. As the call progresses, crooks might ask callers to provide remote access to their devices, ask them to download malicious software or ask them for credit card details.

Thus, you should not fall for this, and remove ERROR # 0x6a4-0xf9fx3999 scam from your screen as soon as you see it. If you are incapable of doing so, you should call up the Task Manager and shut down the process of Google Chrome, Mozilla Firefox, or another browser that you are using.

While ERROR # 0x6a4-0xf9fx3999 alert might be encountered after being redirected from another website, random redirects can indicate that there is an adware program installed on your system. These potentially unwanted programs typically find their ways into users' machines without asking for a direct permission, and then begin to show intrusive advertisements, inject popups, redirect to suspicious or malicious websites, etc.

Therefore, ERROR # 0x6a4-0xf9fx3999 removal might consist of adware/malware elimination – it can be performed manually as per instructions below or automatically with security tools such as SpyHunter 5Combo Cleaner or Malwarebytes. Additionally, experts recommend performing additional scans with repair tools such as Reimage Reimage Cleaner Intego.

Tips to avoid being scammed online

Fraud has been around for hundreds of years, so there is no surprise there that the malicious practice was transferred to online sphere as soon as there was a possibility for that to happen. Unsurprisingly, cybercriminals use various tactics to install malware on users' devices, steal their personal information, or scam them and and make them pay for services that do not exist or a re of a horrendous quality.

There are several ways of how you can get tricked online. Crooks employ built-in features to deliver misleading content to users all the time. For example, a page can be constructed in a way to look like a legitimate login page of MS Outlook – users who visit it might believe that it is genuine, and provide their credentials to cybercriminals without realizing it. Website spoofing, along with email spoofing, are among the most popular techniques that result in malware infiltration for thousands of users.

Tech support scams, however, are much easier to recognize, as they are fundamentally flawed in many ways. Here's what you should look out for:

  • Claims that your computer is infected with viruses, trojans, worms, or other malware;
  • All personal and sensitive information, such as Facebook login, banking details, and other data, is being leaked by cybercriminals;
  • Fake virus names, error code names;
  • A threat of consequences (“your computer will be corrupted,” “your information will be stolen,” “your hard drive will be corrupted,” etc.)
  • A phone number that is meant to be used for resolving all the issues (typically varies to prevent being caught by authorities).

Also, you could employ powerful security software with real-time protection feature that would warn you about spoofing, phishing, tech support scam, and other malicious websites.

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.


Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
