Error Code 09-986-6321 POP-UP Scam

Also Known As: "Error Code 09-986-6321" virus
Damage level: Medium

What is "Error Code 09-986-6321"?

"Error Code 09-986-6321" is a fake error alert (notification) that pops up only on deceptive, dubious websites. Typically, scammers use websites of this type to extort money from innocent people. They attempt to make users believe that there is a problem (in this case, an error) that must be fixed immediately. They encourage them to make contact to address the issue.

This is merely a scam and should be ignored. People do not generally visit websites that display fake errors or virus alerts intentionally - they are redirected to them by potentially unwanted apps (PUAs) installed on their browsers or operating systems. Most PUAs feed users with intrusive, unwanted advertisements and collect information relating to browsing activity.

Error Code 09-986-6321 scam

The "Error Code 09-986-6321" scam (website) runs a JavaScript file that forces the browser to use 100% CPU resources and makes it unresponsive. This supposedly makes is easier for scammers to trick people into believing that there is an issue with their computers/operating systems.

A pop-up window displayed on this deceptive page may seem to be an official notification from Microsoft (or the Windows Operating System). It states that a computer and network connection was blocked, since Windows Firewall has detected suspicious activities relating to the user's IP address.

It urges people not to restart their computers, since this might cause serious damage to the system and data stored on it. Additionally, it states that a third party was attempting to access the user's logins, banking details and might be tracking web browsing activities.

To protect their personal details and to fix these problems, people are encouraged to immediately contact "Microsoft Certified Technical Support Help Desk" via the 1-877-220-8359 number. These claims are false and should not be taken seriously. The best option is to close the browser.

Alternatively, end the process using Task Manager if it cannot be closed (due to the JavaScript that this deceptive website runs). To avoid visiting this site again, do not restore the previously closed session when the browser is next opened.

Unwanted applications that open websites of this type also deliver intrusive ads such as coupons, banners, surveys, pop-ups, and so on. They display the ads through tools that enable placement of third party graphical content on any site. Therefore, they conceal underlying content of visited websites.

Click them often leads to dubious web pages or having unwanted apps downloaded and installed. PUAs also perform information tracking. They collect information such as IP addresses, entered search queries, URLs of visited websites, geo-locations, and so on.

Unfortunately, some of these apps target personal details. PUA developers share the data with third parties (potentially, cyber criminals) who misuse it to generate revenue. To avoid privacy, browsing safety issues, or other problems, uninstall all PUAs immediately.

Some examples of other scams similar to "Error Code 09-986-6321" are "Error XR01F5", "Windows Defender Alert (0x3e7)", and "Virus Support Alert". Typically, scammers use them to trick people into purchasing products or services that, according to them, will remove viruses, fix errors and solve other problems.

Most PUAs are very similar and share the same purpose: to generate revenue for their developers by collecting information, causing redirects to dubious pages, and feeding users with intrusive advertisements.

How did potentially unwanted applications install on my computer?

People often install unwanted apps inadvertently through intrusive advertisements or when software developers use a deceptive marketing method called "bundling". Bundling is placement of PUAs in installation or download set-ups of other software. Developers hide them in "Advanced", "Custom" and other options, and they do not disclose information about their inclusion.

Despite this, most PUAs are installed when people download and install software without checking additional options/settings (they leave them unchanged) or click ads that should not be trusted.

How to avoid installation of potentially unwanted applications?

Avoid downloading software from untrustworthy, unofficial sources, using torrent clients (and other Peer-to-Peer networks), third party downloaders and so on. Use direct links and official websites. Do not download or installation without checking "Custom", "Advanced" and other similar settings.

Opt-out of additionally-included (bundled) apps, and only then proceed to the next step or finish downloading or installing software. Intrusive ads often redirect users to untrustworthy (potentially malicious) websites relating to gambling, pornography, adult dating, and so on. These ads should not be clicked.

If you encounter these advertisements or unwanted redirects, check installed browser apps (extensions, add-ons, plug-ins) and remove any unknown, unwanted entries immediately. Unwanted programs installed on the operating system should also be uninstalled.

If your computer is already infected with PUAs, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate them.

How to identify a pop-up scam?

Pop-up windows with various fake messages are a common type of lures cybercriminals use. They collect sensitive personal data, trick Internet users into calling fake tech support numbers, subscribe to useless online services, invest in shady cryptocurrency schemes, etc.

While in the majority of cases these pop-ups don't infect users' devices with malware, they can cause direct monetary loss or could result in identity theft.

  • Statements that you won something - If you haven't participated in a lottery, online competition, etc., and you see a pop-up window stating that you won.
  • Computer or mobile device scan - A pop-up window that scans your device and informs of detected issues - is undoubtedly a scam; webpages cannot perform such actions.
