Malwarebytes blocks coomer.su because it classifies the domain as associated with riskware. Malwarebytes says the platform, which hosts user-shared explicit content, has been abused to distribute malicious files. That domain-level block does not prove that your computer is infected or that every file on the site is malicious. If you saw the alert, record the connection details, run a Malwarebytes scan, and investigate further if the blocks keep returning.
Why did Malwarebytes block coomer.su?
On its “Malwarebytes Threat Alert | coomer.su” detection page, Malwarebytes labels the domain as associated with riskware. The page explains that coomer.su provides a platform for sharing explicit content and that the platform has been abused to share malicious files. This is Malwarebytes’ stated reason for blocking the domain; it is not a finding that every page, download, or visitor is infected.
Does the alert mean my computer is infected?
No. A blocked-website notification establishes that Malwarebytes Web Protection stopped a connection it considered potentially harmful. By itself, it does not establish that malware ran on the device, that a file was downloaded, or that the device is compromised.
The alert is also not enough to call the detection a false positive. The appropriate conclusion is narrower: Malwarebytes has blocked the domain under its current riskware classification, and the device should be checked if the connection was unexpected or keeps recurring.

What information is in a Malwarebytes website-block notification?
Malwarebytes’ support guidance for Malwarebytes for Windows v4 says the notification can identify:
- the blocked domain;
- the IP address;
- the port;
- whether the traffic was inbound or outbound; and
- the file or process that attempted the connection.
Those details help distinguish an accidental browser request from a background process, extension, installed application, or other source. Interface labels and behavior may differ in other Malwarebytes versions, so do not assume Windows v4 instructions apply unchanged elsewhere.
Rank #2
What to do after seeing the coomer.su alert
- Record the notification. Note the domain, IP address, port, traffic direction, and file or process shown before dismissing it.
- Run a Malwarebytes scan. Malwarebytes recommends scanning the device after a website-blocked notification. Let the scan finish and follow the product’s remediation instructions for anything it detects.
- Review the triggering process if the block was unexpected. An outbound connection may point to a browser tab, extension, application, or background process attempting to reach the domain. An inbound entry describes traffic arriving at the device; it is not, on its own, proof that the device was infected.
- Escalate recurring blocks. If notifications continue after the scan, Malwarebytes advises contacting Support so the source of the connection can be isolated.
Should you add coomer.su to Malwarebytes’ Allow List?
The coomer.su detection page documents an Allow List option. Adding a URL there changes Malwarebytes’ protection behavior for that allowed address; it does not demonstrate that the address is safe. Do not bypass the warning merely because a page is inaccessible. An exception should be considered only for a specific, well-supported reason, with an understanding that it removes the block for that URL.
How to interpret one-time versus recurring blocks
A single notification
A one-time block can reflect a page, redirect, advertisement, extension, or application that attempted a connection. Preserve the notification details and complete the recommended scan rather than inferring infection from the domain name alone.
Rank #3
Blocks that return after scanning
Repeated alerts are more useful diagnostically because the notification may identify the same process or file each time. Check that process and use Malwarebytes Support guidance to investigate it. Recurrence still does not prove that coomer.su itself infected the device; it shows that something on the device is continuing to request the blocked connection.
What Malwarebytes’ classification does—and does not—say
| Established by the alert | Not established by the alert alone |
|---|---|
| Malwarebytes associates coomer.su with riskware. | That every visit causes an infection. |
| Malwarebytes says the platform has been abused to share malicious files. | That every file hosted on the domain is malicious. |
| Web Protection blocked a potentially harmful connection. | That malware executed on your computer. |
| The notification may identify direction, IP, port, and the initiating file or process. | That the domain name alone identifies the cause of the connection. |
Bottom line for the “is this a false alert?” question
Treat the message as a precautionary domain block, not as a diagnosis. Malwarebytes’ current page gives a riskware classification and a rationale involving abuse for malicious-file sharing. Follow the Windows v4 support sequence—inspect the notification, scan the device, and contact Malwarebytes Support if blocks continue—without assuming either universal site-wide malware or a confirmed infection.
Source and currency note
The domain-specific explanation comes from Malwarebytes’ “Malwarebytes Threat Alert | coomer.su” page. The notification interpretation and follow-up steps come from Malwarebytes Help Center’s “Received a Website Blocked notification from Malwarebytes for Windows v4.” Malware classifications and product instructions can change, and the coomer.su detection page reviewed does not state a publication date; check the current Malwarebytes pages for the latest status.
