What is Crabeu.info ads?

Crabeu.info is a rogue website that shows misleading virus infection messages

Crabeu.info is a fake website that shows misleading messages

Crabeu.info is a malicious website created by scammers to mislead users into downloading potentially dangerous software. Upon entry, they are immediately shown what looks like a virus scan progress bar for a few moments – it also bears the name of a reputable security vendor Norton. Users are then quickly shown the alleged results of the scan, which implies that several viruses have been found on the system.

In reality, the scan and its results are entirely fake, and Norton has nothing to do with this scam. The main goal of crooks is to make people click on affiliated links and make them install software, which translates into profits. Redirects to download pages might also not be secure, and users may end up infecting their systems with malware in the process.

Crabeu.info also asks users to enable push notifications. If you have accidentally clicked the “Allow” within the prompt, you would be getting intrusive pop-ups filled with malicious links on a regular basis. We explain how to deal with this phenomenon in the removal section below.

Browser-based scams are extremely common and come in various shapes and forms. Technical support or fake virus infection messages are among the most widespread scamps populated by websites like Crabeu.info, Bostewsom.shop, Protectpc.xyz, Performdevelopedgreatlythefile.vip, and many others.

The mentioned websites, among others, are actively distributing the same phishing^[1] content and always use either McAfee or Norton names in their scam schemes. Usage of widely recognized company names is a well-known social engineering^[2] tactic used to spread malware, steal user accounts, and more.

The scam scheme

Upon the entry to Crabeu.info, users are trying to be convinced that there's a security scan going on. Within a few brief moments, people are shown the following message:

Your PC is infected with 5 viruses!

ACTION REQUIRED

Your McAfee Subscription Has Expired!
Renew now to keep your PC protected.
If your PC is unprotected, it is at risk for viruses and other malware.

Evidently, scammers are trying to convince users that their devices have been infected with malware that needs to be removed. Here they claim that the security software license has expired, regardless if one actually possessed Norton's license in the first place.

Whenever you see notifications that claim that your device is infected, please disregard them immediately and close down the tab they're shown in. While you might not necessarily be redirected to malicious websites, you can never know for sure, so the best thing here is not to interact with any scam content at all.

Adware and its removal

Adware^[3] is deceptive software that manages to sneak into users' devices without them noticing. Alternatively, users might install an adware-type program without knowing its suspicious behavior, believing it's a regular app.

As a result, many users aren't even aware that they have potentially unwanted software on their systems, although those affected can see symptoms such as intrusive ads on visited websites, unexpected redirects, phishing content encounters, changes to browser settings, and more. In some cases, no visible symptoms are present, or they are unnoticeable.

Thus, we recommend you check your system thoroughly – first by uninstalling all the unwanted apps from the system and then the browser. The best way to remove the most aggressive adware and malware are by scanning the device with anti-malware software, such as SpyHunter 5Combo Cleaner or Malwarebytes, however.

Windows

• Enter Control Panel into the Windows search box and hit Enter or click on the search result.
• Under Programs, select Uninstall a program.
• From the list, find the entry of the suspicious program.
• Right-click on the application and select Uninstall.
• If User Account Control shows up, click Yes.
• Wait till the uninstallation process is complete and click OK.

Mac

While moving apps into Trash is how you delete most normal applications, adware tends to create additional files for persistence. Thus, you should look for .plist and other files that could be related to the virus. If you are not sure, skip this step entirely.

1. From the menu bar, select Go > Applications.
2. In the Applications folder, look for all related entries.
3. Click on the app and drag it to Trash (or right-click and pick Move to Trash)

To fully remove an unwanted app, you need to access Application Support, LaunchAgents, and LaunchDaemons folders and delete relevant files:

1. Select Go > Go to Folder.
2. Enter /Library/Application Support and click Go or press Enter.
3. In the Application Support folder, look for any dubious entries and then delete them.
4. Now enter /Library/LaunchAgents and /Library/LaunchDaemons folders the same way and terminate all the related .plist files.

Usually, you can uninstall extensions from your browser by clicking the “Extensions,” although this might not always be possible. In such a case, you should access the settings menu of your browser and eliminate the suspicious extensions from there (note that even trustworthy apps might become rogue after they are sold to malicious parties).

Your next task your be to clean your browsers from cookies and other trackers. The easiest way to do this is by employing FortectIntego utility, although a manual solution is also possible:
