Ransomware Detected Scam

Also Known As: "Ransomware Detected" virus
Type: Adware
Damage level: Medium

What is Ransomware Detected?

"Ransomware Detected" is a fake pop-up error message displayed by a malicious website that users often visit inadvertently - they are redirected by potentially unwanted programs (PUPs) that infiltrate systems without consent. Many PUPs also deliver intrusive online advertisements and record information relating to users' Internet browsing activity.

Ransomware Detected adware

The pop-up message states that the system has been infected with a ransomware-type virus and, therefore, private details (logins/passwords, banking information, etc.) are at risk. It goes on to state that the malware must be eliminated immediately by contacting the "Microsoft Help Desk" via a toll-free telephone number ("61-(08) 9677 5482") provided.

These "certified technicians" then supposedly guide users through the malware removal process. Bear in mind, however, that the people behind the "Ransomware Detected" pop-up are cyber criminals. This error is a scam. They attempt to scare and trick users into calling and paying for technical support that is not required. The error message is fake.

Therefore, never attempt to contact these people. As mentioned above, PUPs are also likely to deliver various ads such as banners, coupons, pop-ups, etc. These often conceal underlying website content, thereby significantly diminishing the browsing experience.

In addition, the ads often lead to malicious websites and even accidental clicks can result in high-risk adware or malware infections. PUPs also monitor web browsing activity by gathering IP addresses, URLs visited, pages viewed, queries entered into search engines, and other similar information.

The collected data is later shared with third parties (potentially, cyber criminals) who misuse private information to generate revenue. Therefore, the presence of information-tracking applications can lead to serious privacy issues or even identity theft.

There are numerous fake errors that share similarities with "Ransomware Detected" including Your Windows Is Infected, Error Virus - Trojan Backdoor Hijack, and Windows 10 Technical Support, etc. These pop-ups also claim that the system is damaged in some way, however, they have an identical purpose: to generate revenue for the developers.

These errors are fake and should be ignored. You can remove them simply by closing the web browser. All claims to provide 'useful features' are merely attempts to give the impression of legitimacy. In fact, these PUPs cause unwanted redirects, deliver intrusive ads, and continually record private information.

How did adware install on my computer?

Cyber criminals proliferate PUPs by employing a deceptive marketing method called "bundling". Research shows that users often rush when downloading and installing software. Aware of this, developers hide bundled programs within the "Custom" or "Advanced" settings. Rushing and skipping this section often leads to inadvertent installation of rogue software.

How to avoid installation of potentially unwanted applications?

There are two simple steps you should take to prevent system infiltration by PUPs: 1) closely analyze each download/installation step using the "Custom" or "Advanced" settings, and; 2) opt-out of all additionally-included programs. The key to computer safety is caution.
