System Notification! Scam

What is System notification!?

"System notification!" is a fake error message displayed by a malicious website. Users often visit this site inadvertently - they are redirected by various potentially unwanted programs (PUPs). Research shows that PUPs infiltrate systems without users' consent ("bundling" method).

In addition, they deliver unwanted advertisements and continually record information relating to users' Internet browsing activity.

According to "System notification!", suspicious activity has been detected on the computer. It is also stated that if the error pop-up is closed, computer access is disabled. To resolve this problem, users are encouraged to contact technical support via the telephone number ("+44-800-090-3858") provided. They are then supposedly guided through the fixing process.

Be aware, however, that "System notification!" is a scam. Cyber criminals attempt to trick victims into calling and paying for technical services that are not required. We strongly advise you to ignore this error message and close it immediately. As mentioned above, PUPs generate various intrusive advertisements.

To achieve this, developers employ a "virtual layer" - a tool that enables placement of third party graphical content on any site. Therefore, displayed ads often conceal underlying content, thereby significantly diminishing the web browsing experience. Furthermore, some lead to malicious websites and even accidental clicks can result in high-risk adware or malware infections.

Another downside is information tracking. PUPs gather IP addresses, URLs visited, pages viewed, search queries, mouse/keyboard activity, etc. The collected data might contain personal details that developers share with third parties (potentially, cyber criminals) who misuse private details to generate revenue.

Thus, the presence of information-tracking apps can result in serious privacy issues or even identity theft. All potentially unwanted programs must be uninstalled immediately.

"System notification!" is virtually identical to Invalid Partition Type Was Detected, System Has Detected Intrusion, Microsoft Warning Alert, and dozens of other fake errors. 

All state that the system is infected or damaged in certain ways, however, as with "System notification!", these error messages are designed only to generate revenue for the developers and should never be trusted. Potentially unwanted programs also have an identical purpose.

By offering various 'useful features', they attempt to give the impression of legitimacy - in fact, their only purpose is to generate revenue for the developers, whilst regular users receive no value. Rather than providing any of the functionality promised, PUPs cause unwanted redirects, collect personal information, and deliver various intrusive online advertisements.

How did adware install on my computer?

Developers proliferate PUPs by employing a deceptive marketing method called "bundling" - stealth installation of third party applications with regular software/apps. Developers hide bundled programs within the "Custom" or "Advanced" settings of the download/installation processes.

Rushing these processes and skipping steps exposes systems to risk of various infections and compromises users' privacy.

How to avoid installation of potentially unwanted applications?

To prevent system infiltration by PUPs, be very cautious during the download/installation processes. Closely analyze each step using the "Custom" or "Advanced" settings. Furthermore, decline offers to download/install additional applications.
