Screenshot of "Unknown Security Breach" pop-up virus

“Unknown Security Breach” pretends to be analert from Internet Service Provider that informs about Malware error 895-SYSTEM32.EXE Failure. Malware uses Microsoft’s credentials, provides various error names and provides support number 1-844-346-3716. However, it’s a tech support scam.[1]

This fake message is delivered by a malicious website. Typically various adware programs redirect users to a technical support scam site. These applications usually are installed bundled with freeware. On the affected device, such programs might disturb browsing session with redirects to dangerous or promotional sites and track information about users.

When users end up “Unknown Security Breach” scam site, they learn about computer infection. However, we want to point out that it’s a fake warning. Any dangerous trojan or malware haven’t attacked your device. Thus, you should leave this website without calling fake Microsoft technicians.

Cyber criminals use various computer terms, names of the programs and errors in order to scare victims. The “Unknown Security Breach” virus tells that some “harmful virus” affected the system and caused these problems:

  • missing .net frame work file,
  • Malware Error 895-SYSTEM32.EXE Failure,
  • Error Code 0x214aL,
  • ERROR CODE 0xa297sa,
  • BSOD: DllRegistrationErrorCode: o0acxfasf.

However, none of these issues are real. Cyber criminals just want to create an image that your computer, privacy and sensitive information are in great danger. The fear of losing credit card details, passwords, and other confidential information, might motivate inexperienced computer users to call a provided phone number.

We want to remind that Microsoft does not have a phone support line. What is more, security alerts never appear on Google Chrome, Mozilla Firefox, Microsoft Edge or Internet Explorer. Only security program installed on your PC can report about detect threats, and these alerts appear in the program window.

Thus, you should remove “Unknown Security Breach” pop-up virus as soon as it shows up on your browser. We recommend dedicating this task for ReimageIntego. This anti-malware not only deletes adware that is responsible for redirects to the scam site but protects your machine from similar infections in the future.

Of course, the primary purpose of the ”Unknown Security Breach” removal is stopping annoying activities on the browser. Indeed, redirects to various websites diminish browsing activities. However, the ad-supported program might also deliver aggressive ads that lead to harmful domains and track information about you. Thus, elimination protects your device from dangerous viruses[2] that are lurking on the web.

Redirects to scam website might start after incorrect installation of freeware

According to the recent research data, most of the time various potentially unwanted programs (PUPs) are initiating redirects to “Unknown Security Breach” tech support scam website. These ad-supported applications usually sneak into the device via software bundle.

Any freeware or shareware can be a software package. Thus, before installing new programs, you have to check whether it’s a single program or not by choosing “Advanced” or “Custom” installation method. Keep in mind that “Recommended” or “Quick” options do not include such feature.

During the installation, you might discover the checkbox with pre-selected additional applications. Unmark them all. It prevents them from entering the system and causing problems on the computer.

Unfortunately, the majority of computer users in America, China,[3] and European countries rely on Quick installation method. We want to point out that correct software installation takes less time than a removal of PUPs or malware.

Protect your privacy – employ a VPN

There are several ways how to make your online time more private – you can access an incognito tab. However, there is no secret that even in this mode, you are tracked for advertising purposes. There is a way to add an extra layer of protection and create a completely anonymous web browsing practice with the help of Private Internet Access VPN. This software reroutes traffic through different servers, thus leaving your IP address and geolocation in disguise. Besides, it is based on a strict no-log policy, meaning that no data will be recorded, leaked, and available for both first and third parties. The combination of a secure web browser and Private Internet Access VPN will let you browse the Internet without a feeling of being spied or targeted by criminals. 

No backups? No problem. Use a data recovery tool

If you wonder how data loss can occur, you should not look any further for answers – human errors, malware attacks, hardware failures, power cuts, natural disasters, or even simple negligence. In some cases, lost files are extremely important, and many straight out panic when such an unfortunate course of events happen. Due to this, you should always ensure that you prepare proper data backups on a regular basis.

If you were caught by surprise and did not have any backups to restore your files from, not everything is lost. Data Recovery Pro is one of the leading file recovery solutions you can find on the market – it is likely to restore even lost emails or data located on an external device.
