If you are wondering what actually happened to your Windows device, there are two explanations – you either visited a malignant web page that redirected you to “Error Code: RNN7892” phishing site, or you have malware residing on your computer. By saying malware, we mean the program that sends you these bogus messages via your browser, but not viruses that these pop-up messages falsely inform you about.

It is important to identify tech support scams and not fall for their tricks. If you call them, they typically want to get remote access to your computer to fix “issues” that ostensibly pose a risk to your computer’s safety. On Windows computers, they start by running Tree command in CMD.exe, which just displays all directories on the screen. Since the computer quickly shows all directories, an inexperienced user might start thinking that the computer system is being scanned and that it is safe to allow the “technician” do it. In general, scammers want to gain victim’s trust and slowly convince him to obtain products or services from them. Later on, they ask the victim to enter a particular website and provide full name, address, and even credit card details on it to “purchase” certain service, software, or another absolutely useless product. Keep in mind that scammers only want your money, so you should stay away from products they recommend buying! Instead, use a reliable software, for instance, ReimageIntego and remove suspicious programs from your PC right away.

Escaping tech support scams

In some cases, it is enough to visit a malicious domain to be automatically redirected to a malicious site that displays such hideous pop-ups. In such situations, it is enough to restart the browser by closing it and reopening it while holding Shift key and reset the browser later on. However, there are a lot of programs that hijack computer system, stay silent and display annoying pop-ups whenever the user launches an affected web browser. They typically enter the computer system when the user installs a hazardous software package, opens a malicious email attachment or agrees to install a fake software update. To prevent malware attacks, don’t install programs using Default or Standard settings and use your common sense when browsing the Internet. Don’t click on ads that promise you to make you rich or that say that you have just won 1 billion dollars for nothing. Also, never open files that unknown people send you to you via email. You can never know what hides in these attachments!

After uninstalling this potentially unwanted program (PUP) and fixing each of your web browsers, we recommend you to scan your PC system with a reputable anti-spyware.

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
