It comes as no surprise Diegocosta.stream is a dangerous website. The Internet is currently full of such domains that bring along nothing but trouble. Diegocosta.stream will attempt to trick you into installing a brand new browser extension. However, agreeing to install this plugin is the very last thing you should do. You’re dealing with a nasty cyber scam which could end badly. You see, the Diegocosta.stream website is only part of your life to serve hackers’ purposes. Its pop-ups stubbornly insist that you “add extension to leave”. Keep in mind that this add-on is extremely malicious and problematic. Ignore the devious pop-ups to save yourself a hassle. Agreeing to install the plugin leads to various issues. For starters, your browsers get hijacked. You get redirected to unknown, unsafe websites. You’re also about to be bombarded with irritating, useless commercials. After all, that’s what you could expect out of a questionable plugin like this one. Hackers’ extension allows them to take over your once peaceful online activities. Why do crooks aim at your browsing experience? Because this is one notoriously easy way to gain illegitimate profit. Are you familiar with the pay-per-click mechanism? Cyber criminals definitely are. They are aware that injecting your browsers would let them make money. Furthermore, their devious profit comes directly at your expense. You’re the one who ends up exposed to threats. You’re the one who is left unable to surf the Web. Keep in mind that none of the pop-ups is reliable because your safety is irrelevant to crooks. The one thing they are interested in is gaining profit. That means some of these commercials could turn out to be harmful. Unfortunately, there is no telling which ad is safe and which one is corrupted. If you want to find out for sure, you have to click the pop-up open. Clicking may seriously worsen your already bad situation, though. Thanks to hackers’ shenanigans, you’re one click away from malware. Remember, there are plenty of dangerous programs out there. You could accidentally install more infections and make the mess greater. Avoid anything suspicious you come across now that you have a tricky plugin added. That includes random pop-up ads, software updates, third-party commercials. Put your security first. Restrain yourself from clicking what you find untrustworthy and get rid of the plugin.

How did I get infected with?

This website could have used a key generator (key-gen) or software cracking. In the future, always keep an eye out for malicious pages. Those may be filled with dangerous programs and cause you damage. When installing software, pay attention to what you agree to download. If you’re going for bundled software, don’t skip any steps. It is entirely up to you whether hackers will successfully compromise your safety or not. To make sure your device remains safe, opt for the Custom/Advanced option. This will allow you to be in control of the installation process. If you’re not the one in charge, it could be cyber crooks. Do the right thing concerning both your privacy and safety. Avoid installing unverified programs, especially when then come bundled. You might notice some unwanted “bonus” infection added to the bundle. In this case, you have to deselect the potential intruder instead of letting it loose. One single wrong click is all it takes to download malware. We’d recommend that you watch out for potential intruders beforehand. Having to remove infections later on is indeed more troublesome. At the least, fighting a parasite is more time-consuming than keeping your PC safe. Another rule of thumb is to delete the spam messages or email-attachments you might receive. Don’t be gullible to open those because you may install malware.

Why is this dangerous?

As mentioned, the Diegocosta.stream pop-ups are deceptive. They attempt to convince you that you have to download a certain plugin. If you do believe the pop-ups, though, you’re in for trouble. Surfing the Internet in general becomes a difficult task, let alone finding what you search for. You get constantly redirected thus landing on potentially unreliable websites. In addition to that, your PC screen is covered with sponsored commercials, product deals and offers. All advertisements could turn out to be corrupted so don’t be gullible. Hackers were never really trying to enhance your online experience. They are only trying to make money by boosting web traffic. To top it all, crooks get access to your private information. Your browsing history, IP addresses, usernames and passwords are being spied on. To prevent privacy harm, you have to take measures. Please follow our detailed manual removal guide down below.
