Backdoor.Kuyama is the nth member of the Trojan horse family. If you are infected with it, you are in for a bad time. Trojans` horrible reputation is absolutely deserved. They are rightfully considered the most dangerous type of cyber infection. That’s why when they hear the word “virus”, most people`s minds go straight to Trojans.

Once the Trojan enters, everything turns upside down. The virus starts messing with your system and making unauthorized changes in your settings. It doesn’t need your permission to do so. It now controls your machine. Backdoor.Kuyama reedits your system registry behind your back as well. It adds and/or removes entries from it, thus causing some of your programs to run poorly. In other cases, your apps fail to work at all. Your computer, in general, becomes incredibly slow and starts do underperform on daily basis. You experience frequent system crashes, reboots, and breakdowns. Getting any work done becomes impossible. There is more, though.

The Trojan affects your online activities too. It hijacks your browsers and causes them to redirect you to shady pages all the time. Whenever you go online, you get interrupted by redirects and countless, suspicious-looking ads. Surfing the web turns into a nightmare. But there is more. Backdoor.Kuyama also serves as a backdoor to other infections. Mostly to ransomware. It disables your anti-virus program and thus opens the gates of your PC to other threat. You are constantly exposed to malware risk. All day, every day.

But like this is not bad enough, Backdoor.Kuyama spies on you. After all, this is a Trojan we are talking about. From the moment it enters, it starts monitoring your every online move. Not only that, but it also collects all the sensitive and personal information about you that it can find. Once it decides it has gathered enough data, it sends it all to the hackers behind it. Then, who knows what they will use your private details for. It won`t be something good, trust us. So, don’t let it go that fat. Either use our removal guide below and remove the Trojan or get an anti-malware app to get the job done. Whichever option you choose, act fact. Delays lead to regrets.

How did you get infected with the Backdoor.Kuyama Trojan? There are many possible scenarios but the most commonly used methods when it comes to Trojans are malicious spam email attachments and corrupted pages (adult pages).

It may easily be a virus and if you click it open, it will enter your PC without you noticing.
