  • system data modified;
  • stolen or deleted data;
  • changed registry keys.

When the file starts utilizing almost 100% of the CPU or using other resources, people start considering virus infection. All this background activity causes system freezes or crashes, issues with graphics or drivers.

Avoid questionable emails and suspicious executables

Using suspicious websites as your software providers or getting programs from the internet via p2p services can lead to malware infiltration and unwanted installations. Also, opening emails from unknown sources, especially if the email contains file attachments, can result in more severe malware infections.

Trojans, malware or even ransomware can spread on the system when you open the infected document. Researchers[4] note that spam email campaigns get more and more advanced because emails often fo straight to your regular email box and contain well-known company or service names as a disguise.

When you open the infected Word or Excel, PDF file malicious macros are triggered, and payload launches in the system. Then direct malware is installed on your computer or malicious script is spreading further on the targeted network. You can avoid this infiltration by installing advanced anti-malware and scanning the system occasionally.

Eliminate KingMiner, associated files, and end all related processes

Remove KingMiner from the system with anti-malware tools like ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes and clean the system further this way. A full system scan using these programs detects all malicious files, programs or potential threats and helps to delete them.

After the automatic KingMiner removal using anti-malware, make sure that no additional processes are running in the background of your computer. You can check this in your Task Manager, then end the process that is suspicious or using high CPU.

You may need to enter the Safe Mode before scanning the system with antivirus program because KingMiner virus is a persistent threat that alters various parts of the system and even adds Windows registry keys to make sure the malicious process is loaded every time your PC is turned on.

How to prevent from getting trojans

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
