How to protect the computer from Zwer ransomware?

After the ransomware is removed, it is important to prevent similar incidents from happening again. To effectively protect the computer, the user must know how Zwer ransomware was able to infect it. To minimize the possibility of infection, staying away from the common sources of this virus is crucial.

How does ransomware infect your computer?

The method of infecting the computers was found to be similar to that of other common viruses. Ransomware like Zwer is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and Trojan Downloaders.

Once the virus is executed, it immediately infects the system. Then, Zwer ransomware communicates with a remote server so that a unique key can be generated for a specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. In the final stage of the attack, Zwer ransomware demands ransom money in exchange for the decryption tool. To further understand the attack scheme, we have included an infographic below.

What are the essential things to do?

Do a Regular File Back-up - Always backup your data on a separate storage devices such as external hard drives, optical discs, or online backup services.

Keep Your Software Updated - Make sure that you have the latest software updates especially on the operating system. Recent updates often contain vital security patches to help protect the computer against all forms of threats.

Install a Security Program - Protect the computer with effective anti-virus application using efficient real-time scanning. Regularly run a complete scan to check the computer for presence of malware.
