Adver Ransomware: A Complete Guide to Understanding, Removing, and Preventing It

Ransomware continues to be one of the most devastating types of malware that affects users worldwide. Among the various ransomware threats, Adver has recently gained attention due to its ability to encrypt victims’ files and demand a ransom in exchange for decryption. In this article, we’ll explore the Adver ransomware in detail, including its infection methods, how it works, symptoms, and how to remove it from your system. Additionally, we’ll discuss preventive measures to avoid future infections.

What is Adver Ransomware?

Adver is a form of ransomware that encrypts files on an infected computer, rendering them inaccessible without decryption. The ransomware appends the “.adver” extension to the encrypted files, making it easy to identify the affected files. For example, an image like “1.jpg” would become “1.jpg.adver,” and similarly, other types of files such as documents and videos will also get their extensions changed.

Ransomware like Adver is typically spread through malicious email attachments, infected software downloads, or compromised websites. Once executed, Adver starts encrypting files and displays a ransom note that instructs victims on how to pay for the decryption key. However, it is essential to understand that paying the ransom does not guarantee that the attackers will provide the decryption tool.

How Does Adver Ransomware Work?

When Adver infects a computer, it starts by encrypting specific file types on the system. These file types can include images, documents, videos, and other important files, rendering them unusable. Each encrypted file has the “.adver” extension added to it, making it clear that it has been locked by the ransomware.

The ransomware then creates a ransom note named “RECOVERY INFORMATION.txt”, which contains a message for the victim. The note provides instructions on how to recover the files. Typically, the attacker demands payment in cryptocurrency, such as Bitcoin, and provides a contact email address (adver@mailum.com) for communication.

The ransom note will usually include the following key points:

• Instructions for paying the ransom: Victims are often instructed to visit a specific website or use a cryptocurrency wallet address to make the payment.
• Personal ID: Some versions of Adver ransomware may require the victim to provide a unique ID to begin the decryption process.
• Threats of file deletion: The attackers will often threaten to permanently delete the encrypted files if the ransom isn’t paid within a specific timeframe.

Symptoms of Adver Ransomware Infection

After Adver infects your system, you may notice several distinct symptoms:

1. Files are encrypted: The most apparent sign of Adver infection is the alteration of file extensions. Files that were once accessible become unreadable and now have the “.adver” extension attached.
2. Ransom note: Victims will find the “RECOVERY INFORMATION.txt” file on their desktop or within infected directories. This file will contain information on how to pay the ransom and recover the encrypted data.
3. Inability to open files: Since the files are encrypted, you will be unable to open or use them without the decryption key.
4. Strange system behavior: In some cases, the infected computer may run slower than usual or exhibit other unusual behavior, such as increased CPU usage and lag.
5. Ransom demand message: A ransom note will likely appear as a pop-up window or on your desktop, demanding payment to decrypt your files.

How Did Adver Ransomware Infect My Computer?

Adver ransomware, like many other types of malware, is commonly spread through various methods. Some of the most frequent distribution channels for Adver include:

1. Malicious Email Attachments: Cybercriminals often distribute ransomware via phishing emails with infected attachments. These emails may appear to be from legitimate sources, tricking the victim into opening the file.
2. Infected Software Downloads: Downloading pirated software or using crack tools can also lead to ransomware infections. These downloads often contain malware that is executed when you install the software.
3. Compromised Websites and Malicious Ads: Visiting compromised websites or clicking on malicious ads can also trigger a ransomware infection. These websites may exploit vulnerabilities in your browser or operating system to deliver the ransomware payload.
4. USB Drives: Ransomware can also be spread via infected USB drives. Once the drive is connected to the victim’s system, the ransomware is activated.
5. Exploiting System Vulnerabilities: Cybercriminals may exploit unpatched security vulnerabilities in your operating system or other software to deliver ransomware. Keeping your system up to date is crucial to preventing this method of infection.

How to Remove Adver Ransomware

Removing Adver ransomware requires a careful, multi-step approach to ensure that the infection is completely eradicated from your system. Here’s a comprehensive guide to remove the ransomware:

Disconnect from the Internet

To prevent further spread and communication with the attacker, disconnect your device from the internet immediately. This will stop the ransomware from transmitting additional data or instructions.

Boot into Safe Mode

Restart your computer and boot into Safe Mode. This will prevent most malware from running when the system starts.

• For Windows 10/11: Press Shift and click on Restart. Then, navigate to Troubleshoot > Advanced Options > Startup Settings and select Restart. Once the system restarts, press F4 to boot into Safe Mode.

Scan with Anti-Malware Software

Use SpyHunter to scan and remove the Adver ransomware. Ensure that you perform a full system scan to detect any lingering malware.

Manually Remove Ransomware Files (Optional)

In some cases, manual removal of ransomware files may be necessary. This involves locating and deleting suspicious files related to the ransomware, such as executables with unfamiliar names. Make sure to back up any important data before attempting this.

Restore Files from Backup

If you have a recent backup of your files, restore them from the backup once the ransomware has been removed. Be sure to verify that the backup is clean and free from malware.

Use a Ransomware Decryption Tool (If Available)

Currently, there is no free decryption tool available for Adver ransomware. However, keep an eye on reputable security websites, such as No More Ransom, for any future decryptor releases.

Preventive Measures to Avoid Adver Ransomware Infections

To avoid falling victim to Adver ransomware or similar threats in the future, consider these preventive measures:

1. Regularly Back Up Your Files: One of the most important things you can do to protect your data is to regularly back up your files. Use both cloud and offline backups to ensure that your data is safe in case of a ransomware attack.
2. Keep Software and Operating Systems Updated: Ensure that your operating system, browser, and software applications are up to date with the latest security patches. This helps prevent cybercriminals from exploiting known vulnerabilities.
3. Be Cautious of Phishing Emails: Avoid clicking on links or downloading attachments from unknown or suspicious email senders. Always verify the authenticity of the sender before opening attachments.
4. Use a Robust Anti-Malware Program: Install a reliable anti-malware solution and ensure that it is always running with real-time protection enabled.
5. Avoid Pirated Software: Avoid downloading pirated software, cracks, or key generators, as these are common sources of malware infections.
6. Enable File Extensions Visibility: By enabling file extensions in your system settings, you can more easily identify suspicious files that may be used to deliver ransomware.

Conclusion

Adver ransomware is a dangerous threat that can cause significant damage to your files and data. It’s important to be vigilant about the ways this ransomware is spread and take proactive steps to protect your system. Regularly backing up your files, keeping your software updated, and using robust security tools are essential in preventing future ransomware infections.
