Ramnit virus removal guide

What is Ramnit?

Ramnit is a family of malware-distribution trojans. Depending on particular variants, anti-virus suites can detect Ramnit as "Win32/Ramnit.A" or "Win32/Ramnit.B". These viruses infiltrate systems without users' consent and open "backdoors" for other malware to infiltrate the system. Therefore, its presence typically leads to further computer infections.

Ramnit malware

Ramnit is capable of injecting malicious code into ".dll", ".exe" and ".HTML" files. Note that Ramnit infects files that are already stored on the computer, and so any existing files are corrupted. Once opened, infected files execute code that stealthily downloads and installs malware onto the system. Ramnit is part of an old trojan family. During its most active period it was used to proliferate viruses (e.g., AZORult). Therefore, the effect of Ramnit's presence might vary. In most cases, these sophisticated tools are used to proliferate information-stealing trojans and ransomware. Information stealers record personal information (e.g., keystrokes, saved logins/passwords, banking information, etc.) and save it to a remote server. Ransomware-type viruses encrypt data and lock computer screens to blackmail victims. In any case, infiltration of Ramnit might lead to serious privacy issues (or even identity theft), and significant financial and data loss. Most reputable anti-virus/anti-spyware suites are capable of detecting and eliminating Ramnit malware (and other viruses proliferated using this tool). Unfortunately, it might be impossible to restore affected files to their previous states. Therefore, if your anti-virus suite detects ".dll", ".exe", or ".HTML" files as malicious, we strongly to recommend that you permanently delete them. Viruses such as Ramnit present a strong case for maintaining regular data backups.

As mentioned above, Ramnit is used to proliferate a number of viruses. These viruses have different developers and their behavior may also differ accordingly (some encrypt data, others steal information, cause further chain infections, etc.), however, all pose a direct threat to your privacy and computer/data safety. Therefore, eliminating all viruses on the system is paramount.

How did Ramnit infiltrate my computer?

Ramnit itself is distributed in a number of ways, including fake 'tech support' scams, spam email campaigns, and RIG Exploit Kit. Fake tech support scams claim that the system is damaged in certain ways (e.g., infected, missing files, etc.) and encourages users to download tools that will supposedly resolve issues. In fact, the issues do not exist and users end up infecting their computers. Spam campaigns proliferate malicious attachments (e.g., JavaScript files, Microsoft Office documents, and so on) that, once opened, stealthily download and install malware onto the system. RIG EK infects computers by exploiting application bugs/flaws.

How to avoid installation of malware?

Lack of knowledge and careless behavior are the main reasons for computer infections. The key to safety is caution. Therefore, pay close attention when browsing the Internet. Remember that no website/browser is capable of detecting viruses on your computer. Therefore, all errors displayed on the Internet are fake and should be ignored. Think twice before opening email attachments. If a received file is irrelevant or the sender seem suspicious, never open the file. Have a reputable anti-virus/anti-spyware suite installed and running, since these tools can detect and eliminate viruses before they do any damage. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

locate the malware file you want to remove

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

searching for malware file on your computer

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs. These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. To keep your computer safe, install the latest operating system updates and use antivirus software.

To be sure your computer is free of malware infections, we recommend scanning it with Spyhunter for Windows.
