Retefe virus removal guide
What is Retefe?
Once executed, the script terminates all browser processes and assigns certain proxy settings to a Tor website. In addition, the script installs a malicious root certificate. During the process, a security warning message appears asking the user to confirm installation of pops up, however, this immediately disappears, since the running script executes another PowerShell script, which mimics the user clicking "Yes" (agreeing to install). Note that Retefe gathers details of various bank accounts and checks which websites the visitor is using. There are several variants of Retefe and they are designed to target different countries. For example, the variant that targets the United Kingdom checks the top-level domain of each visited website. If the domain is ".com" or ".co.uk", the website is loaded through the aforementioned proxy. Bear in mind that, since a malicious root certificate has been installed, cyber criminals are able to issue a certificate for any visited website. This is done to create fake HTTPS certificates. Each time a banking login page is visited, the user is redirected to a fake login page, which appears virtually identical to the original. Criminals do this in an attempt to give the impression of legitimacy and trick users into entering their account credentials and various sensitive data. Once entered, all details are saved to a remote server. In this way, cyber criminals gain access to victims' bank accounts. The presence of this virus can lead to significant issues. Firstly, hijacked accounts can be used to transfer money, make online purchases, etc. Thus, victims can lose savings, wages, etc. In addition, the details can be used to confirm identity online - in this case, cyber criminals might cause privacy issues by stealing identities. If you have even the slightest suspicion that Retefe (or another similar trojan) is present, immediately scan your computer with a reputable anti-virus/anti-spyware suite and eliminate all detected threats.

How to avoid installation of malware?
To prevent this situation, be very cautious when browsing the internet. Think twice before opening email attachments. If the attached file/link seems irrelevant or the email is sent from a suspicious/unrecognizable email address, it should not be opened. Bear in mind that criminals often abuse users' curiosity by sending deceptive emails containing messages such as "you have won a lottery", "you have received a package", and so on. Do not fall for these tricks. In addition, keep the operating system (and installed software) up-to-date. To achieve this, however, use implemented functions or tools provided by the official developer. Also have a reputable anti-virus/anti-spyware suite installed and running - these tools can detect and eliminate malware before any damage is done. The main reasons for computer infections are poor knowledge and careless behavior - the key to safety is caution. If you believe that your computer is already infected, we recommend running a scan with Spyhunter for Windows to automatically eliminate infiltrated malware.

Check 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".
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.
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.
