CryptBot virus removal guide
What is CryptBot?
CryptBot is a malicious software that is classified as a Trojan, it is designed to steal passwords. It infects systems through the installation setup of a fake VPN program, it gets installed with another trojan-type malware called Vidar. Both trojans are designed to steal saved browser credentials and other information. These malicious programs can cause quite serious problems. Therefore, they should be uninstalled as soon as possible.
Once a fake VPN client called Inter VPN is downloaded, installed and executed, it infects a system with CryptBot and Vidar. It does it by using a AutoHotKey script which downloads executables of both CryptBot and Vidar from the bitbucket[.]org website (they could be downloaded from other sites as well). As we mentioned in the introduction, these malicious programs are designed to steal sensitive, confidential information. They can steal logins and passwords that are saved on browsers, cookies, cryptocurrency wallets, text files, take screenshots of a desktop, and so on. Cyber criminals could use stolen credentials to steal banking accounts, email and messaging clients, etc. They could misuse them to make fraudulent transactions, purchases, spread various malware, trick other people into sending them money, and so on. Stolen cryptocurrency wallets could be used to make transactions into wallets of cyber criminals, which means victims might lose a lot of money. Accessed text files, if contain sensitive details, might be misuses to generate revenue in similar ways as well. Having a system infected with such Trojans can lead to serious problems, for example, monetary loss, identity theft, various privacy issues, and so on. It is important to mention that CryptBot installs a legitimate VPN client (VPN Pro) so that victims would not suspect that two malicious programs are running in the background and stealing sensitive details.

How to avoid installation of malware?
It can be avoided by not downloading files and programs from unofficial websites, through third party downloaders and other tools that we mentioned in the previous paragraph. The safest way to download it is by using official websites and direct links. It is also important to update installed software via implemented functions or tools that are designed by official software developers and not some third party updaters. Attachments (and web links) that are presented in irrelevant emails that are received from unknown, suspicious addresses should not be opened. Also, no third party programs should be trusted to bypass activation of licensed software. It is not legal to use such tools and they often infect computers with malware. And finally, operating systems should be regularly scanned with a reputable anti-spyware or antivirus software and all detected threats removed as soon as possible. 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 is a complicated task - usually it is best to allow antivirus or anti-malware programs to do this automatically. To remove this malware we recommend using Spyhunter for Windows. If you wish to remove malware manually, the first step is to identify the name of the malware that you are trying to remove. Here is an example of a suspicious program running on a user's computer:
If you checked the list of programs running on your computer, for example, using task manager, and identified a program that looks suspicious, you should continue with these steps:
Download a program called Autoruns. This program shows auto-start applications, Registry, and file system locations:
Restart your computer into Safe Mode:

Extract the downloaded archive and run the Autoruns.exe file.
In the Autoruns application, click "Options" at the top and uncheck "Hide Empty Locations" and "Hide Windows Entries" options. After this procedure, click the "Refresh" icon.
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.
