Babax virus removal guide
What is Babax?
Babax (also known as Osno) is the name of an information stealer targeting login credentials (usernames, emails, passwords) saved on web browsers. Cyber criminals use this malware to steal sensitive information that could be misused to generate revenue. Research shows that Babax infects computers through other machines that are connected to the same network. Also, this stealer is crypted, which means can avoid detection by installed security suites.
As mentioned in the introduction, cyber criminals use this malware with a purpose to steal login credentials. It means that cyber criminals behind it might steal email, social media, banking, file hosting and other accounts, cryptocurrency wallets, and use them to make fraudulent purchases, transactions, steal identities, access personal documents (and files), spread this and other malware (send malspam), trick other people into transferring them money, etc. Also, they could sell all collected information (or other accessed data) to third parties (other cyber criminals). Therefore, victims of Babax attack may suffer monetary loss, lose access to various accounts, become victims of identity theft, experience problems related to online privacy, browsing safety, etc. If a computer is infected with this information stealer, then it should be eliminated from the system as soon as possible. Since Babax spreads through network, its removal prevents other computers connected to the same network from being infected with it as well.

How to avoid installation of malware?
It is not safe to download (or install) any programs or files through third party downloaders, installers, unofficial sites, Peer-to-Peer networks and so forth. The safest option to download files and programs is to use official websites and direct links. Also, it is important to update and/or activate installed programs only with implemented functions or tools that are provided/designed by their official developers. Third party activators, updaters should often are designed by cyber criminals. Besides, it is illegal to activate licensed software with unofficial, third party tools. Furthermore, website links and/or files attached to irrelevant emails that are received from unknown, suspicious addresses should not be opened. It is common that such emails are sent with a purpose to distribute some malicious software. It is worthwhile to mention that such emails often are disguised as important, official. Additionally, it is recommended to regularly scan the operating system with a reputable antivirus or anti-spyware software and always keep it up to date. If you believe that your computer is already infected, we recommend running a scan with Malwarebytes for Windows to automatically eliminate infiltrated malware.

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.
