How to uninstall Borr from the operating system

Also Known As: Borr virus
Type: Trojan
Damage level: Severe

What is Borr?

Borr is the name of a malicious program which can be purchased from hacker forums. The cost is equivalent to $100 for the first month, after which the monthly cost becomes $50. Cyber criminals use Borr to steal various sensitive information, which they can misuse to generate revenue in various ways.

Users who have Borr installed on the operating system are exposed at risk of financial loss, identity theft, problems relating to privacy and other issues. Therefore, if there is any reason to believe that Borr is installed on your computer, it should be removed immediately.

Borr malware

Cyber criminals can use Borr to steal passwords, browser histories, auto-fill data and cookies, system information, credit card details, Jabber, Outlook and Thunderbird clients, VPN applications, wallet.dat files, monitor computing activity and infect systems with other malware.

Borr is a powerful tool that can cause serious damage. Since this malware is capable of stealing auto-fill data and passwords, cyber criminals can use it to hijack the aforementioned clients (Jabber, Microsoft Outlook and Mozilla Thunderbird), and also other accounts.

They can use these to run scam campaigns, deceive other users into installing malicious software (including Borr itself), transfer money and perform other actions. They can also use them to make fraudulent purchases/transactions and generate revenue in other ways.

The same applies to stolen credit card details. Stolen wallet.dat files can be used to access cryptocurrency wallets (private keys) and used to send cryptocurrency to wallets that are managed by cyber criminals. Borr can infect the operating system with other malicious software such as ransomware, Trojans, and other high-risk malware.

This software can also cause serious problems such as data, financial loss, and installation of additional malware. Cyber criminals might use Borr to install a cryptocurrency miner. In this way, they can use the infected machine to mine cryptocurrency, which could lead to higher electricity bills, hardware overheating, system crashes that could cause data loss, and so on.

Furthermore, cyber criminals behind Borr can use the software to monitor screen activity. Therefore, they might gain access to personal information stored in documents (or other files) that victims open, etc. Being a victim of a Borr attack can thus result in serious problems. If this malware is already installed on the operating system, it should be eliminated immediately.

Other examples of malicious software used by cyber criminals who seek to generate by stealing sensitive information and infecting systems with other malware include GrandSteal, Vidar, and Buer Loader

Typically, people who are tricked into installing this malicious software suffer monetary and/or data loss, become victims of identity theft, and experience problems relating to privacy and other serious issues. Note that people often infect systems with this software inadvertently.

How did Borr infiltrate my computer?

In most cases, operating systems become infected with malicious programs through spam email campaigns, Trojans, fake software updaters, unofficial activation ('cracking') tools and dubious file/software download channels and sources.

Cyber criminals attempt to proliferate malware via spam campaigns by sending emails that contain malicious attachments or website links designed to download malicious files. They send emails that contain files such as Microsoft Office, PDF documents, archive files (ZIP, RAR), executable files (.exe) or JavaScript files.

When opened, these files cause installation of malware. Fake software updaters usually infect operating systems by installing malicious software rather than updates/fixes, or by exploiting bugs/flaws outdated software that is installed on the computer. Trojans are malicious programs that proliferate other programs of this kind.

In summary if a system is infected with a Trojan, it is likely to be infected with other malware. Peer-to-peer networks (torrent clients, eMule), free file hosting, freeware download, unofficial websites, third party downloaders, and other similar software download channels are often used to host malicious files.

Cyber criminals upload malicious files that are disguised harmless/regular and hope that someone will download and open them. When opened, the files infect systems with malicious software. Unofficial activation tools supposedly activate licensed software free of charge/bypass paid activation, however, rather than activating any software, they install malware.

How to avoid installation of malware

Files attached to irrelevant emails that are received from suspicious, unknown addresses should not be opened. The same applies to website links within them. Note that these emails are usually disguised as official and important. If there is a reason to doubt that a received email can be trusted,  ignore it.

All files and programs should be downloaded from official and trustworthy websites - none of the channels, sources, and tools mentioned above should be trusted or used. Installed software should be updated with implemented functions and tools that are designed by official software developers.

If installed software is not free and needs to be activated, this should be done properly. Unofficial activation ('cracking') tools can infect computers with malware and it is illegal to use them for activation of any licensed software. To keep your computer safe, have reputable anti-spyware or antivirus software installed and use it to scan for and remove any threats.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Click 'Options' at the top and uncheck 'Hide Empty Locations' and 'Hide Windows Entries' options

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 Combo Cleaner Antivirus for Windows.
