Vobfus can modify the Windows Registry. This database contains settings/options, information and other values concerning software and hardware installed on the Windows Operating System. The program modifies specific registry entries, so that it is launched each time the system starts up.

Other registry entries are modified to prevent display of files that possess "System" and "Hidden" attributes. Through the Windows Registry, this malware disables automatic updates for Windows. It also establishes contact with a remote server, thus allowing cyber criminals to give Vobfus further commands.

The program can cause chain infections as well - Vobfus can download/install additional malware (e.g Trojans, ransomware, cryptominers and other malicious software). In summary, systems infected with this malware can experience multiple infiltration/infections, thereby suffering serious damage.

Stored data can be encrypted or stolen, victims can experience significant financial loss, serious privacy issues, identity theft and various other problems. All malware infections are dangerous to device and user safety. If the system is infected with Vobfus, it is paramount to remove it without delay.

Malicious software has many capabilities including, for example, download/installation of malware (e.g. Legion LoaderGlupteba etc.), information theft (e.g. Predator The ThiefKBOT etc.), remote access (e.g. XtremeShadowTechRAT etc.), data encryption for blackmail/ransom purposes (e.g. KrakenPwndLocker etc.) and many others.

Regardless of how they operate, these programs are designed to generate revenue for the cyber criminals behind them.

How did Vobfus infiltrate my computer?

The main modes of malware proliferation are via spam campaigns, illegal software activation ("cracking") tools, fake updates and untrusted download sources. The term "spam campaign" defines large scale operations during which thousands of deceptive/scam emails are sent.

This mail is usually presented as "official", "priority", "urgent", "important" and similar. The messages are often disguised as being sent from legitimate institutions organizations, companies and services - thereby increasing their chance of success.

Infections originate from dangerous files attached to these emails, or alternatively can have download links to malicious programs. Infectious files can be in various formats, such as archive (RAR, ZIP) and executable (.exe, .run) files, PDF and Microsoft Office documents, JavaScript and so on.

When these dangerous files are executed, run or otherwise opened, the infection process is triggered (i.e., download/installation of malware). Rather than activating licensed products, illegal activation tools ("cracks") can download/install malicious software.

Fake updaters infect systems by exploiting the weaknesses of outdated programs and/or simply by installing malware rather than the promised updates.

Untrustworthy download channels such as unofficial and free file-hosting websites, Peer-to-Peer sharing networks (BitTorrent, eMule, Gnutella, etc.) and other third party downloaders can offer malicious content for download and disguised as legitimate software or bundled (packed) with normal products.

How to avoid installation of malware

Do not open suspicious or irrelevant emails, especially those received from unknown or suspect senders (addresses). Any attachments or links found in dubious messages must never be opened under any circumstances, as doing so can result in various high-risk infections.

You are strongly advised to use only official and verified download channels, as opposed to sharing networks and other third party downloaders. It is also important to activate and update products with tools/functions provided by genuine developers. Do not use illegal activation tools ("cracks") or third party updaters, as they are commonly used to proliferate malicious programs.

To ensure device integrity and user safety, it is crucial to have a reputable anti-virus/anti-spyware suite installed and kept up to date.

Furthermore, use this software to perform regular system scams and removal of detected/potential 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.

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.
