How to remove ProstoClipper malware from the operating system

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

What is ProstoClipper malware?

ProstoClipper (ПростоКлиппер or Клиппер) is malicious software. This malware targets cryptocurrency wallets (cryptowallets) and is compatible with Windows Vista, 7, 8, 8.1 and 10 OS (Operating System) versions. ProstoClipper has certain anti-detection capabilities such as hiding its presence from Windows Task Manager (i.e. its process name does not appear in Task Manager).

ProstoClipper infections can lead to significant financial loss and you are strongly advised to remove this malicious program immediately.

ProstoClipper can obfuscate its presence, which hinders detection. In addition, this malware is 'lightweight' at 50 KB and does not put a strain on system resources - this increases its chances of remaining hidden and avoiding user suspicion (which can prompt unscheduled system scans and other similar user-initiated involvement).

Once a system is successfully infected with ProstoClipper and users attempt to make transactions with certain cryptocurrencies, the malware replaces the cryptowallet addresses entered to those held by the cyber criminals using ProstoClipper. Additionally, the modified cryptocurrency wallet addresses are encrypted.

Furthermore, this malicious program can send status reports to the criminals via Telegram messenger. These reports are sent When ProstoClipper is run and following each successful cryptowallet address swap/replacement. To summarize, ProstoClipper infections can result in financial loss and other potentially serious issues.

If it is suspected/known that ProstoClipper (or other malware) has already infected the system, use anti-virus software to eliminate it without delay.

TaurusSoranoOski and ProstoStealer are some examples of other malicious programs that target cryptocurrency wallets, however, they can also target different information and/or have additional functionality.

Data of interest typically includes banking information, browsing activity, account usernames and passwords (e.g. log-in credentials of emails, social networking, social media, messengers, e-commerce, online money transfer, financial accounts, etc.), content stored on an infected system, and so on.

Regardless of how malware operates, it can cause serious issues and endanger device and user safety. Therefore, it is crucial to remove such infectious immediately upon detection.

How did ProstoClipper infiltrate my computer?

The ProstoClipper malicious program is offered for sale by developers, and hence the methods used to distribute it depend on the cyber criminals' modus operandi. In general, malware is mainly proliferated via Trojans, spam campaigns, illegal activation tools ("cracks"), bogus updaters and dubious download channels.

Trojans are malicious programs with various functionalities that can include the capability to cause chain infections (i.e. download/install additional malware). Deceptive/Scam emails are sent by the thousand, during large scale operations called "spam campaigns".

The messages contain downloads links of infectious files and/or the files are attached to the mail. Infectious files can be in a wide variety of formats (e.g. Microsoft Office and PDF documents, archive and executable files, JavaScript, etc.). When they are executed, run or otherwise opened, the infection process/chain starts.

"Cracking" tools can download/install malicious software rather than activating licensed products. Fake updaters cause infections by abusing flaws of outdated products and/or simply installing malware, rather than the promised updates.

Untrusted download sources 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 programs for downloading, disguised as or bundled with normal content.

How to avoid installation of malware

Do not open suspect or irrelevant emails, especially those with any attachments or links present in them, as doing so can result in high-risk infection. Use only official and verified download channels. It is also important to activate and update products with tools/functions provided by legitimate developers.

Illegal activation tools ("cracks") and third party updaters must not be used, as they often proliferate malware. To protect system health and user safety, have a reputable anti-virus/anti-spyware suite installed. Use this software (which must be kept updated) for regular system scans and to remove 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.

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.
