How to remove Sn0wsLogger malware from the operating system?

Also Known As: Sn0wsLogger stealer
Type: Trojan
Damage level: Severe

What is Sn0wsLogger?

Sn0wsLogger is a piece of malicious software, which is classified as a stealer. The primary purpose of this type of malware is to steal a variety of sensitive and confidential information. Stealers can have various abilities, enabling them to carry out this purpose. However, in addition to being a severe privacy concern, these malicious programs also pose a threat to device safety.

Typically, stealer-type malware collects information by extracting it from browsers and various other applications. From the former, data of interest includes: browsing activity (URLs visited, pages viewed, search queries typed, etc.), Internet cookies, saved log-in credentials (i.e., IDs, usernames and passwords), credit card details, and so forth.

Similarly, from other types of apps (e.g., messaging platforms, data storage service providers, email clients, etc.), stealers attempt to extract log-in credentials. Keylogging is also a common functionality of information-stealing malware. This feature allows malicious programs to record key-strokes, thereby endangering the privacy of any and all typed information.

Malware of this type may have other functionalities, which can pose additional threats to device/user safety. Log-in credentials are especially sought after by cyber criminals, as they allow them to gain access and control over the corresponding accounts. Emails are of particular interest as they are usually connected with other accounts and services.

Hence, through stolen email accounts, criminals may hijack those associated with them.

To elaborate on how certain accounts can be abused; through ones providing communication services (e.g., emails, messengers, social networking, social media, etc.), cyber criminals can ask contacts/friends for loans and/or proliferate malware (by sharing infectious files) - under the guise of the genuine owner.

Should any confidential/compromising content be found within the affected device and/or data storage/transferring accounts - it can be used for ransom purposes. In other words, criminals can threaten to publicize or sell the material - if they are not paid.

Accounts that directly or indirectly deal with finances and financial information (e.g., banking, digital wallets, online money transferring, e-commerce, etc.) can be used to make fraudulent transactions and/or online purchases. In summary, Sn0wsLogger infections can result in serious privacy issues, financial losses, and identity theft.

Therefore, if it is known/suspected that the Sn0wsLogger stealer (or other malware) has already infected the system - an anti-virus must be used to remove it immediately.

AlfonsoHunterXenon, and Covid are some examples of stealer-type malware. Malicious programs can have a wide variety of heinous functionalities, and these functions can be in different combinations.

Common types/features include (but are not limited to): data encryption and/or screen-locking for ransom purposes (ransomware), download/installation of additional malware, recording/streaming video and/or audio via device's webcam/microphone, use of system resources to mine cryptocurrency (cryptominers), keylogging, information extraction from various browsers and apps, exfiltration of stored content, remote access and control over the infected machine, etc.

Regardless of how malware operates, it poses a serious threat to device integrity and user privacy. Therefore, all system infections must be eliminated without delay.

How did Sn0wsLogger infiltrate my computer?

Malware is distributed through untrustworthy download sources (e.g., unofficial and free file-hosting websites, Peer-to-Peer sharing networks, and other third party downloaders), typically disguised as or bundled with ordinary content.

Illegal activation tools ("cracks") and fake updaters are prime examples of malware-spreaders, which are often obtained from dubious download channels. "Cracking" tools can download/install malware instead of activating licensed products.

Fake updaters cause infections by abusing flaws of outdated programs and/or by installing malicious software rather than the promised updates. Spam campaigns are also commonly employed to proliferate malicious programs. This term defines a mass-scale operation during which thousands of scam emails are sent.

These letters are usually presented as "important", "urgent", "priority" and similar; they may even be disguised as mail from legitimate institutions, organizations, companies, businesses, service providers, and other entities. The deceptive emails contain download links of infectious files and/or the files are simply attached to the letters.

Virulent files can be in various formats (e.g., PDF and Microsoft Office documents, archives, executables, JavaScript, etc.) and when they are opened - the infection process (i.e., malware download/installation) is triggered.

How to avoid installation of malware?

It is highly recommended to only download from official and verified sources. Additionally, all programs must be activated and updated with tools/functions provided by genuine developers. Since illegal activation tools ("cracks") and third party updaters often spread malicious software.

To avoid malware proliferated via spam mail, it is expressly advised against opening suspicious/irrelevant emails - especially any links or attachments found in them. It is paramount to have a reputable anti-virus/anti-spyware suite installed and kept up-to-date.

This software has to be used to perform 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.

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:

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.
