XTMEM virus removal guide
What is the XTMEM stealer?
XTMEM is malicious software, classified as a stealer. As the classification suggests, this type of malware steals information. Stealers have a wide range of dangerous capabilities, which can lead to likewise varied issues for users of infected devices. XTMEM poses a significant threat to device and user safety and, as such, must be removed from systems immediately upon detection.
Malicious programs within the stealer classification can target a broad range of information/content and have many different functions, enabling them to successfully carry out data theft. Some stealers can exfiltrate files stored anywhere on the infected system, whilst others can download them only from specific locations (e.g. the desktop). This malware typically targets certain browsers and other applications. Information of interest from these apps includes (but is not limited to) account log-in credentials (e.g. IDs, usernames and passwords), browsing and search engine histories, browser cookies, auto-fills, etc. It is possible for stealers to have keylogging capabilities. I.e., they might be able to record key strokes. Malicious software capable of keylogging poses a threat to the privacy of all typed information. If cyber criminals obtain particularly sensitive or compromising content from the device and/or from online data storage accounts, it can be held for ransom. Hijacked communication accounts (e.g. emails, social media, social networking and various other communication/messaging accounts) can be misused to proliferate malware (by sharing infectious files) and/or to ask contacts/friends for loans - all under the guise of the genuine owner. Accounts that directly deal with and/or store financial information, such as banking account or credit card details (e.g. online banking and money transfers, e-commerce and other similar accounts), can be used to make fraudulent transactions and/or online purchases. To summarize, XTMEM infections can lead to financial loss, serious privacy issues and identity theft. Therefore, if it is suspected or known that the XTMEM stealer (or other malware) has already infected the system, use anti-virus software to eliminate it without delay.

Zeromax, Echelon, and Mist are examples of other stealer-type malicious programs. As mentioned, this malicious software can have various capabilities/features. While the primary functionality of stealers is data theft, they might also have spying capabilities (e.g. taking screenshots, recording audio and/or video via integrated/connected microphones and cameras, etc.), and cause download/installation of additional malware, and so on. Regardless of how malicious software operates, the purpose is identical: to generate profit for the cyber criminals using it.

How to avoid installation of malware
You are strongly advised against opening suspect and/or irrelevant emails, especially those received from unknown/suspicious addresses. Any attachments or links found in such messages must never be opened, as this can result in a serious system infection. Use official and verified download channels. It is also important to activate/update products with tools or functions provided by legitimate developers. Illegal activation tools ("cracks") and third party updaters must not be used, as they often proliferate malware. To protect device integrity and user safety, it is crucial to have reputable anti-virus/anti-spyware installed and updated. This software must be used to perform regular system scans and to remove detected threats/issues. 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".
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.
