Dexphot virus removal guide

What is Dexphot?

Dexphot is the name of a malicious program that is designed to infect systems with a cryptocurrency miner. It is capable of reinstalling a miner if an installed antivirus suite attempts to remove it. Simply said, cyber criminals use resources of infected systems to mine cryptocurrency which helps them to generate revenue. If there is a reason to believe that a computer is infected with Dexphot (or any other cryptominer), then it should be removed from the system as soon as possible.

Dexphot malware

Dexphot is a quite sophisticated malware that is capable of evading security suites. Research shows that it evades them by using layers of obfuscation, encryption and by randomizing filenames of its installation process. It runs a malicious code directly in memory without saving it on the file system. This malware disguises itself as a legitimate processes by replacing contents of the legitimate processes with a malicious code. If not detected, stopped and removed, then Dexphot runs one of the cryptocurrency miners. It is known that this malware can run XMRig and JCE Miner miners, however, it is possible that it may run other software of this type as well. As we mentioned in the introduction, Dexphot is capable of reinfecting systems if installed security suite attempts to remove it. It runs two monitoring services and three malicious processes, if one the running processes is terminated, then monitoring components terminate other malicious processes and re-infect a system through PowerShell by running a certain command. Also, it is known that those monitors are capable of detecting and terminating launched cmd.exe processes. The main purpose of Dexphot is to install a crypto miner, programs of this type mine cryptocurrency by using system resources such as CPU and GPU. Miners use them to solve mathematical problems, every solved problem is equivalent to a certain fraction of a cryptocurrency coin (i.e., Monero or Bitcoin). The problem is that mining processes often cause high CPU and/or GPU usage, which means systems run slow or do not respond at all. It might cause system crashes, permanent loss of unsaved data, overheat of hardware, and so on. Besides, computers that mine cryptocurrency use more electricity, it means that their users receive higher bills. In order to avoid financial loss or other mentioned problems it is required to remove any installed crypto miner as soon as possible. The same applies to the Dexphot malware.

There are various different cryptocurrency miners, many of them are legitimate. However, even legitimate ones can be used for malicious purposes. Cyber criminals attempt to trick people into installing them in various ways and then generate revenue through their computers. Some examples of methods that cyber criminals use to trick people into installing unwanted software are provided below.

How did Dexphot infiltrate my computer?

Most popular ways to spread malware and other unwanted software is to use spam campaigns, fake software updating tools, unreliable download channels, Trojans and unofficial software activation tools. Spam campaigns are being used to infect systems with unwanted, often malicious programs through attachments that cyber criminals send via email. Typically, they attach files like Microsoft Office or PDF documents, JavaScript files, executable files like .exe, archive files like ZIP, RAR, and so on. If opened, those attachments infect systems with malware (in this case a cryptocurrency miner). Fake software updating tools cause damage when by exploiting flaws, bugs of outdated software or by install malicious software instead of updates. Peer-to-Peer networks like torrent clients, eMule, freeware download or free file hosting pages, third party downloaders, unofficial websites, etc., often contain malicious files that are disguised as legitimate. Cyber criminals upload them with a purpose to trick people into downloading them. If executed/opened, those files install malicious software. Trojans often are designed to cause installation of various high-risk malware. However, Trojans cause chain infections only when people already have their computers infected with them. Unofficial activation tools, if used to bypass activation of licensed software, often infect systems too. Simply said, tools of this type often are designed by cyber criminals who attempt to infect computers with various malware.

How to avoid installation of malware?

Files and/or web links that are attached to irrelevant emails should not be opened. Especially if they are received from unknown addresses. It is worth mentioning that cyber criminals usually disguise their emails as official, important, etc. Software should be downloaded only from official websites and via direct download links. All other sources that we mentioned in the previous paragraph should not be trusted. Furthermore, it is important to update software using tools or implemented functions that are designed by official developers, and not through third party, fake updaters. The same applies to activation of licensed programs and operating systems - they should not be activated using any third party tools, besides, it is illegal to activate software that way. One more important thing is to have a reputable antivirus or anti-spyware software installed and scan the system with it regularly. If you believe that your computer is already infected, we recommend running a scan with Spyhunter 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 Spyhunter for Windows.
