MirrorBlast is a software threat of the Trojan Horse category that can silently enter any system, and operate from within it without getting noticed by the user. A reliable antivirus can typically spot most Trojans, but MirrorBlast is a brand new infection of this category, and it is likely that many antivirus solutions are yet to have it added to their databases.
This significantly decreases the chances of spotting the threat if your antivirus is outdated, and doesn’t have MirrorBlast in its database. Additionally, most Trojans do not show many visible symptoms, making it even harder to spot them. Occasionally, some threats of this type may cause your computer to suddenly restart, to experience BSOD crashes, and to get various errors, but it’s also possible that none of those infection signs are present if your machine gets infected. Here, we will explain to you some of the characteristics of threats like MirrorBlast, and we will attempt to help you remove this Trojan from your computer if the machine has already been infected.
The typical characteristics of a Trojan Horse program
If you know, or at least suspect that the insidious MirrorBlast has managed to enter your computer, this brings you a step closer to removing the malware. As we said above, threats of this type (Great Discover, Walliant) are really difficult to spot on time, especially if they are newer ones like MirrorBlast. The fact that you know that there may be an infection in your computer is actually good news – many users have Trojans in their systems for weeks, or months, and only find out about them when it’s too late to do anything. You, on the other hand, can now take matters into your own hands, and eliminate the threat by finding its files, processes, and Registry keys, and removing them. There, however, is a problem with that, namely the fact that those elements are likely to be disguised. For instance, the files of the Trojan may be located in system folders, and its processes may have the same names as legitimate OS ones. This significantly increases the chances of deleting some files or ending some processes that are actually inherent to your system, and should not be touched. This, in turn, could lead to many serious issues with your system, and make the situation even worse. The guide below offers instructions on how to locate the malware elements, and delete them, but you must be really careful. If you have any doubts about whether something should be removed or not, contact us in the comments section, or use the automatic removal tool that’s linked below (it can find the malware data for you, and help you remove it).
A Trojan can cause harm in different ways
Spying on your activities, corrupting your data, extracting sensitive personal information, and loading Ransomware cryptoviruses in your machine are only a small number of all the things that Trojan infections may be capable of. The exact goal of MirrorBlast in particular is unknown for the time being, but you should nevertheless make sure to remove this threat from your computer as soon as you are able to in order to avoid all kinds of unforeseen consequences.

MirrorBlast is a stealthy threat that is known to invade different system locations by secretly adding malicious components in them. Finding and removing these components can be a challenging task that requires all your attention because there may be numerous processes and apps related to the Trojan. Therefore, if you want to remove MirrorBlast successfully, one of the very first things that you need to do is check the programs that have been installed on your PC for suspcious-looking programs that have been added recently and uninstall them if you believe they are part of the infection.
The easiest way to do that is to use the Windows and R keyboard key combination and type appwiz.cpl in the Run window:
After that, click OK and this will open the following location: Control Panel>>> Programs and Features >>>Uninstall a Program.
If you spot a program or programs that you can’t remember installing, or in case you have recently installed a program from a questionable source that you believe could be related to the infection, research it online to learn more about the program and then, based on the information that you find, decide if you need to Uninstall it.
If you see a warning window like the one below when you click Uninstall, choose NO and complete the steps from the uninstallation process. Also, pay attention to every checkmark or additional components that might have been installed along with it and select to uninstall them too.
If MirrorBlast keeps messing with your system after you uninstall all programs that you think are dangerous from the computer, then you need to check a few other system locations where the Trojan might have added malicious components and remove anything dangerous that you find there. To do that, please follow the instructions in the advanced MirrorBlast removal guide below.
There will be multiple system reboots during the removal of MirrorBlast. Therefore, before you do anything else, it might be a good idea to Bookmark this page with removal instruction in your browser, so you can easily get back to them with one click and continue from where you left.
Also, it is recommended to restart the infected computer in Safe Mode to limit the activity of the Trojan’s malicious processes as much as possible and run only the most basic system-related processes.
WARNING! READ CAREFULLY BEFORE PROCEEDING!
Use CTRL + SHIFT + ESC as a key combination and start the Task Manager. Look at the running processes in the Processes Tab.
Keep in mind that the Trojan may camouflage its malicious activities under different names. Therefore, the best way to determine if a specific process is dangerous is to right-click on it and open its File Location folder:
Then, with the help of a powerful malware scanner, like the one below, scan all the files related to the process:Shortcode
Immediately end the process (right-click on the process>End Process) if danger is found in the file and delete their File Location folder.
Take your time to carefully check every process in the Task Manager that looks suspicious, or you think might be linked to the Trojan, until you are sure that there is nothing malicious that is running.
To facilitate their malicious activities, many Trojans tend to make changes in system files without notice. The Hosts file of your computer is one of the files that could be altered. To check it for unauthorized changes, first press the Windows and R keyboard keys at the same time and paste the line below in the Run box that you will see:
After that, press Enter from the keyboard and search the text of the Hosts file for Localhost. In case MirrorBlast has made changes in the file, this is where these changes are most likely to be seen. A compromised computer may have a number of questionable-looking IP addresses under Localhost:
If you find such IPs in your Hosts file, please, copy them and drop us a comment below this post, so we can check them and advise you on what your next actions should be.
A number of Trojan-related activities may start as soon as the system reboots. This is typically possible thanks to added malicious Startup Items in System Configuration. To check if MirrorBlast has added such malicious items in the configurations of your system, type msconfig in the search field of the Start menu and press Enter.
When the System Configuration window opens, click on Startup and search for anything suspicious. If you find a Startup Item that you are sure is related to MirrorBlast, remove its checkmark and click OK to save your settings.
The most difficult place to search for Trojan traces and malicious entries is the Registry of your system. Everyone knows that changes in the Registry may seriously affect the stability and the normal operation of the OS. Therefore, you have to be extra careful in this step or use the help of a trusted malware removal tool to clean the Registry and deal with MirrorBlast successfully.
If you want to do that manually, anyways, type Regedit in the Start menu search field and press Enter.
Next, inside the Registry Editor app, press CTRL and F together to open a Find dialog box. Write the name of the Trojan in it and start a search in the Registry.
If threats with the name of the Trojan are found during the search, right-click on them to delete them.
When no more entries are found with the Find box, use the left panel to manually navigate to the following directories:
- HKEY_CURRENT_USER-Software-Random Directory
- HKEY_CURRENT_USER-Software-Microsoft-Internet Explorer-Main-Random
Check each of them for any random entries (folders and files with unusually long names, containing random characters, etc.) and if you find anything suspicious, you should consider deleting it as it might be linked to MirrorBlast. Be careful what you remove though, because, as we mentioned above, deleting legitimate Registry files instead of the malicious ones may cause more harm than good.
