Bloom.exe is a recently-discovered malware program recognized as a Trojan Horse that can take over most systems without symptoms and acquire Administrative privileges. Bloom.exe often gets delivered to its victims’ computers with the help of pirated downloadables and clickbait adverts.

The Bloom.exe virus can be very sneaky and can try to mimic normal system files and processes.

Bloom.exe is a creation of anonymous hackers who have recently been targeting different computers all across the Internet. The new infection operates as a Trojan Horse and can secretly sneak inside the operating system of any computer without showing any visible symptoms. As per the information that we have, Bloom.exe is capable of different malicious activities, which means that it can pose a serious risk to the machine if not removed on time.

The criminals who control the infection use advanced and stealthy methods of distribution for their malicious program such as social engineering and malvertising in order to infect as many people as possible. That’s why the chances of accidentally coming across a transmitter of Bloom.exe are quite high, especially if you frequently browse to insecure web locations or click on sketchy pop-ups and ads.

What is Bloom.exe?

Like most Trojans, the Bloom.exe virus may be found inside spam messages, malicious email attachments, infected links, fake ads, phishing websites, compromised software installers, pirated content, torrents, cracked programs and many other seemingly-harmless carriers. Unfortunately, you may not realize when and how the Bloom.exe virus may sneak inside your computer because it doesn’t typically show any symptoms and also because it purposefully hides its traces once it gets inside the system.

The effects of its attack may also take some time to become apparent which is why it is so important to have reliable antivirus software installed on the computer which can detect and remove the infection on time.

If you don’t have a trusted security tool or your antivirus program cannot deal with Bloom.exe effectively, below you will find a professional removal tool and a manual removal guide which may be invaluable in the fight against this nasty Trojan Horse. Like most of the representatives of this malware family, this threat can also be very sneaky and can try to mimic normal system files and processes in order to prevent its detection. That’s why it is important to scan every location in your system for hidden malware and carefully and correctly navigate to the infected files that need to be removed.

If not eliminated, Bloom.exe can cause serious damage to the OS by modifying and replacing vital system files, corrupting software and also by replacing important processes and services with such of its own. Inserting other viruses such as Ransomware or Spyware and stealing personal information, passwords and banking details are more possible activities that this malware may be programmed to carry out. Another thing some Trojans do is they block the protection provided by the antivirus program while creating security holes in the background.

The most challenging thing about dealing with a Trojan like Bloom.exe or RegHost, however, is to correctly locate it in order to remove all of its malicious components. Usually, this malware tends to spread in different system locations and tries to trick the users and the security software so that it can continue with its criminal agenda without being interrupted. That’s why, in most of the cases, the victims may need the help of a professional system scanner or a combination of a scanner and a manual removal guide in order to navigate to the malicious files and safely delete them.

Remove Bloom.exe Virus

It is very important to get rid of Trojans like Bloom.exe as soon as possible. Here are some quick instructions that we think you should try before you read the guide below:

1. Go to the Windows Start button and click on it.

2. Then, go to Control Panel and click on Programs and Features. Click on Uninstall a Program.

3. As soon as you get there, look very carefully for Bloom.exe and then uninstall the app along with all components that it has added to the system.

4. If you find any other programs that you don’t remember installing on your own, get rid of them as well.

It’s important to keep in mind that even if you finish the steps above, it doesn’t mean that Bloom.exe is completely gone from your computer. Trojans can hide in many places on your system, so to get the best results, we recommend that you follow the detailed removal guide below.


Make sure you bookmark this page so that you don’t lose it if you have to close your browser during some of the steps.

Next, we want you to restart your computer in Safe Mode (you can get the instructions from the active link). This will eventually make it easier for you to find the Trojan on your computer and limit the processes and apps running on your computer down to the most important ones.

In step one, you made preparation for the instructions that follow. Now, go to the Windows Task Manager to see what is going on in the background of your system. CTRL + SHIFT + ESC is one way to open it quickly. Tap on the Processes Tab as soon as the window opens. Take a close look at each process that is shown there.

If you isolate a process that looks suspicious or is run by Bloom.exe, right-click on it. Choose Open File Location from the pop-up menu that comes up next.


Next, drag and drop the files in the free virus scanner and run a scan:

Each file will be scanned with up to 64 antivirus programs to ensure maximum accuracy
This scanner is free and will always remain free for our website's users.
This file is not matched with any known malware in the database. You can either do a full real-time scan of the file or skip it to upload a new file. Doing a full scan with 64 antivirus programs can take up to 3-4 minutes per file.

    This scanner is based on VirusTotal's API. By submitting data to it, you agree to their Terms of Service and Privacy Policy, and to the sharing of your sample submission with the security community. Please do not submit files with personal information if you do not want them to be shared.

    The scan should not take very long, so just wait for it to complete. Afterward, if the scanned files are found to be malicious, go back to the Processes tab, end the processes that are suspicious, and delete the folders that contain the infected files from their File Location.


    Then, go to the Control Panel and look for things that have been installed by Bloom.exe there. To open the Control Panel quickly, you can press the Windows and R keys on your keyboard at the same time. Type appwiz.cpl in the Run box that appears on the screen and hit Enter. 



    When the Control Panel window comes up, look for suspicious and Bloom.exe-related programs in the list and uninstall them. You might get a pop-up message like the one shown below when you try to remove a specific program. Make sure that you choose NO and then go on with the process of uninstalling the app.




    Trojans like Bloom.exe may install some helper components in the system’s start up. This way, they can run as soon as the computer starts. To get rid of these startup items, type “msconfig” in the Windows search field, and then press Enter. 


    If you spot items on the Startup tab that don’t seem to be connected with your system or the apps that you trust, you can remove the checkmark for them to disable them. Pay attention to any entries that look suspicious or have an “Unknown” manufacturer. However, please do not uncheck startup items that belong to legitimate programs and processes, as this may affect the normal operation of your OS.

    • Important! They may help other malware get into the computer. Check your computer to see if it has been hacked or if it has been taken over by a threat like ransomware.

    Press the Windows and R keys at the same time to open a Run box. Then, type this into the Run box:

    notepad %windir%/system32/Drivers/etc/hosts

    When you click OK, you should see a simple text file called Hosts on your screen. It should look like this:

    hosts_opt (1)


    Localhost can be found in the file by scrolling down. Once you find it, check to see if there are any suspicious IPs below, just like those on the sample image above. Drop us a comment if you find something unusual, as this could be a sign that your computer has been hacked. If everything looks okay to you, just close the file and proceed to the next step.


    Last but not least, the Trojan must be removed from your Registry along with all of its files. To do this, type Regedit in the search field on your computer and press Enter. The Registry Editor will open right away.

    As soon as you get there, press the CTRL and F keys at the same time. A Find box will show up on the screen. To search for the Trojan, type its name in the Find box’s search field. Then, start a search in the Registry. If the Find function finds entries with that name, you can right-click on them to delete them.

    After there are no more entries with that name, go to the directories below one by one and carefully search for Trojan-related items that need to be removed:

    • HKEY_CURRENT_USER—-Software—–Random Directory. 
    • HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
    • HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    As a last resort, if the Trojan is persistent and doesn’t want to get removed manually, use the professional removal tool linked on this page to look for hidden Bloom.exe files on your computer. You can also use the free online virus scanner to scan specific files or ask us anything in the comments below, and we’ll do our best to help you.

    • I had found bloom.exe in my details tab in the task manager bar today. Is there anyway I could call one of y’all on discord? I’m scared of permanently damaging my computer by deleting something that I think is malware but actually isn’t. If you have time and decide to help me I thank you. If y’all don’t have enough time and decide not to that’s ok as well. Thanks for the step-by-step guide, I hope it’ll help me!

        • Hey Brandon I downloaded the 15 day free trial and it did remove some items but the main problem is still consisting. Google chrome opens up without me clicking on it and no question that is the virus. I have done everything I can to remove it. The spy hunter says everything is fine but that is definitely not the case as the malware continues to pop up.

          • Hi Robert,
            i would suggest you write the Customer Support of SpyHunter. You will create a ticket with your personal issue and they will help you resolve it.

    • Hey! Found bloom on my computer and im using SpyHunter to remove it, is it okay if I just go into the files and delete it completely?

      Or is there some other steps im supposed to take because this feels alot easier than it should.
