The versatile nature of Trojan horse infections

A common trait that most Trojan horse viruses tend to have is a versatile toolset that allows them to execute a big number of malicious processes aimed at different targets. Therefore, a Trojan may be tasked with attacking your personal data or corrupting essential system files but also spying on you, loading more malicious programs on the computer (spyware, ransomware, rootkits, etc.), controlling different system processes and so on and so forth. Oftentimes, the damage that is being caused remains unnoticed for extended periods of time which makes it really difficult to spot Trojans like Denonia, Bloom.exe, Browser Assistant etc. However, since you are on this page, reading this article, you are already a step ahead and have a chance to prevent the infection from further messing with your system.

Future system security is essential!

Hopefully, our guide will allow you to take care of the Denonia-related issue without any major setbacks or complications. In case the guide is not enough, we advise you to use the suggested removal tool as it is another great option of handling this type of malware. However, you need to understand that the only truly effective way of dealing with a Trojan is not allowing it to enter your computer.

That is why you should remember to stay away from any web location or piece of content that doesn’t look like it can be trusted. This includes (but is not limited to) unknown sites or sites with a bad reputation, adult sites, sites that have a lot of ads on their pages and also any form of spam messages, questionable-looking web ads or pirated/illegally distributed pieces of software. If you run into anything like that, be sure to stay away from it in order to keep your computer protected. Also, know that good antivirus programs shouldn’t be underestimated as a precaution against any type of malware, so be sure that you get one if you don’t have such a program at the moment.

    After you open their folder, end the processes that are infected, then delete their folders.

    Hold together the Start Key and R. Type appwiz.cpl –> OK.



    You are now in the Control Panel. Look for suspicious entries. Uninstall it/them. If you see a screen like this when you click Uninstall, choose NO:





    Type msconfig in the search field and hit enter. A window will pop-up:



    Startup —> Uncheck entries that have “Unknown” as Manufacturer or otherwise look suspicious.

    • Remember this step – if you have reason to believe a bigger threat (like ransomware) is on your PC, check everything here.

    Hold the Start Key and R –  copy + paste the following and click OK:

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

    A new file will open. If you are hacked, there will be a bunch of other IPs connected to you at the bottom. Look at the image below:

    Type Regedit in the windows search field and press Enter.

    Once inside, press CTRL and F together and type the virus’s Name. Right click and delete any entries you find with a similar name. If they don’t show up this way, go manually to these directories and delete/uninstall them:

    • HKEY_CURRENT_USER—-Software—–Random Directory. It could be any one of them – ask us if you can’t discern which ones are malicious.
      HKEY_CURRENT_USER—-Software—Microsoft—-Windows—CurrentVersion—Run– Random
      HKEY_CURRENT_USER—-Software—Microsoft—Internet Explorer—-Main—- Random

    If the guide doesn’t help, download the anti-virus program we recommended or try our free online virus scanner. Also, you can always ask us in the comments for help!
