Xfirefox.exe

We want to inform you about a recently found and highly dangerous computer infection that was dubbed Xfirefox.exe. However, this program can go by many names that we will list in this description. You have to remove it from your PC because our analysis has revealed that it can steal your personally identifiable information and, thus, compromise your computer’s security. It can infect your computer secretly, so if you do not have an anti-malware tool, then there is nothing to stop it from compromising your computer’s security. In this short article, we will discuss how this program works, how it is distributed and how you can get rid of it.

Trojans can be distributed in many ways. The developers of this particular Trojan have opted for bundling this application with bad software downloaders. These downloaders are applications featured on shady freeware hosting websites that you must download and install in order to download the application you initially wanted, and you need to download a downloader for each application separately. Thus, It is by no means a universal content downloader. There is no information about it installs Xfirefox.exe, but it is more than likely that injects it into your computer secretly, and you cannot deselect its installation. According to our analysis, Xfirefox.exe can be dropped in %APPDATA% or %APPDATA%\JAVA. As mentioned in the introduction, Xfirefox.exe can also go by other names and they include firefox.exe, Stub1000_1_19_2016.exe and run32dil.exe. So it may try to trick you into thinking that it is Firefox that is running — not some Trojan.

Now, this program can do many things. We have found that it features Firefox Developer Addition that is used to show promoted websites. The sites can include car and audio-related websites that Firefox Developer Addition will open and close at random. Testing has shown that Xfirefox.exe will open to separate Firefox Developer Addition windows on top of the desktop. The list of URLs to which it redirects to are hosted at C:\Windows\SysWow64\prev.dat. Apart from that, this application will create a Point of Execution (PoE) at HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Run that will run this program on each system startup.

However, the primary reason this program is highly malicious is that it can steal your information. Trojans encompass a broad spectrum of malware that do various highly malicious things and stealing information is one of them. We think that this program might feature a keylogger to record your every keystroke and send it back to the developers to they could extract logins and passwords and then steal your accounts such as your Paypal account, for example, and then send all the funds to another account. It might also record your chats and conversations and use them to blackmail you, although this is highly unlikely as it is a time-consuming process that might not pay off. On top of that Xfirefox.exe might just take your personal files and upload them to its remote server. In any case, it is clear as day that you do not want it to show ads or steal your information because that can prove detrimental.

There is no doubt that Xfirefox.exe is a malicious application that can steal your information and also generate advertising revenue by forcefully opening promoted websites that were not checked for safety. This application can compromise your computer’s security significantly. Therefore, we recommend that you remove it using our guide or SpyHunter — our featured antimalware application.
