dasHost Virus
The dasHost virus can exploit any existing system vulnerabilities and create new ones

Unfortunately, the carriers of dasHost are numerous and the chance of getting compromised by this malware is quite high, especially if you are not careful while browsing the web. The threat is widely distributed all across the Internet and usually infiltrates the computers when the users interact with the malicious payload, which can be packed with third-party software installers, different social media shares, spam email attachments, ads, intriguing links and more. dasHost is a multipurpose tool for file corruption, destruction, theft, espionage and more.

Is the dasHost.exe file a virus?

No, it is not, but If dasHost.exe is located in a subfolder of “C:\Program Files”, or “C:\Users\\YOUR_USERNAME”, “C:\Documents and Settings\YOUR_USERNAME”, or type %HOMEPATH% in the Explorer address bar, the security rating is extremely dangerous. As such dasHost is a nasty Trojan infection created by criminal hackers, the purpose of which is to infect as many computers as possible and cause various issues in their system. Like most of the representatives of the Trojan horse family, dasHost can exploit any existing system vulnerabilities and create new ones which can be used by other malware such as ransomware, rootkits or spyware

Therefore, it is very difficult to predict what the consequences of its attack could be. The criminals who are in control of the malware may decide to use it to destroy your PC system by deleting important system files and personal data or by creating security holes which can further weaken the OS. They may also be interested in stealing sensitive information such as passwords or banking details, which can later be used for theft of the user’s online identity or of money from their bank accounts.

It is also possible for the crooks to establish full remote control over the infected computer and to exploit its resources for their purposes, thus way causing sluggishness when you want to launch your programs. Unfortunately, it is very difficult to detect those harmful activities because dasHost hardly ever shows any symptoms that could give it away. That’s why it is very important to detect the malware and remove it in time, before it manages to damage your system beyond repair.

What is the best way to remove dasHost?

Trojans are very stealthy and very challenging computer threats. That’s why if you want to deal with them effectively, you need to be very careful and use professional malware-removal tools or go through various removal steps. The reason is, these threats, like Altruistics, tend to hide deep in the system and oftentimes may mimic some important files in order to trick the users and prevent them from detecting and deleting them. Locating the harmful code and having it removed, however, may require some computer skills.

That’s why, if you are not experienced enough or don’t know what exactly you have to delete, it is not advisable to experiment because you may delete something related to your OS by mistake. In order to avoid this, we suggest you use the instructions in the removal guide above and also scan the system with the attached removal tool. It is very important to remove dasHost and its core files properly, otherwise, the Trojan may continue to create issues inside the computer and to serve the needs of its criminal creators without your knowledge.

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

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

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