Dsapi.exe Malware


Dsapi.exe

Dsapi.exe is a hazardous PC virus capable of spying on you and starting harmful processes in the computer. Dsapi.exe operates as a Trojan Horse infection, when located in the C:\Windows or C:\Windows\System32 folder, using different stealth and disguise techniques to attack the systems of its potential victims.

The Dsapi.exe malware

Trojan horse threats, in general, are known for their stealthiness and overall lack of infection symptoms. However, sometimes there may be certain signs that could indicate that there’s something wrong with the system and thus draw the user’s attention to the virus’ presence.

Among those potential symptoms are unusual software errors, system sluggishness and slowdowns due to excessive use of resources such as RAM, CPU time, and even GPU (even though no resource-demanding programs are being run at the moment). Another concerning symptom that should tip you off about the presence of some kind of problem is the appearance of the Blue Screen of Death on your monitor. In other words, this is when your computer crashes and isn’t able to start normally so a blue screen with an error message written on is displayed. All of the aforementioned symptoms, however, could be linked to many different issues and a Trojan horse infection is only one of them. Nevertheless, if you have indeed noticed any of those concerning red flags, or any other disturbing irregularities on your computer, we strongly recommend that you check your system for the presence of the Dsapi.exe Trojan.

Possible uses of the Dsapi.exe virus

There are many different possibilities when it comes down to how a Trojan virus could be used since this type of threats is typically very versatile. Here are a couple of examples of how a threat like this could damage your system.

File and software corruption is one of the most common forms of harm that Trojans cause to the attacked machine. The BSOD crashes and errors we mentioned earlier are oftentimes triggered by the damage that Trojans cause to the system.

Another thing that Trojans like Dsapi.exe and Wup.exe tend to be tasked with is taking over the attacked machine and allowing the hackers to remotely control it through the Trojan. Once such control is established, one of the most common things the infected machine gets tasked with is the mining of cryptocurrencies. Some Trojans create whole botnets of infected systems, all of which are forced to mine such currencies and then send them to the hackers’ virtual wallets. Spam message distribution and Denial of Service attacks are also commonly conducted by the computers from the Trojan’s botnet.

The third Trojan horse use we will mention here is the distribution of other viruses and, most notably, that of Ransomware cryptoviruses. Oftentimes, after a Trojan like Dsapi.exe attacks a given computer, it will secretly download the Ransomware onto the already infiltrated machine and then the Ransomware will begin the lock the user’s files.

If you want to prevent any of this from happening to you, we strongly advise you to make use of the removal guide you will find below and, with its help, remove Dsapi.exe and make your computer safe and secure once more.

    Step4

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

    msconfig_opt

    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:

    hosts_opt (1)

    If there are suspicious IPs below “Localhost” – write to us in the comments.

    Step5

    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!
