How To Remove SvcHost.exe Malware (Virus Removal Guide)

The term SvcHost, also known as svchost.exe or Service Host, is a process used to host one or more Windows operating system services. The svchost.exe Microsoft Windows executable file is labeled as: Generic Host Process for Win32 Services. This is a required Windows file and is used to load needed DLL files that are used with Microsoft Windows and Windows programs that run on your computer.

This file is located in either the c:\windows\system32 or c:\winnt\system32 directories depending on your version of Windows and may also be located in the dllcache directory if present.

Because svchost.exe is used as a common system process, some malware often uses a process name of “svchost.exe” to disguise itself. The original system file svchost.exe is located in C:\Windows\System32 folder. Any file named “svchost.exe” located in other folder can be considered as a malware. Determining the image path of a process, and its invoking command line, can help identify software masquerading in this way, and help locate the actual program file which is running under the assumed process name of “svchost.exe” (Windows allows multiple processes to all display the same name). Some malware inject a .dll file into the authentic svchost process, for example Win32/Conficker worm.

How does the Svchost.exe malware behave?

Due to the generic nature of this infection, methods of installation may vary. The Svchost.exe infections may often install themselves by copying their executable to the Windows or Windows system folders, and then modifying the registry to run this file at each system start. Svchost.exewill often modify the following subkey in order to accomplish this:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run

If your computer is infected with the Svchost.exe virus, this infection may contact a remote host for the following purposes:

  • To report a new infection to its author
  • To receive configuration or other data
  • To download and execute arbitrary files (including updates or additional malware)
  • To receive instruction from a remote attacker
  • To upload data taken from the affected computer

How do I know if Svchost.exe is malicious or not?

Because svchost.exe is a common process in the Task Manager, malware programs sometimes mask themselves by running under the same process name of svchost.exe. Other times, a malware program may run, or inject, its service into an already running svchost.exe process. In either case, this masking action can make it difficult to detect and remove these malware programs.
The easiest way to see if your computer is infected with malware running under the “Svchost.exe” name, is to open your Windows Task Manager by pressing CTRL + ALT + DEL on your keyboard,
the right-click on the Svchost.exe which you suspect is malware, and then click on “Open file location

The SvcHost.exe from Windows should be located in the C:\Windows\System32 folder. Any file named “svchost.exe” located in other folder can be considered as a malware.

Should you be uncertain as to whether Svchost.exe is a virus or not, we encourage you to submit the affected file to https://www.virustotal.com/en/ to be scanned with multiple antivirus engines.

How did Svchost.exe infection get on my computer?

The Svchost.exe virus is distributed through several means. Malicious websites, or legitimate websites that have been hacked, can infect your machine through exploit kits that use vulnerabilities on your computer to install this Trojan without your permission of knowledge.

Another method used to propagate this type of malware is spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the Svchost.exe virus.

The threat may also be downloaded manually by tricking the user into thinking they are installing a useful piece of software, for instance a bogus update for Adobe Flash Player or another piece of software.
