COM surrogate virus Removal Guide
What is COM surrogate virus?
COM surrogate virus is the malware that alters various settings and hides its purpose behind Windows processes
The virus runs in the background by mimicking the vital Windows process and performs various malicious activities, including data stealing.
COM surrogate virus is a malicious version of the Component Object Model – a legitimate file used by the Windows operating system that usually runs in the background and is related to the dllhost.exe. While the initial functionality of COM is to allow the creation of COM objects used by Windows, the file that is disguising under the same name is here for much more malicious purposes.
Since 2015, hackers have started camouflaging this process to disguise malicious Trojan horses, such as Trojan.Poweliks. According to reputable security vendors, a more precise name for this malicious process is Dllhost.exe 32 COM surrogate virus. The infiltration of such treats might reveal sensitive information about users and even allow hackers to steal money directly from a bank account.
Masking malicious executables by using Windows legitimate names is not a new tactic, as hackers are merely trying to mislead users to make them think that the virus is just another harmless process. In reality, any executable can be replaced, duplicated, or corrupted by malware. To separate malicious executables from legitimate processes, users should run a scan with security software and check the file's location (it should be C:\Windows\System32).
