What is COM Surrogate Virus

The COM Surrogate virus is a malicious program that masquerades as the legitimate COM Surrogate process. The genuine COM Surrogate process is a component of the Component Object Model (COM) technology in the Windows operating system, which allows applications to interact with each other. The process is typically used to run a DLL as a separate process, isolating the main application from potential crashes. However, cybercriminals have exploited this process to create the COM Surrogate virus. This malware disguises itself as the dllhost.exe process, making it difficult for users and some antivirus programs to identify it as a threat. The COM Surrogate virus can perform a variety of harmful actions, such as stealing personal information, installing additional malware, or even using your computer as part of a botnet. The COM Surrogate virus is a type of malware that disguises itself as a legitimate Windows process to avoid detection. It’s named after the genuine COM Surrogate process (dllhost.exe) that is an integral part of the Windows operating system. This article will delve into what the COM Surrogate virus is, how it infects computers, and how to remove it.

How COM Surrogate Virus infected your system

The COM Surrogate virus typically infects computers through deceptive tactics. It can be bundled with free software downloaded from the internet, sent as an email attachment, or hidden in malicious websites or ads. Once the user unknowingly downloads and opens the infected file, the virus installs itself and begins its malicious activities. The virus is particularly deceptive because it mimics a legitimate Windows process. This makes it difficult for users to identify and remove the virus, as it can appear as a normal process in the Task Manager. Additionally, the virus can disable antivirus software or create firewall rules to prevent its detection.
