What is dllhostexe or COM Surrogate the thing that spams you music and ads?

Answer 1

DLLHost is an executable designed to load and run DLLs in memory that otherwise have no application host and would be unable to run. Many system functions are written as DLL files and hosted by DLLHost. Unfortunately, some virus, adware, and malware also use DLLHost to hide themselves in. DLLHost itself is a system function that's required to run your computer, but the culprit in this case is some software hiding inside DLLHost. You must not remove DLLHost from your computer, but you should use an anti-malware program (Windows Defender, AVG, Super Anti-Spyware, Spy Doctor, etc) to remove the malicious DLL that is spamming you with music and ads.
