What is Dllhost.exe malware

Dllhost.exe is a piece of malicious software masking itself under dllhost.exe (COM Surrogate) – a legitimate and important Windows process running by default inside of each system. By doing so, the virus attempts to prevent users from thinking it is something suspicious. It is also possible to see a number of genuine dllhost.exe processes in Task Manager eating tons of CPU resources. For instance, a trojan called Poweliks is known to exploit the legitimate process to execute its dirty work. The malware we are talking about today creates a separate fake process to execute its unwanted tasks. It was found that users affected by it see force-open websites like adult pages, casinos, gambling, phishing, scam, pornography, and other types of resources promoting potentially dangerous content. The list of possible malware functions does not end with forcing redirects only. Such infections may embrace screen/audio recording features, keystroke memorization, spying on sensitive data, installation of malicious programs like crypto miners, and other similar things. If you suspect being infected with Dllhost.exe-masqueraded malware, make sure you follow our tutorial below to detect and remove it immediately.

How Dllhost.exe infected your computer

It was recently found that Dllhost.exe malware is spread on a website promoting fake “cracked” software. Users could end up visiting it via dubious ads or links on unreliable third-party resources. Unfortunately, this is not the sole channel abused by Dllhost.exe malware promoters. It is likely that some other channels are in to ensure a broader grip on potential victims. The most common distribution techniques are implemented via deceptive downloads, malicious attachments or links in e-mail spam messages, phishing pages, fake software updates/installers, Peer-to-Peer file-sharing networks (e.g. Torrent clients, eMule, Gnutella, etc.), and so forth. We, therefore, recommend you avoid them and equip yourself with strong and up-to-date anti-malware software to combat such threats. You can find more information about it in the article below.
