This page aims to help you remove Conhost.exe Virus. These Conhost.exe Virus removal instructions work for every version of Windows. “Conhost.exe что это” and “Conhost.exe high cpu” are just few of the things we have been asked about recently. 

  • The real Conhost.exe is usually a Task Manager Windows 7, 8 and 10 process that fixes some issues present on older iterations of the OS. Said issues are basically related to the way some of the integral parts of the system, mainly CSRSS.exe, worked. They were unable to be properly themed and had glitches or problems when an active theme was used on the system, hence the fix. An examination through Autoruns shows that the process is running under CSRSS.exe.

BUT! Here is the big thing you should note: in the modern era the Conhost.exe Virus is part of an unidentifiable group of threats that imitate and mask themselves behind the names of system critical processes. In the guide, we have devised a way to find out if the Conhost.exe Virus is in fact hiding in your PC or you are looking at the real counterpart. For many reasons you should NOT  delete any process unless you are 100% this is the Conhost.exe Virus in disguise. We suggest doing a backup and following the guide after that. If something goes wrong, you can just revert.

Is this Conhost.exe Virus a real virus or something else?

The Conhost.exe Virus can be practically anything, from a full-fledged malware to a simple Adware. If you are not versed in what these things actually mean, then here’s an explanation for you from lightest to most severe.

PUPs – potentially unwanted programs – is the lightest threat you can encounter. They are not really a virus as the name suggests, but rather something that may slow your system and display annoying messages, and are otherwise harmless.

Adware – these things are primarily viewed as a promotional tool. They DEFINITELY slow down your PC, are very annoying and hard to get rid of, and display countless advertisements. Why would anyone create such things, you may wonder? It is to promote certain products someone is paying for. The number 1 biggest way adware take root in your system is through being bundled with software.

Browser Hijackers – the same as adware, except they are created to drive traffic, meaning you, to certain websites, thus increasing their rank in google. It’s always for monetization purposes.

Trojans – this is where things really start to get rough. These are the things that can steal your accounts, passwords and personal information, as well as drain your credit cards. These are the tools that open doors to whoever created them to monitor and take into account your activities, before doing whatever they please a world away.

Ransomware – if you get hit by a Ransomware you should just “pay up” according to the FBI. Ransomware come into play with the help of Trojans and are by far the worst virus you can expect to encounter in normal-day activities. They backup your personal files and documents and encrypt them, demanding ransom (hence the name) for releasing them.

What is Conhost.exe?

  • Hi Lily,
    can you post a screenshot on what exactly is preventing you on completing this step? If you are using Microsoft Windows 10 you can also try Right Clicking the pinned icon on the Taskbar. After that from the bottom you can see “Unpin from taskbar” “Browser name” then you can Right click on “Browser name” and then it will show you Properties. Keep us posted if that doesn’t help.

  • Hi again,
    yes it’s ok to uninstall it like this but with this kind of viruses you can never be too sure. If you notice some suspicious behavior again don’t hesitate to contacts us. We are here to help you 🙂

  • Hi, in the section “Remove Conhost from your Browser” it looks like you’re advising to remove/disable the Adblock Plus extension, is that correct? How would you suggest we block unwanted ads on pages if we remove Adblock?

    • If you are referring to the screenshot in the guide, the ad-blocker from the image is just an example of how you can remove an extension from the extensions menu. The thing you need to remove is the unwanted app if you see it there, do not remove your ad-blocker.
