We are living in the paradise of the internet where telecommunication has brought absolute changes to our digital lives.

What is a link between Console Windows Host and A Virus?

If we talk about an ideal world, free of hackers and viruses then to be very honest there is no link between these two but in this bad world of theft, there are indirectly interlinked, how? Actually, conhost.exe is one of the major Windows components and your window might not work properly if you uninstall or delete this file so protecting this file is necessary if you don’t want your windows to crash unexpectedly.

As I mentioned above, this file is very important for windows to work so hackers and virus producers started playing trick cards to fool window users by creating viruses with executable files with the same name.  Now how it works? A virus will be active on your computer with the name of the conhost.exe and you will not pay your attention to it thinking it as a regular windows file. This virus file will be executable so it can steal your personal information and data without your knowledge. This duplication of these files can drag you into confusion but you don’t need to worry about it because you can easily trace out the real one.

How DO I know CONHOST.EXE on my computer is not a virus?

It is easy to locate, just got to your system drive C > Windows > System32 Folder but what if exploiter was successful in putting a conhost.exe file containing the virus in that same folder? In this case, you can find a real file by its size. Usually, real consol windows host file will be of 271,360 bytes. You can hover over the file or right click on it then go to properties and find its size.

How To Differentiate Between A Virus And Real Console Windows Host File?

Just keep following mentioned steps in your mind and you will never have to face the problems regarding suspicious virus files with the same name. As we have had discussed it earlier, the easiest way to detect the real and fake file is by its size. if the conhost file is smaller or larger than 271,360 bytes then it is understood that the file is suspicious or contains a virus. What if a trojan writer has created a similar file with the same size?


Still, no worries because we still have a very good solution for you. For example, if you find duplication of the real file inside user’s or windows folder and its size is one from the given list then you are dealing with a virus.

  • 267,776 bytes
  • 657,920 bytes
  •  2,445,824 bytes
  • 338,432 bytes

but if this conhost.exe file is located in the any of the subfolders inside the C drive then files with the size of 5,714,944 bytes or 267,776 bytes are viruses.

If this console windows host file with the executable extension is lying inside the windows folder with temporary files with the possible size of the 152,064 bytes then you are in trouble.

It is important to Mention here that do not delete a conhost.exe file if you are not sure because this file runs at the background and its deletion will result in windows failure or maybe some programs will not work properly. Another thing that should be noted here is the start time of the conhsot file that contains a virus. This trojan file launches along with your system files when you reboot your system which means that it behaves similarly like your real conhost file.
