Is EXE A Virus? Is It Dangerous?

By

An Exe file is an executable file used by operating systems like Windows to open programs. If you are asking “Is Exe a virus ? Is it dangerous?” then you are doing the right thing. .Exe files contain binary code that is executed by the operating system when you open it (usually by double-clicking on it). .Exe files can be VERY DANGEROUS. Most Windows programs run through a .exe file, unfortunately, most viruses too. That’s why it’s so important to be able to tell if is Exe a virus or not without even using an antivirus.

What Is An .Exe File?

Most programs on Windows run on an .Exe file. If you are reading this article on Chrome, you have a Chrome.exe file running on your computer currently. It’s the same for any other software you have installed on your computer. Almost all softwares run with a .exe file. Actually, your Windows itself is composed of many .exe files running at the same to try to offer you all you need on your computer. Your desktop is a .exe, File Explorer is a .exe, your windows calendar is a .exe…almost anything on Windows is a .exe file.

Are .exe Files Dangerous?

Most viruses spread through .exe files. They usually run in the background without an interface to perform malicious operations on your computer. Most infections happen when you think that you are executing a clean program on your computer but it’s in fact either a virus or a legitimate program but injected with a virus that runs along with the program.

Therefore, telling if is .exe a virus is crucial. You have to be careful when downloading .exe files on the internet. Executing files that contain viruses can sometimes completely destroy your Windows 10 installation, even worse, delete or corrupt all your personal images and videos.

If you have downloaded a suspicious .Exe file from an unofficial website then you should probably not running it until you are 100% that it’s clean. We will see how to tell if is exe a virus or not.

How To Tell If Is EXE a Virus Without an Antivirus

Before opening .Exe files on your computer you have to be very cautious. There are few signs that can tell you if is Exe a virus or just by thinking about it for a second

Size of the file

Viruses a generally small-sized (not more than 1MB in general). If you are expecting to download a program like Firefox that has around 50MB but got a file with only a few kilo-octets then it’s probably a virus. But beware that a big file doesn’t necessarily mean that it’s an authentic file. Viruses can be injected into a program’s executable making it unnoticeable this way. The virus runs in the background while you run and use the program without noticing.

The Format Of the File

The rule is simple: If a file is not in the extension you are expecting it, then don’t run it.

.Exe files are only used to launch programs, if you have downloaded what you thought is a PDF or a video but got a .exe file then delete it immediately. A lot of websites disguise as legit download pages for the files you are searching for online (Like videos, documents, etc) but make you download a .Exe file instead of .MP4 or .PDF.

Icon of the file

Most viruses are just .exe files without icons. If you have downloaded an .exe file that you know it should have an icon (Like the Firefox Icon if you have downloaded Firefox) then don’t open it. Please note that a .exe file that has an icon is not necessary safe.

If you have downloaded a .exe file from the internet, you should scan it for viruses with an anti-virus before running it on your system. Windows 10 has a built-in antivirus called Windows Defender that can detect almost any virus. You can also either use third-party software like Kaspersky or Bitdefender.

If you want a free and very powerful antivirus, I suggest using Kaspersky Security Cloud Free. It’s a free antivirus using the same detection engine and viruses database as the paid Kaspersky antivirus.
