 ## Download ##
 You can download the compiled standalone executable `Close It.exe` [here](https://github.com/chaohershi/Close-It/releases). No installation required.
 
 Alternatively, you can download the source code and run the script `Close It.ahk` having AutoHotkey installed.
 
-**Please be aware that if you choose to download and run the executable, you will get warnings from your web browser and Windows SmartScreen.** This is totally normal as the the file is not signed (purchasing trusted code signing certificate would cost a lot of $$$). Nevertheless, the file contains no virus and is 100% safe. Feel free to do a virus scan if you are still worried! Of which I recommend [VirusTotal](https://www.virustotal.com/).
+**Please be aware that if you choose to download and run the executable, you may get popup window from Windows SmartScreen.** This is totally normal. It takes some time for Windows SmartScreen to recognize a new certificate like the one that Close It is using. Nevertheless, Close It is free and minimal and contains no malware of any kind. Feel free to do a virus scan if you are still worried! Or proceed by clicking on the "More info" link and then on the "Run anyway" button.
