By default, the WebMonitor application is packed by UPX.
If you wish to unpack it then you will need to download UPX from https://upx.github.io,
head to the download section and get the win32-edition, extract the UPX executable (upx.exe) and place it somewhere easily accessible from CMD, i.e. C:\ and the file to be unpacked as well.
Open up CMD and enter “cd c:\” (without quotes) then “upx -d xyz.exe”, where “xyz” represents the filename of the target file to be unpacked.
Your file should now be unpacked!
