Downloading software in .rar or .zip format from unverified community posts (like "solid post") carries significant security risks. Malicious actors often use these filenames to distribute:

: Repositories like the mishakorzik ProxyChecker allow you to inspect the Python code before running it.

: Use reputable online tools like ProxyChecker.org or HideMy.name that don't require any software downloads.
