How can I ensure the safety and security of a free Blogger template downloaded from a third-party site, especially if it doesn't require footer credit?

To ensure safety, only download templates from well-known and reputable template providers. Before uploading, you can scan the template's XML file for suspicious code using online tools that detect obfuscated JavaScript, unusual external scripts, or hidden links. Check user reviews and comments for the template for any reported issues. After installation, continuously monitor your blog for unexpected redirects, pop-ups, performance issues, or any abnormal behavior that could indicate malicious code.
