If I find a Goro Goro PDF, how can I verify its quality and safety before opening it?

Before opening a Goro Goro PDF from an unknown source, scan it with a reputable antivirus program. Check the file size – unusually small or large files can be suspicious. Preview the PDF (if your PDF reader allows) to check for missing pages or corrupted images. Be wary of PDFs that require you to enable macros or install additional software.
