: If the "zip" actually contains an .exe or .scr file when you expected a document or data file, do not run it.
: Compare the file size on the download page with the actual size on your disk after the download finishes to ensure it isn't corrupted. 3. Extracting the Contents Software Needed : Use a tool like 7-Zip or WinRAR .
