open a suspicious archive directly on your primary computer.

If you see files ending in .exe , .scr , .vbs , .js , or .bat , do not click them . These are scripts/programs, not documents or images.

Be wary of files named things like BlackHistoryMonth.rar.exe . Windows often hides known file extensions, making a program look like a simple archive. 2. Use a "Sandbox" Environment

Simply open the archive to view the file list.

Where did it come from? If it was an unsolicited email attachment or a download from an unofficial site, treat it as high risk .
