If found on an obscure forum or via a pop-up, treat it with high suspicion. 2. Scan for Malware Never extract an unknown archive without a security check.
Be wary if the archive contains .exe , .bat , .vbs , or .js files, especially if you were expecting a document or an image. 4. Check for "ReadMe" Files
Do you remember this file or what device it was supposed to be for? Provide those details and I can help you identify it!
