Follow this universal guide to safely identify, open, and handle the archive. 🛠️ Step 1: Safely Extract the Archive

A file ending in .7z is a compressed archive created using 7-Zip or similar file archiving software. Because anyone can compress any group of files and name the folder whatever they want, the contents of your specific file depend entirely on where you downloaded it.

Download and install the free, open-source program directly from the official 7-Zip site or use NanaZip from the Microsoft Store.

To see what is inside, you must use a specialized tool that supports the .7z format.

Upload the PJK26.7z file to VirusTotal before extracting it to have dozens of antivirus engines analyze it for free.
