: Compressed archives like RAR files are a common way to hide malicious content. Opening them can trigger scripts that compromise your computer.

: Before interacting with the file, use an online scanner like VirusTotal to check the file against dozens of antivirus engines simultaneously. Alternatively, tools like Jotti's Malware Scan allow you to submit suspicious files for analysis.
