Before doing anything, upload the file to VirusTotal to check it against dozens of different antivirus engines simultaneously.

RAR files are usually safe to use. But just like regular files, compressed files (RAR or ZIP) can also contain viruses or malware.

If you were not expecting a file from a known contact, or if the context seems suspicious (e.g., a "business offer" from a random address), delete it immediately .

If you must open a suspicious file, do so in a dedicated virtual machine or a tool like Windows Sandbox to prevent it from reaching your main system.

Modern attackers use small RAR files to hide scripts that steal browser cookies and session tokens. This allows them to bypass two-factor authentication and hijack accounts (like YouTube or social media) without needing a password.

A legitimate archive for a game or software is rarely that small. 160 KB is roughly the size of a single text file or a small script, making it a "red flag" for a hidden executable. Safety Recommendations

Simply downloading the file is generally safe, but extracting or opening the contents can trigger the malware.
