Verdict Malicious
Is rzr-
RAR archive contains a confirmed crack tool that injects processes and tampers with defenses.
Strong evidence · Two or more major antivirus engines agree.
Delete the file and avoid any crack or keygen utilities; they are reliably flagged as hacking tools and carry legal and security risks.
What to do now4 steps
This is a hacking tool. It is risky to keep and run, but finding it is not by itself a sign that the device is infected.
What to do
Don't open or extract it unless you got it on purpose for security testing on systems you own. Delete the archive and any files you extracted from it, then empty the Recycle Bin or Trash.
If you didn't put it on the device yourself, delete it and run a full antivirus scan: something else may have brought it.
Tools like this often come with cracked or pirated software. If it came that way, treat the whole download as unsafe and scan everything it installed.
If you already opened or extracted it
Stop using it, run a full scan with your antivirus and watch for unexpected behavior or security alerts.
If you opened or installed it
Avoid banking and sign-ins on that device until it is clean. These free MalwareTips guides walk you through it.

Why we think so
2 points against it and 0 in its favour, checked against the scan evidence.
The reasoning behind this verdict
22 of the 64 antivirus engines that checked it flag the sample, three of them major, agreeing on a crack/hacking tool label.
The hacktoolConfirmed flag is satisfied by multiple major detections and the sandbox evidence of offensive MITRE techniques. No code-signing applies to RAR archives, and the absence of contacted-host reputation data is neutral. The file is old and medium-prevalence, but these factors do not outweigh the confirmed hacking tool behaviour.
What We Detected
22 of the 64 antivirus engines that checked it report the RAR as malicious, with three major antivirus engines (ESET-NOD32, Fortinet, Sophos) labeling it a crack or hacktool.
Threat Behavior
Four files it created were dropped, none of which have independent malicious verdicts yet.
What To Do Now
Do not execute or distribute the archive. Keep security software enabled and delete the file. If the archive was obtained from an untrusted source, scan the entire system with current signatures.
Where this verdict could be wrong1 caveat
- No contacted-host reputation result was saved — no complete host-reputation cross-check available
These are the assessment's weak points. If you believe one applies to your file, report the verdict and we'll re-review it.

What the test run showed
What the file did on a test computer
Confirmed in the test run
Moderate concern: Contains packed or scrambled code that is harder to inspect (common in installers too).
Moderate concern: Checked whether it was running on a test computer.
Note: Listed the programs running on the test computer.
Note: Read basic details of the test computer, such as its Windows version.
Note: Loaded extra code modules while running.
Sandbox labels we could not confirm (common in safe files too)
Not confirmed: A sandbox rule tagged this run as code injection, but no injected program was recorded.
Not confirmed: A sandbox rule tagged this run as recording keystrokes; no keylogging was confirmed.
Not confirmed: A sandbox rule tagged this run as contacting a server, but no contacted host was recorded.
Not confirmed: A sandbox rule tagged this run as weakening security settings; no setting change was recorded.
This file was run on a test computer (a sandbox), not on yours. Labels we could not confirm are listed so you can see them, but they are not treated as evidence against the file.
Threat context
How hacking tools are used
Hacking tools are programs that can switch off security software, test passwords or attack other computers. Security professionals use them on purpose; criminals also bundle them with malware.
Bottom line:Keep it only if you installed it on purpose, and check how it got onto the device if you didn't.

Signatures and behavior heuristics
Low-severity pattern matches — worth noting but not on their own cause for alarm.
VirusTotal's sandbox summary maps this run to MITRE T1055 (Process Injection), but no injected process of the sample's own was recorded (the analysis VM's own WMI adapter, crash handlers and Chrome updater are not counted). VirusTotal maps T1055 on about half of all files no engine flags, so the mapping alone is not evidence of injection.
