Technically, a crack tool is not always a "virus" (a self-replicating malware), but it falls into the category of Potentially Unwanted Programs (PUPs) or HackTools. Here is the risk breakdown:

If you did not intentionally download this file, or if your antivirus flags it as severe, you should remove it immediately.

Step 1: Run an Antivirus Scan Run a full system scan with Windows Defender or a reputable third-party antivirus (like Malwarebytes).

Step 2: Manual Deletion If the file remains: r2rcertest.exe

Step 3: Check for Persistence

Instead of hunting for r2rcertest.exe, use:

Test-RDGatewayConnection -GatewayServer rdg.company.com -UserName "MYDOMAIN\jsmith"

Or check certificate chain manually:

$cert = Get-ChildItem -Path Cert:\LocalMachine\My | Where-Object  $_.Subject -like "*rdg.company.com*" 
Test-Certificate -Cert $cert -Policy SSL -User

Currently, r2rcertest.exe is not associated with any major software vendors (such as Microsoft, Adobe, or Google). The name appears to be a compound of three elements that provide clues to its origin:

Likely Theory: Based on the naming convention, this file is likely a component of a software "crack," "keygen," or patcher released by the R2R group. It may have been designed to test the validity of a spoofed certificate or to patch software to bypass license verification.

  • Reporting: The tool logs its findings. Success results are typically only visible under verbose logging. Failures are written to the Windows Event Log (under Applications and Services Logs > Microsoft > Windows > TerminalServices-RemoteConnectionManager).

    • Important: You cannot (and should not) simply delete r2rcertest.exe from System32. It is a protected system file, and Windows File Protection will restore it. More critically, removing it will break RDP certificate validation, potentially preventing all remote desktop connections. Step 3: Check for Persistence Instead of hunting

    However, you can prevent it from running excessively by addressing its triggers:
