Hi kama,

When I faced a similar issue with an unknown application consuming a staggering 500GB and being stubborn against uninstallation, I had to navigate through several steps to resolve it. Here’s how I approached the situation, based on my experience and some additional insights I've picked up along the way:

Identifying the Culprit

Initially, I used system information tools to get a clearer picture of what this application was. Both the built-in "System Information" on Windows and "System Report" under "About This Mac" on macOS were instrumental. I also scrutinized the list of installed programs for any anomalies. Safe Mode Strategy

I found that booting into Safe Mode on Windows (or Safe Boot on macOS) was incredibly useful. It stopped non-essential applications from running, which sometimes makes it easier to locate and remove the problematic software.

Leveraging Uninstaller Tools

Since the application didn’t budge via standard uninstall methods, I turned to third-party uninstaller programs. These tools are adept at rooting out not just the application but its scattered files and registry entries as well.

The Manual Tactic

With some detective work, I located the application's files via File Explorer (Windows) or Finder (macOS) and manually deleted them. I ventured into the Windows Registry only because I was confident in what to look for and delete. This step is fraught with risks and not recommended unless you're sure of the implications.

The Malware Scan

Considering the possibility of malware (given the application's odd behavior), I ran a thorough scan with a trusted antivirus. This step is crucial for identifying and eliminating potential threats that masquerade as legitimate applications.

Key Takeaways from My Experience:

• Backup First: Before diving into potentially risky territory, I ensured all important data was safely backed up.
• Proceed with Caution: Especially with manual deletions and registry edits, one wrong move can have significant repercussions. When in doubt, it’s better to pause and seek help.
• Stay Informed: Keeping abreast of how to deal with such software anomalies not only solves the immediate problem but also prepares you for future issues.

Reflecting on this experience, it underscored the importance of not only addressing the issue at hand but also reinforcing my system’s defences against similar challenges in the future.

I hope this also works for you? If you have any questions please let me know.
