Hi there! I understand you're experiencing an issue where TotalAV’s hard disk scan on your Mac stalls at 58.7 GB. Let’s work together to get this sorted out.

To start, could you tell me a bit more?
- Has this happened consistently at 58.7 GB every time you run the scan?
- Is the app freezing or just paused?
- Are you running the latest version of TotalAV on your macOS 10.15.7?
- Have you tried restarting your Mac or the app before the scan?

Meanwhile, here’s a straightforward approach to try:

1. Restart Your Mac
This can clear any temporary glitches affecting disk access.

2. Update TotalAV
Open the app and check if there are updates. Running the latest version helps fix bugs like scan stalls.

3. Run Scan with Fewer Apps Open
Close other applications so there’s more system resource available for TotalAV during scanning.

4. Check Disk Health
Since the scan stalls at a specific point, it might indicate file system issues or bad sectors. You can use Disk Utility (found in Applications > Utilities) to run “First Aid” on your hard drive. That checks and attempts to fix errors.

5. Reinstall TotalAV
If the problem persists, uninstall TotalAV completely, then download and install a fresh copy from our official site. Sometimes corrupted program files cause the scan to hang.

If after trying these the scan still stops at the same spot, it could also be related to particular files or directories causing trouble during the scan process.

Would you be comfortable sharing if the scan halts while scanning any particular folder or file type? If yes, I can guide you on creating an exclusion for those to get the scan through.

Let me know how you’d like to proceed! I’m here to help you fully resolve it.
