What Causes the Error 42125: ZIP Archive is Corrupted?
This error usually occurs when attempting to uncompress a ZIP file. Users of Avast antivirus have reported seeing this error during boot-time scans. While the exact cause remains unclear, several factors may contribute to the issue, including:

If the ZIP file is password-protected, you must enter the correct password before extraction. If Avast displays the 42125 ZIP Archive is Corrupted error during a boot-time scan, ensure that the archives are not password-protected, as some software may not prompt for a password and will instead show an error message.

2. Update Your Drivers
Many Windows users have resolved this error by updating outdated device drivers. Here’s how to do it using Device Manager:

1. Open Windows Search and type Device Manager, then select it from the results.
2. In Device Manager, look for devices marked with a yellow exclamation mark (!). These indicate drivers that need updating.
3. Expand Display Adapters, right-click on your graphics card, and select Update Driver.
4. Choose Search automatically for updated driver software.

3. Run the System File Checker Utility
Corrupted system files can also trigger this error. The System File Checker (SFC) utility can help identify and repair these files. Here’s how to run it:

1. Open Windows Search and type CMD. Right-click on it and select Run as administrator.
2. In the Command Prompt, enter the following command:

sfc /scannow

3. Wait for the scan to complete, then restart your computer. This may resolve the 42125 ZIP Archive is Corrupted error.

4. Check for Hard Drive Errors
After running the SFC utility, it’s advisable to check your hard drive for errors using the Check Disk Utility (ChkDSK):

1. Open Windows Search and type CMD. Right-click and select Run as Administrator.
2. In the Command Prompt, enter the command:

(Replace C with the appropriate drive letter if your ZIP file is stored on a different drive.)

5. Reinstall Avast Antivirus
If you encounter the 42125 ZIP Archive is Corrupted error during an Avast boot-time scan, consider reinstalling the antivirus program. Avast is not designed to scan protected or highly compressed ZIP files, which may lead to this error. Reinstalling or updating Avast from the official website may help.
