What Causes the ERR_CONNECTION_RESET Error?

The ERR_CONNECTION_RESET error happens when something interrupts network communication. In some cases, security software can interfere with web traffic and trigger the problem.

Common causes include:

Antivirus software conflicts
Corrupted application files
Browser cache problems
Network configuration issues
VPN or proxy settings
DNS problems

If you’re using Kaspersky and the problem appeared unexpectedly, the Report folder issue is worth checking.

How To Fix the ERR_CONNECTION_RESET Error in Kaspersky?

Yes, there is a workaround that has resolved this problem for some Kaspersky users. The process involves rebuilding the Report folder.

Follow these steps carefully.

Step 1: Disable Self-Defense

Open Kaspersky.

Go to:

Settings → General

Turn off Self-Defense.

Step 2: Exit Kaspersky Completely

Close the main window.

Then:

Find the Kaspersky icon in the Windows taskbar or hidden icons area.
Right-click the icon.
Select Exit.

Make sure the application is completely closed.

Step 3: Rename the Report Folder

Open File Explorer and navigate to:

C:\ProgramData\Kaspersky Lab\AVP21.3\

Locate the folder named:

Report

Rename it to:

Report1

This forces Kaspersky to create a new Report folder.

Step 4: Shut Down the PC Completely

This step is important.

Use Shutdown, not Restart.

After the computer powers off completely:

Press the power button.
Log back into Windows.
Start Kaspersky again.

Step 5: Re-Enable Self-Defense

Go back to:

Settings → General

Turn Self-Defense back on. Then test your browser again and see if the ERR_CONNECTION_RESET error is gone.

Is This Fix Safe?

Yes, renaming the Report folder does not remove your protection settings or uninstall Kaspersky. It simply causes the software to create a fresh Report directory.

However, this guide specifically addresses a Kaspersky-related cause of ERR_CONNECTION_RESET. Other causes may require different solutions.

What If the ERR_CONNECTION_RESET Error Still Appears?

If the issue remains, other network-related causes should be investigated.

Check Browser Cache

Try:

Clearing browser cache and cookies.
Testing another browser.
Opening the site in private mode.

Reset Network Settings

You can also:

Flush DNS.
Reset Winsock.
Disable VPNs or proxies temporarily.
Test another network connection.

Can antivirus software cause ERR_CONNECTION_RESET?

Yes. Antivirus software can sometimes interfere with HTTPS traffic or network filtering, which may result in connection reset errors.

This is one of the more common software-related causes of the problem.

Why does the Report folder affect Kaspersky?

A corrupted or problematic Report folder can cause unexpected behavior within the application. Renaming it allows Kaspersky to generate a fresh folder structure.

Quick Summary

The ERR_CONNECTION_RESET error on systems running Kaspersky can sometimes be fixed by disabling Self-Defense, closing Kaspersky, renaming the Report folder located under C:\ProgramData\Kaspersky Lab\AVP21.3\ performing a full shutdown, and then re-enabling Self-Defense.

Restarting the computer may not be sufficient. A complete shutdown followed by powering the machine back on is part of the procedure.

This solution targets a Kaspersky-specific cause of ERR_CONNECTION_RESET and may not apply to all cases.

FAQ

Why am I getting ERR_CONNECTION_RESET on every website?

The error means the connection was interrupted. Browser settings, antivirus software, DNS issues, or network problems can all cause it.

Can Kaspersky cause ERR_CONNECTION_RESET?

Yes. Kaspersky’s network filtering components can sometimes contribute to the error, especially if internal files become corrupted.

Should I restart or shut down the computer?

A complete shutdown is recommended.

Will renaming the Report folder delete my settings?

No. Renaming the folder only causes Kaspersky to create a new Report directory.

Where is the Kaspersky Report folder located?

It is located at:

C:\ProgramData\Kaspersky Lab\AVP21.3\

The folder name may vary depending on your Kaspersky version.

Conclusion

If you’ve tried browser resets, DNS changes, and other common fixes without success, a Kaspersky-related issue may be responsible for the problem.

Here’s a quick recap:

Disable Kaspersky Self-Defense.
Exit Kaspersky completely.
Rename the Report folder to Report1.
Perform a full Shutdown, not a restart.
Start Windows and Kaspersky again.
Re-enable Self-Defense.
Check whether the ERR_CONNECTION_RESET error has disappeared.
