Antivirus Blocking System Restore — Causes & Fixes (Third-Party Support)

Overview

System Restore is a built-in Windows feature that helps you roll back your system to a previous state when something goes wrong. But sometimes, your antivirus program may interfere with System Restore, stopping it from completing successfully.

This guide explains why this happens and how to fix it. If you’d rather not troubleshoot alone, avguide-help provides independent third-party support to ensure your restore process completes safely.

Why it happens

Antivirus locks or quarantines files that System Restore needs to copy back.
Real-time protection can block the restore engine from writing system files.
Conflicting drivers or services installed by security software.

Quick fixes (summary)

Temporarily disable real-time protection and retry the restore.
Use Safe Mode to run System Restore with minimal interference.
Check antivirus logs and restore quarantined files if needed.

Why Antivirus Blocks System Restore

Real-time protection interrupts file rollbacks.
Antivirus sees restore operations as suspicious changes.
Registry or system file restores trigger false positives.
Incomplete or corrupted restore points conflict with security software.
Multiple security tools (firewall + antivirus) blocking access.

Common Errors You May See

System Restore did not complete successfully.
An antivirus program is preventing System Restore from running.
Unable to access restore point due to security restrictions.
Restore process starts but stops midway with no changes applied.

Quick Fixes You Can Try

Temporarily Disable Antivirus
Open your antivirus dashboard, find Protection / Real-Time Protection / Shields, temporarily turn them off, then run System Restore again.

⚠️ Important: Re-enable your antivirus immediately after System Restore finishes.

More Quick Fixes You Can Try

Run System Restore in Safe Mode
Restart your PC → Press F8 / Shift + F8 / F11 (depends on your system).

Choose Safe Mode with Networking.

Run System Restore from there. Safe Mode loads minimal drivers and usually bypasses antivirus interference.
Use Windows Recovery Environment (WinRE)
Press Shift + Restart → Choose Troubleshoot → Advanced Options → System Restore.

This method runs outside of normal Windows, reducing antivirus conflicts.
Exclude System Restore in Antivirus Settings
Open your antivirus → Go to Exclusions / Exceptions.

Add C:\System Volume Information and related restore files.

Retry System Restore.
Uninstall & Reinstall Antivirus (Last Resort)
If the antivirus is corrupted, uninstall it temporarily.

Complete System Restore.

Reinstall antivirus using the latest installer from the official site.
