[KB2503] Why does my computer freeze while installing Microsoft Windows 7 and Windows Server 2008 R2 Service Pack 1 (SP1)?

Solution

Upgrade to the latest version - End of Life notice

This article applies to version 5.x of ESET Endpoint Antivirus and ESET Endpoint Security. These products are currently in Basic Support status and are expected to reach End of Life status in December 2020. After this date, ESET Endpoint Antivirus and ESET Endpoint Security will no longer receive detection engine updates to protect against malware.

This issue is caused by a conflict between the SP1 installation and the Real-time File System Protection module of your ESET  product. To resolve this issue, begin with Solution 1 and only proceed to Solution 2 if the issue persists.

Solution 1: Upgrade/update your ESET product

  1. If your ESET product is NOT version 4.x or newer, click here to upgrade to the latest version. For instructions on how to determine which version you have, click here.
  2. If you are already using version 4.x or newer, click here to ensure you have the latest virus signature database.

If these steps do not resolve your issue, please proceed to Solution 2.
 

Solution 2: Disable Real-time File System Protection and install SP1

If Solution 1 did not resolve the issue, you must temporarily disable Real-time File System Protection before installing SP1. To disable Real-time File System Protection, follow the steps below:

Administrator rights

To disable the Real-time File System Protection module, you must be logged in from a user account that has administrator rights.

  1. Open ESET Smart Security or ESET NOD32 Antivirus. How do I open my ESET product?
     
  2. If you see Display: Standard mode in the lower left corner, switch to Advanced mode by clicking Change… or by pressing CTRL + M on your keyboard.
     
  3. In the main program window click Setup → Antivirus and antispyware.
     
  4. Click Disable in the Real-time file system protection section of the primary window. The Real-time File System Protection module status will change to Disabled and the status icon will turn red.

  1. Begin the SP1 installation.

Re-enable Real-time file system protection

The Real-time file system protection module should be re-enabled automatically after your computer restarts (required by the SP1 installation). If it remains disabled, repeat steps 1-3 above and click Enable under Real-time file system protection. Leaving the ESET Real-time file system protection disabled will increase the risk of  your computer becoming infected.
