Windows Experience Index error "Failed to properly assess the disk.

Hello, I have fresh windows 7 installed if I installed AVG Free Antivirus and after restarting my computer I wanted to measure the system rating index I got an error: Could not measure storage performance error failed to properly assess the disk. If I uninstalled AVG, there was no problem. Can you help ?? Thank you.

Hi Martin.
Please perform a Disk checking on your computer to check for errors such as lost sectors, bad sectors and corruption.

Follow these steps:
a. Click on Start and then click on All programs.
b. Now click on Accessories.
c. Right click on the Command Prompt and then select “Run as Administrator”.
d. Enter the following command and press enter.
chkdsk /f /r

Then, Perform a System File Checker (SFC) scan. SFC will make Windows replace corrupt or missing system files on your computer.
a. Click Start, click All Programs, click Accessories, right-click Command Prompt, and select Run as Administrator.
b. Click Continue or supply Administrator credentials if prompted.
c. In the Command Prompt window type the following, and press Enter:
sfc /scannow

Restart your PC, install AVG and check.
