Are you emptying your temporary internet files ?

Clear Cache/Temp Files
Download TFC by OldTimer to your desktop
  • Please double-click TFC.exe to run it. (Note: If you are running on Vista, right-click on the file and choose Run As Administrator).
  • It will close all programs when run, so make sure you have saved all your work before you begin.
  • Click the Start button to begin the process. Depending on how often you clean temp files, execution time should be anywhere from a few seconds to a minute or two.  Let it run uninterrupted to completion.
  • Once it's finished it should reboot your machine. If it does not, please manually reboot the machine yourself to ensure a complete clean.

Avast Free 9.0.2013.
Windows 7 Ultimate 64-bit SP1.
No other security products installed before or with avast.

3. Reinstall avast! with the downloaded installer from point 1.

Add the two lines in your WebShield.ini

[General]
UseStreamFilter=0

Hello everyone,

I just tried this solution and it worked for me.

I am running Windows XP and my webShield.ini is at:
C:\Documents and Settings\All Users\Application Data\AVAST Software\Avast

I disable Avast Until Reboot, edited the file, and restarted. Avast's CPU usage is at zero and it's still happy.

Thank you for the help!
