my surfing is too slow-quite urgent Please

Hello’
my surfing is too slow. the official ADSL + ISP support has proved to me that the reason is the Avast.
how can I configure it for faster internet surfing?
TIA

When did you start to experience this issue?

I suffer from this since I installed Avast Free Antivirus 2014.9.0.2013

Did you have any other AV/Firewall before avast!

If so, did you remove them with their respective removal tool?

If not do that and then commence a clean install…

I’d recommend a clean install to v9.0.2013

  1. Download Avastclear, Rejzors uninstall tool and the appropriate Avast program edition

Note: You need to be ONLINE during this install (online installer works in all cases whereas offline sometimes doesn’t)

Avastclear : http://files.avast.com/iavs9x/avastclear.exe
Rejzors Uninstall tool: http://rejzor.wordpress.com/avast-cleanup-tool/

  1. Uninstall Avast by control panel [If you don’t have Avast in control Panel go to #4]
  2. Uninstall in safe mode using Avastclear.
  3. Run Rejzors Uninstall Utility in Normal Mode (removes traces avastclear doesn’t) - reboot.
    Check : Once uninstalled check in device manager>view>show hidden devices if there is anything related to avast with a yellow triangle… if so, uninstall it and reboot.
  4. Install the version you downloaded.
  5. Reboot.
