Simple User Interface not appear

I am not able to use Simple User Interface and scan my storage on demand.
Only icon on taskbasr there is, but SUI window does not appear
(even if I left if for a few hours).

Memory test finished correctly, next icon on taskbar avaialble and nothing more.
By context menu (right click on taskbar icon) I can only “Close” it or open “About avast!”.
There is nothing in Avast log file.

No other antivirus software installed anytime (before of after avast).
Also never spy tools or something like that. No Firewalls, windows Firewall off.

Avast Home: Build 2007 4.7.1001
Virus database: updated successfully 000749-0
Windows: XP SP2 (also updated)

Kindly advice.

Can you try to repair your installation?
Go to Control Panel > Add/Remove programs > avast! antivirus > Remove. Then choose Repair function in the popup window (Repair). You must be connected to the internet while repairing.

If this does not help, can you uninstall / boot / install / boot again?
After that, can you post the results?

Repair did not help.

I needed to install again exactly as you requested.
I have no idea what was a reason but now it is working fine, I have got SUI console.
We will see how long. Maybe I will back soon to that topic :wink:
Thanks a lot for assistance.
