avast refuses to start + unusual graphical glitches.

I have the latest avast free version under Vista. Avast loads fine at start-up and scans fine in real-time, but when I try and start the on-demand scanner it fails to load right away. The windows shows up and it looks like its scanning the memory before loading the main window and then it just disappears. I have to do this several times until finally on-demand scanner finally shows up.

Second problem is when it finally loads the on-demand scanner I get weird graphical glitches in the tray-icon pop-up menu. Sometimes the menu refuses to go away and stays on the screen as transparent attachment. This does not happen unless I load the on-demand scanner. I can fix the problem with the stuck menu by changing the resolution or rebooting the system but it happens again if I use the menu after loading on-demand scanner.

I have the latest patches, drivers, and minimal amount of software running.

Assistance would be appreciated. I’ve used Avast for years now and I would hate looking for a replacement.

Sorry if it will be a pain, but I suggest an installation from the scratch. Your problems are very difficult to troubleshot… interface, graphical glitches… How much RAM do you have? Any other security program that could interfere?

  1. Uninstall avast from Control Panel first.
  2. Boot.
  3. Download the latest version of Avast Uninstall and use it for complete uninstallation.
  4. Boot.
  5. Install again the latest avast! version.
  6. Boot.
  7. Check and post the results.
