Also, you may try this...
- Check is avast! running at all - check your taskmanager, and see if you can find avast! processes in there.
- If it is not up and running, try repairing avast! (control panel - add/remove - avast! - change/repair). Note: You must be connected to the internet while performing avast! repair.
- If it is up and running and you still don't see your icons, give RejZor's AEC (avast! External Control) a try. Search these forums for a link.
- If all of that fails, then uninstall avast! using the uninstall utility from the website, reboot and reinstall it from the scratch.
Cheers !
Edit: Also make sure your icons are not set to auto-hide in the taskbar properties (Windows).Also, take a look in here:
