Hi, my Avast! 4.7 Home Edition is showing a Icon like this: http://img243.imageshack.us/img243/2199/avasttraysuddste223wq6.jpg
. The Avast! icon usually changes and becomes active (without the red circle) and rolls around in the tray. It does that alot. I tryed reinstalling Avast! when I click Change/Remove, the computer does nothing.
Windows Security Centre shows that Avast! is working and up to date.
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?
Install again by this command on the folder you’ve donwload and save the install file: setupeng.exe /forceinstall
Where setupeng.exe is the name of the executable
If you really want to be sure of a complete registry cleaning, could be useful one of these Registry cleaning applications:
BeClean Specially the Registry Cleaning feature
But the best, you can make a download for try, is PowerTools. Very powerful registry power tools, with lots of extra options. Unfortunately, it’s a shareware. You can run it before the expiration time and get rid from the previous antivirus application. You can choose an option for backup of the removed itens.
