Hello.
Clean install of windows 7.
Installed avast, AvastUI.exe ran at startup.
Installed windows updates, updated avast.
Now, no GUI on boot.
No stupid mistakes by me (like unchecking show tray icon etc.)
Question 1: How to get the tray icon back.
Question 2: Is the antivirus still active without GUI?
By the way, adding avastui.exe to startup loads the GUI correctly, annoyingly however, the whole user interface loads. Which means my dad has to close it every time the computer starts. And, "effin b-locks" to that, as my dad would say...
