My problem is that AVAST asks every day to restart the computer. When I press the update>program button it ALWAYS asks to restart the pc. This cant be because I dont believe avast is updating every day the program. is it?
No... avast program isn't being updated on daily basis. Only the virus database.
What is silent mode actually?
Running mode. This setting controls the behavior of
manual updates.
Automatic updates are always "silent".
Normal. When an update is performed, avast! will display a summary. Optionally, the progress of the update can be shown.
Silent. The updates will be performed completely on background, no messages will be shown.
Other update options:
Show update progress. A small window will be shown during the update - you can watch the progress there.
Show icon in task bar tray. An icon will be shown in the system tray during the update.
Ask for reboot when needed. Some updates may need a reboot to take effect. By checking this option you will set that the operating system restart will not happen automatically - a window will pop up asking whether you want to restart now or later.
Show sliding box after automatic update. When an automatic update is performed, a small notification window will be displayed above the system clock.
Show sliding box on error. If an error occurs during an automatic update attempt, a small notification window will be displayed above the system clock.
Auto-update interval. Here you can set the interval of the automatic updates (i.e. how often avast! checks whether a new update is available).
The "do not ask for reboot" option makes it even more complicated.
Why?
