The other day a new version of avast was available. I d’loaded and installed it. It’s version 4.7.986. After it installed it asked if I wanted to restart now or later. I selected “later”.
Now everytime I start my computer, I get a message that asks if I want to reboot now or later. I always select “later” and that’s the last time I see the message and the computer runs fine.
Just for a change say Yes, allow it to reboot and see if that clears it.
If nothing has changed.
Operating system restart needed by avast message - First check the contents of the C:\Program Files\Alwil Software\Avast4\Setup\setup.log file, which should show you why it thinks the reboot is needed.
This could be solved, in some systems, by deleting the file C:\Program Files\Alwil Software\Avast4\Setup\reboot.txt
