Avast Problem – How to fix Avast not starting

The typical scenario: It’s early morning and I get to the office, light up my PC, log on to Windows Vista and there there. The Avast icon has a little red no-entry icon on it.

This case happens more often than it should. Thanks to this (annoying) frequency, I managed to fix the problem. If you’re lucky, you’ll only have to restart the Avast Antivirus service by following the steps below.

Start > Computer (right click) > Manage > Services and Applications > 
Services > avast! Antivirus (right click) > Restart

But if that does not fix anything, you’ll have to do 2 things:

1. Repair your Avast Antivirus installation. Steps below.

Control Panel > Uninstall or Change a Program > Avast Installation > Repair

2. Restart your Avast Antivirus service by following the steps above.

That’s about it. This should do the trick for minor Avast problems.

    Yeah so I tried the first part but it doesn’t look like it worked at all. Then I tried the second portion but I could not repair it. Any suggestions?

    Thanks

    Hello, I’ve tried the first step but got an error window:

    “Windows could not stop the Avast Antivirus service on Local Computer”

    Error 1053 : The service did not respond to the start or control request in a timely fashion

    Got any idea what this is?

    Thanks
