Windows Vista does not have sufficient protection on it's own. Avast is legit, and it runs on the background, because it's protecting your system all the time. Run an updated full scan with: Malwarebytes and Spybot Search & Destroy Therafter check through with your anti virus, just to ensure it still works.
First: Use Avast's Custom Installation Advertisement Let's start at the beginning: When you first install Avast, we highly recommend choosing the Custom Installation option, as we do with all programs. This ensures you only get the features and add-ons you want, and none of the stuff you don't. By default, Avast's custom installation comes with a lot of things checked. Most of them shouldn't bug you too much, but we recommend unchecking anything you don't think you'll use. For me, that means unchecking the Software Updater, Remote Assistance, SecureLine, GrimeFighter, and Browser Cleanup features.
