Avast has improved its installation process so it's faster than before. It's not the fastest on the market, not by a long shot, but a standard installation took us about three minutes -- around the same as last year.

Some items of note during the installation that will come up later in the review: To avoid the Windows 7 and Vista desktop gadget, or the WebRep browser add-on, you must choose the Custom install option and uncheck those here. Firefox and Internet Explorer will all block WebRep from installing by default, but it may be easier for some to cut it off here.

Unlike last year, installing Avast once again requires a reboot. Still, the uninstallation process left no detectable traces on the desktop or in the registry.

One installation option, available only from the custom install menu, lets you sideload Avast as a secondary security program to supplement your main one. We're not big fans of this option from a security point-of-view, because it can bog down your system resources without actually making you safer. However, as a way to see if you like Avast, it's not a bad thing as long as you remember to choose one security suite to go with.
