What's Hot: As I mentioned, Ad-Aware comes in three different flavors. Ad-Aware 2007 Free, Ad-Aware 2007 Plus, and Ad-Aware 2007 Pro. All three versions come with the improved scanning and removal engine that makes this such a great product. If you want real-time protection, a necessity in my book, then you'll need to get Ad-Aware 2007 Plus. For a little more money, you can get Ad-Aware 2007 Pro, but most of the additional features are aimed more at small businesses or corporations that have a need for network drive scanning and more advanced command-line support. Unless they're running their own network, the average home user will be more than satisfied with the features in the Plus version.
The feature that that impressed me the most is the real-time protection, called Ad-Watch, that is constantly monitoring your system while you work or browse the Internet, and automatically removes malware before it can infect your PC. I'm a huge fan of programs that offer automatic protection, because let's face it: how many of us really remember to run all the different assortment of PC protection and clean-up utilities on a regular basis? This feature alone is worth the small cost of skipping the free version and getting the Plus version.
Ad-Aware 2007 Plus comes with two main programs. Ad-Aware and Ad-Watch. As I mentioned, Ad-Watch is the real-time monitoring module. It not only watches for incoming adware and spyware but also includes Ad-Watch RegShield, which protects your registry from changes made by adware; Ad-Watch Process, which blocks programs from automatically launching on your PC; Ad-Watch Connect, which lets you look at all programs that are trying to connect to the Internet and send information; Ad-Watch TrackSweep, which allows you to remove Internet clutter such as cookies, your browser cache, and your Internet history; and Ad-Watch Cookies, which will automatically delete tracking cookies from your PC that may contain adware or spyware.
The main Ad-Aware program is where you'll be able to change configuration settings, run manual or scheduled automatic scans of your system, look at log files, or access other features such as the Host File Editor (used for blocking advertisement sites and preventing programs from hijacking your browser).
When you run a scan, Ad-Aware defaults to quarantining files that it removes in case you need to restore them later. You can always change the settings to immediately delete all threats found, if you prefer. I ran the manual scan on my 500 GB hard drive; it only took eight minutes to run and found over 200 tracking cookies that it labeled as threats. A comparison scan with Norton Internet Security only found four of these same threats. Clearly a program solely designed to detect spyware and adware is more effective.
What's Not: I'm a big fan of automatic updating, since it keeps the software always up to date for users who forget to run the updates on a regular basis. The problem I have with the new version of Ad-Aware is that it seems to be extremely slow running the updates, and a few times I received an error message about a problem connecting to their server. It's even worse if you have it set to check for updates when you start the program.
Ad-Aware 2007 now includes a module called TrackSweep, which is designed to remove all traces of your Internet activities. This feature supports Internet Explorer, Firefox, and Opera. Although it works well, not everyone might want this feature since it also removes all your browsing history.
Besides the slowness of the automatic updates, there aren't really any downsides to running Ad-Aware 2007. It has all the features that you would expect in an adware removal program and it does its job very well without slowing down your system.
