I hadn't run AdAware for a long time so I tried it. It reported 304 items. 303 were tracking cookies/data miners which AdAware itself classifies as low risk. "...used either for targeted advertising, or tracking users across a particular website, such as page views or ad click-thrus." Those things don't worry me and can be controlled with cookie settings if you really want to, otherwise, they're pretty much inevitable. Number 304 was a site I had added to my favorites. AdAware listed it as a "possible Browser Hijack attempt" because they had apparently blacklisted the site--I've noticed nothing fishy about it. One of the things I like best about MSAS is that it is always running blocking hijacks, home page changers, new startup programs, new toolbars etc. AdAware has realtime protection but only in the pay version. I'm sure if I had run SpyBot, it would have found something else the other two didn't. As someone said, it's probably best to run at least a couple of different ones. Personally, I use the ZoneAlarm, AntiVir and MSAS and call that a reasonable solution that I can manage and so far hasn't let me down. Various other combinations are just as good, all a matter of choice.
