Yup. I didn't like the new version of Ad-Aware. I find the interface is really clunky, not a patch on what it used to be. Some excellent free alternatives:
Malwarebytes:

SuperAntiSpyare:

I use both of these programs. They are legitimate (something you sadly doesn't go for all anti-malware programs these days) and they are very effective as long as you keep them up-to-date. They both have paid versions available just like AdAware, but the free versions are pretty feature rich.
