Add Spybot Search and Destroy to your protection setup.It's a free download from www.download.com. The interface isn't as friendly and as well laid out as Lavasoft AdAware but it picks up one or two that AdAware misses and vice-versa.Run them both...they don't conflict and they do the job admirably.You could try Windows Defender ...it used to be called "Giant antispyware"..Uncle Bill Gates bought the company and renamed the software..It scores well in that it runs in the background and doesn't gobble too much in the way of resources...its big advantage is that it runs in real time and stops the nasties before they get onto your setup...
