I've been using the
Microsoft Spyware Beta for a while now and I like it a lot. It just sits in the toolbar and stops bad things from happening. Well worth a download in my opinion.
While we are on the subject of good freebies from Microsoft, I also like the
MSN toolbar. Apparently this is based on Lookout, a product I mentioned some time back. It builds an index of all your files, emails and contacts and then lets you search them instantly (and I mean instantly). It seems to work very well and is one of those things that becomes part of your life very quickly.
I wonder if we'll ever have to pay for any of this good stuff? But in the meantime, grab them while they are going..
