Free Software and Freeware

For a good overview of what spam is, why and how they do it:

Simply put, MailWasher allows you to preview and delete emails on the server before you download them to your computer with your email client.

Use this spam blocker software to effectively stop email spam. Discover the safe way to stop unwanted e-mails before they get to your computer. No gimmicks here, it is so easy to set up and use that you'll be managing your email like a pro in seconds. It can even be used as an effective privacy tool. Add addresses to friends or the blacklist, and they'll be automatically listed with either a red or green indicator. If you're fed up of having to trawl through your in-box just to find your 'proper' emails, then after a short while you'll start to notice the time and effort this little program can save you.

The video demonstration below is for the 'Pro' version, but the interface is so similar, that it still gives a good overview.

I think this is by far the best free PDF reader software currently available. This has all of the features of most PDF Readers, plus some! I know that Adobe produce their own free PDF, but unfortunately it's now a very large program. This has had the knock on effect - it takes ages for the program to start, and you also have to buy the commercial version to get many of the features PDF-XChange Viewer provides for free!.

With PDF-Xchange Viewer you can view, print, search, zoom, copy/export text & images. You can type notes and annotations on your PDF's in any font or colour, and fill-in and save forms. You can embed sticky notes, or rubber stamp documents aswell as bookmark articles or pages, all within a nice tabbed interface.

I use this instead of the highly popular FoxIt Reader which is a very small and fast PDF reader (which also comes in a portable version should you require this), but for features alone the free PDF-XChange Viewer from Tracker Software cannot be beaten!
