Previously known as Windows Antispyware Beta 1, Windows Defender (Beta 2) is a free program that helps protect your computer against pop-ups, slow performance, and security threats caused by spyware and other unwanted software.
It features Real-Time Protection, a monitoring system that recommends actions against spyware when it's detected, and a new streamlined interface that minimizes interruptions and helps you stay productive.

New name, but more or less the same as Windows Antispyware. I don't really trust the real time protection. For that I prefer paying for a full suite that will really do the job. This program is a bit of a mess to install, what saves it is that it is (luckily) completely free. Seems to update regularly too. I'll leave it on just in case, but definitely won't rely on it too much.
Laws concerning the use of this software vary from country to country. We do not encourage or condone the use of this program if it is in violation of these laws.
