Thanks for the info, so is it really good? Never tried or used any security product from MS before though

There better be xp support, it needs it most

Hopefully it is much better than Windows Defender.

Now Microsoft has officially announced that it'll release a public beta of MSE on June 23, 2009 at about 9 AM PDT. It'll be available for first 75,000 lucky people but Microsoft might increase the number if required.

After this first beta, Microsoft will release a second public build, either a Beta Refresh or a Release Candidate, for the summer. It'll be available as standalone 32-bit and 64-bit downloads for Windows XP, Vista, and 7.

You'll be able to download the public beta from following link on June 23:
