1. Ad-Aware Free Internet Security
Our new Editors' Choice for free antivirus apps, Ad-Aware Free is effective at not only finding malware but also at blocking it (two things that don't always go together). Our reviews revealed it to be almost as good as the Pro version.

2. AVG Anti-Virus Free
AVG Anti-virus Free gets top marks at independent labs, and in our tests, it does a great job of finding and removing malware, though it isn't the best at keeping an already clean system clean.

3. Comodo Antivirus
Comodo does a great job of keeping systems free of malware, but in our tests, it didn't handle the heavy lifting of scanning and cleaning an infected system.

4. Malwarebytes' Anti-Malware
This tool is so fast and worthy that support people from other antivirus vendors will even suggest a check with Malwarebytes. Stick with the free version, as our tests of the Pro version indicate the "real-time protection" it offers isn't worth the money.

5. Microsoft Security Essentials
The latest version of Microsoft's free virus fighter adds some network-based attack protection, but overall it's much the same as the previous version. That means okay protection, and that's still better than nothing. And, of course, it integrates very well with Windows.

6. Panda Cloud Antivirus
It's no longer our Editors' Choice, but Panda still impresses with its ability to keep a computer clean from infection by using a cloud-based signature list of up-to-date viruses—all without a download to your computer.

When it comes to video podcasts, Miro goes far beyond iTunes by letting you subscribe to BitTorrent RSS feeds, with one of the fastest torrent downloaders in the world. Miro makes BitTorrent RSS dead simple-- when a new episode is available, it will download automatically and be ready to watch.
