I tried several unerase tools when I wanted to recover some important files. And the best experience I had with Advanced File Recovery. It restores photos, videos, documents, and other important files deleted by mistake or intentionally. It scans selected folders or the entire hard drive and shows all deleted files that can be recovered. You can also preview files directly in the program without actually recovering them. I like that different media types are supported such as memory sticks, hard drives, memory cards from digital cameras, floppies, external drives etc.

Sorry, may be I am late with my reply . There are many tag editors on the market, you can give some of them a try. mp3Tag Pro, Tag&Rename, Music Tag Editor. Some of them have more useful features, anothers -less ones. I chose mp3Tag Pro.

I googled out and found a nice download archieve where there are a lots of good video editing software.

I use Avast with only the standard shield active, and it's very light on resources

You can create a bootable Flash dive using unetbootin. It's only for Linux and Windows
