Parchives. Great for adding recovery to any file. :) I use them [now par2cmdline-tbb] religiously for archives. I started doing this years ago after having CD-R's burned on a drive (Plextor, no less) that I started having a hard time reading on any other drive.
Bitdefender likes to revert to default settings frequently. I prefer Windows Firewall (Win7) and have to turn off the Bitdefender firewall usually at least once a week.
LEDBenchmark [1] does a good job with their own spectrum and flicker graphs. So far, the LED bulbs I have gotten based on their results have been good.
