Confusion over digital camera megapixels

Dear CNET members,

Happy Friday! What I love about you folks is no matter how diverse a questions is, you all are always willing to jump in and contribute. And it's always great to read answers and opinions from you. I personally have learned so much. Best of all, it's nice to see new members each week doing their best to help another member out.

This week, V.K. asked a very good question regarding his confusion over digital camera megapixels; as always, many of you responded with some great explanations. Some answers were simple yet effective, and some were very detailed and technical. If you read through our members' answers, I think many of you will walk away with a better understanding than before. And one important thing that I think most members who have responded would like you to take away from this discussion is that higher megapixels don't necessary mean you'll produce better pictures; it really boils down to the quality of the lens and the camera's physical sensors size and quality. Those factors make all the difference between producing a good photo and a bad photo.

I have selected a few answers to start you off in the Q&A section, but there is a lot more information out there, so I highly encourage that you read all of our members' answers. And if you get a chance, dive into the conversation and continue the discussion.

There will be no newsletter next week, so I want to wish you all a happy Thanksgiving! Have a safe and happy holiday!

Cheers!
- Lee

Last week's question
Confusion over digital camera megapixels
QuestionMost manufacturers display the number of megapixels that their cameras have. What exactly is this number? Is it the number of pixels per square unit? If so what is this unit? In film cameras, the size on the film had a bearing on the quality of the final print, particularly enlargements and the larger formats were preferred by professionals who wanted to print large sized pictures. Is there an equivalence in digital cameras and do manufacturers display this? Under what name is this displayed? How much of this is good?

Check out next week's question:
The pop-up window that ruined my PC!
Next week's questionLast summer, a screen popped up on my computer saying that my computer had all sorts of harmful files on it and said that it would scan and remove them. I clicked on "OK" and the software started running and it ruined my computer, blocking my Trend Micro PCillin Internet Security antivirus and preventing any upgrades. I had to get my computer guru to completely wipe out my hard drive and reinstall my applications and what files she could save. She then installed Malwarebytes Anti-malware program the make sure the bad application was wiped out.

She told me to not shut down if this ever happened again, but to run Malwarebytes Anti-Malware and then Trend Micro before shutting down.

On Friday the 13th, a similar thing happened. The bad application said its name was "SWP2009" and offered itself for purchase. I could not delete or minimize it, but was able to shift its screen to where I was able to get to my Malwarebytes Anti-Malware icon. Malwarebytes Anti-Malware responded and started running. I did a complete scan and Malwarebytes Anti-Malware found six rogue files. It deleted them and rebooted my computer. Everything seemed OK, but I ran Trend Micro to be sure. Trend found 13 items, which it deleted. All this took some 4 hours.

Has anyone else encountered similar rogue software? What else can be done? I thought my anti-malware and antivirus applications would stop this, but they didn't. Apparently it was connected to some Web site I opened. I'm running Windows XP Home.
