To XP or not to XP . . . ?

[ChiciB1]

35. I Have A MacBook & Will Switch Over, BUT

my grandson who is actually majoring in Computer Technology, don't know exact term, but he told me to download the "driver update" for Windows XP - SP3. He has a Windows 7 that he will install when he finishes college this year so I can still use Microsoft. Right now trying to familiarize myself with MacBook and how it operates, but it's taking time. Lots to learn, and my XP is kind of "old faithful" to me.

A recent thread I started gave me a lot of very helpful information, but that was before I learned he had the Windows 7 operating disk.

My question is this. I'm using Mozilla Firefox as my browser and some have told me that using it would enable me to keep using XP with no problems because of this. I did check out the driver update and was directed to a download used for the Firefox browser. The name was something like slimsilver (not correct) but something like it. I was afraid to complete the process. Still, I would like to try Windows 7 if I find I like it. Don't have extra money to spend on new PC.

Why are some saying Firefox is OK, is it true and should I do the "driver update" since my grandson will download Windows 7 in a couple of months? AND, do I have to do the driver update before the deadline that's tomorrow? Just found out Saturday he had the Windows 7 download available.

Oh, one more thing. With the driver update it's asking me to install AVG, but I read that Kaspersky's, Bitdefender, Avira or G-Data are better. AVG is the only option available, but if I download it can I remove it without any problems and replace it.

I know lots of questions, too little time.
