I Need Help With My Laptop???

I was given a Sony Vaio PCG-731 and want to use it only for the internet and some Mircosoft Works documents. It has a 10GB hard drive, two 64MB sticks, a wireless card, and a Symantec Antivirus program.

I have a couple questions:

A) I want to know how to see how much free memory I have available so I can clear out some unnecessary stuff.

B) I seem to get these pop-up adds telling me my computer 'may' be infected and to purchase these kits to clean out any virus I might have. How do I get this to stop? When I log onto the internet these adds pop-up before my home page does. I updated my Symantec add ran a scan on my entire computer and it found and quarintined a virus/bug. But I still have problems with the adds and pop-ups. Plus my internet seems like it is slower then when I first got it. Any ideas???

C) What extra things can I do to make the internet a little bit faster (would a bigger hard drive help, is it worth it)???

Thanks for any feed back, I appreciate it.

If I am not mistaken, your laptop is USED, VERY used...

It's just the vibe I'm getting...

A) Cleaning out your hardrive:

Go to my computer

Find your Hard Disk Drives.

Find the one you are using (usually C:)

Right click %26gt; Properties

On the pie chart, the blue is the used space and the magenta is the free space.
