Synaptics TouchPad v6.2

I can no longer access virtual scrolling and tap zones on my mouse pad. I have windows xp on a Dell Inspiron 1200 laptop. I used to be able to access these features, but a while back I got some nasty viruses. They were all removed and I got my computer back in order, but I could no long use some of my mouse options. In the prefrences menu for selecting features I can no longer even check the box. Is my mouse beyond repair, or is there something I can do for it? I have tried to see if I need different drivers, but my computer says that I have the drivers that will work best, and I've had difficulty finding them on the internet for my version, as it is an older one. Can anyone help?

I have 6.2, and this works just fine for me: http://www.synaptics.com/support/drive.cfm
