Spyware or virus?

I let my sister use my laptop for awhile and she downloads stuff. Well I got a virus or something because in all my web browsers whenever I google something, about 80% of the time I get redirected to some attack site.
When I first open up my browser it will open the home page then once in awhile it will open another tab and go to freewebsitesurvey.com

I have windows 7 and I don't care about none of the files on my computer.
I tried inserting the disc and reinstalling it but whenever I try it says their is not enough space to store windows files, but my drive has about 40GB free.
Then when I try to do a custom install, it doesnt list my hard drive and says i need to find device drivers when before it would list them.

I ran AVG and McAfee anti virus and both found nothing.

If you don't care about any files on the computer and want to complete scratch the HDD and reinstall, then grab a hexeditor that can edit raw devices (I'd recommend WinHEX for that), open the HDD (not a parition / drive letter, the whole disk) and overwrite the first 512 bytes with all zeros.

Reboot and try again.

This will wipe all partitioning information and let the HDD appear completely blank.

Some bootable media, yeah.
Win CD/DVD, USB with Win setup on it, something like that.
