Wipe your HD of all infected code using Diskpart from Win7 DVD Command Line:
Clean and Clean All with Diskpart Command
DISKPART At PC Startup
After wipe, close the Command Box, click Install Now, choose Custom Install, then Drive Options. Create partition(s) as you wish and Format before install, following illustrated steps given here:
Clean Install Windows 7
The installer will issue a 100mb System Reserved boot partition which conveniently places the
Repair Console (normally only on the DVD or Repair CD) on the F8 Advanced Boot Tools menu.
The installer is mostly driver-complete, with newer arriving quickly via optional Windows Updates. Just in case, have your Wireless driver on flash stick or CD so you can get online quickly. Then
enable hardware driver auto-updating and check for optional Updates several times.
If you're using Upgrade version, leave Product Key box blank during install, then afterwards use the quick registry edit given here to activate Upgrade version on a cleaned HD:
Clean Install with a Upgrade Windows 7 Version
Any drivers still missing in Device Manager can be found on the Support Downloads webpage for your model computer or device.
Driver Install - Device Manager
Install updates and then programs slowly over time to gauge performance changes after each. Don't let any programs write themselves into msconfig>Startup as they slow startup, become freeloaders on your RAM/CPU and can spy on you. I only allow AV and gadgets.
Startup Programs - Change
Use a lightweight free AV like MS Security Essentials which works perfectly with Windows 7 Firewall.

Finally save a Windows 7 Backup image externally so you never have to reinstall again, just reimage the HD (or replacement) using DVD/Repair CD with the stored image.
