Who told you to do that ?
first you should run tdsskiller form kapersky
when clean install and run malware bytes
if problems persist try combofix. (warning, this could make windows not boot anymore)
if all went well you have to fix boot record (here's a nice page that will help you http://peterhallam.com.au/dos-alureon-a/)
If this didn't do the trick
go to http://www.bleepingcomputer.com/
and seek help there as their are chance you will not be able to recover from infection and then windows reinstall is the only option
