I think I downloaded software with a surprise attached! Anyway my browser keeps opening new tabs. My AVG keeps finding viruses out of the blue without a scan being run.

I also ran Avast, and it detected Win32:Kavos.

Anyway, these weird files appeared recently, which will not delete:

kamsoft.exe
urretnd.exe

and everytime avg tries to quarantine this file cdaudio.sys i get a blue screen. stupid.

Anyway, just need help or a cure for it.

Please download ComboFix from BleepingComputer.com

Rename ComboFix.exe to commy.exe before you save it to your Desktop

• Disable your AntiVirus and AntiSpyware applications, usually via a right click on the System Tray icon. They may otherwise interfere with our tools A guide to do this can be found here
  
• Click Start then copy paste the following command into the search box & hit enter: "%userprofile%\desktop\commy.exe" /stepdel
  
• As part of it's process, ComboFix will check to see if the Microsoft Windows Recovery Console is installed. This will not install in Vista. Just continue scanning, and skip the console install.
  
• When finished, it shall produce a log for you. Please include the contents of C:\ComboFix.txt in your next reply.
