so this is some tips to remove the virus from laptop (windows 7 only):
1. Restart your computer.
2. Press F8 during the bios start up.
3. Choose 'Safe Mode'. (the windows interface gonna look a little odd)
4. Go to my computer. Enter operating system partition. (Usually C:)
5. Enter Users folder and enter administrator folder (Whatever the laptop named) as for example the laptop administrator named 'user' so the folder gonna be at "C:\Users\user".
7. Change the hidden file setting as follow:
8. Now take a look the file in the folder 'user', delete all file with 'Application' type (and any file or folder which look suspicious).
9. Also delete suspicious registry at registry editor HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run (Which is not really necessary).
10. Restart your computer. (Finish)
