How do you remove a brontok virus popup?

Hallo,I had this problem with Windows security popup Win32.Brontok ,and i found some tips on net. Well at first go to C://user/application data/google/roaming. When you cant find the directory roaming,the files will be in google directory. Here you can see two files (1. shell.dll and 2.shell.exe (or yifjx15914223.exe). I deleted both this file. Then I installed the program Malwarebytes' Anti-Malware and restarted PC and started in safe mode (press F8 while boot) . I started scanning PC with this program.It were found some changes in registry and some Agent virus ,that were repaired. Then I restarted PC and everything was OK :-).I hope this will help you Hi Milan
