Brontok.N

Few days back i discovered that some strange things are happening in my pc in windows. Sometimes applications were closing down automatically . Also i was not able to open cmd. I ignored for 2-3 days. Then i saw a text file named BacaBro in C:\. When i opened it, a dos window appeared with some text. I searched on google and found that it is Brontok.N virus. I spent whole night reading about it and downloading the removal tools.

Brontok.N spreads through email attachments. Still i m not able to figure out how it entered in my pc . It installs itself in the Registry. It disables the Windows Registry Editor and modifies explorer settings. It removes the option of “Folder Options” or doesn’t allow u to open it so that the hidden files, where it is concealed, are not easily accessible to the user. Does not allow u to open cmd shell. Also sometimes applications close automatically and it blocks access to antivirus websites. The code for the virus is written in c++ .

First i downloaded removal tool from microsoft website. It removed the virus. Everything was working but when i rebooted the pc, the virus appeared again . Then i installed this removal tool. Finally my pc is free from virus \:D/
