  • When i tried to search DisableRegistryTools i am not to find it even i have tried your CMD trick that is also not working i am getting some REG DELETE Error.

    I think this trick work in Windows XP.

    but i will say u are doing really good work i appreciate.

  • @moneymoney first of all let me ask you a basic question. Is you PC infected with brontok virus? If the answer is no then neither of the two commands I have mentioned work on you PC, coz the string value DisableRegistryTools doesn’t exist in your registry. Moreover the search shouldn’t be done for DisableRegistryTools. The search I have mentioned is to list all the .exe files on your PC. So in the field that says ‘Type all or part of the filename’ in Windows search you have to give *.exe as the search term. Even if that string value does exits in you registry how can you find it on Windows search? Windows search cannot find registry keys or values. So DisableRegistryTools is not what you have to search for. Hope you have understood. Let me know if your computer is infected with this brontok virus and found this trick not working on your PC, so that I can come up with the solutions that suits you.
