After how I delete all files associated with the Internet explorer,all the browsers lost the sound of alerts that come. For example, personal messages in social networks: vkontakte - vk.com.

Or when a message arrives, it does not appear that it has come. And that in the message box there are notifications - for example, the number of messages, it is necessary to click on the home button or the start page, so that the data is updated constantly, but it happens that the number of messages is displayed. There is no time for doing it.



Perhaps this error causes not only the removal of standard browser files.
