Hi AVG Team,

Recently when i am browsing the internet using my IE11 browser, all of a sudden a pop up came and my browser got closed and the IE has disppeared even from the tool bar. Whenever i search using the word "Internet Explorer" , it opens GOOGLE CHROME  browser , with some default search screens which i never set , instead of IE , i am not sure if IE11 got uninstalled which should not happed as it comes default with system . Thereafter i have installed AVG pro version and it scanned and found 22 threats , and they were removed. Now my questions are as below
1. How can i get my IE11 browser back?
2.How can i remove the default search which are getting launched immedialtey when i open a new browser ?

Thanks in advance
