I had some virus problems that I fixed. I went to Firefox to open it up but it would not open up saying that it crashed unexpectedly and I had to send report which I did. I tried fixing it but did not work. So I uninstalled Firefox thinking I would be able to go to Internet explorer and download Firefox then and make it default browser. So I went to internet explorer and tried starting it but it wouldn't. So I have been trying to make it default browser but it will not work. I have tried so many ways.
