Norton Utilities 15 Messed Up My Web Browser.

Dear people of the Norton Community,

 

I looked at my system status in Norton Utilities 15 and it claimed that my system was "low". I clicked the scan button and the program started to delete files. It APPEARED to be deleting files from some folder involving the internet. When I opened up youtube, I found the layout to be all messed up. It appears that many other sites are messed up too. I'm using Firefox, and have tried re downloading it. I learn that the online messaging  Norton support system is just me, talking to a bot, which proved to be unhelpful. I looked all over the web and couldn't find anything helpful. I bought this product and as far as I can see it was not worth my money.

 

If anyone knows how to fix it please reply.

 

Sincerely,

Petro
