No it won't. It may cause some registry errors though! There's a very good registry cleaner that I've been using for quite awhile. It's free and not so powerful that it will get you into trouble! The Windows Registry is the heart and soul of the operating system, and if you get some problems started in the registry, it can turn your computer into a paperweight! It's called Auslogics Registry Cleaner. Link provided if you care to look.

Just be careful with Norton! I had problems with it years ago and received little help from their technicians. They usually took at least 3 to 4 days to get back to you to try and solve a problem! You don't need to spend a lot of money on security software. Microsoft Security Essentials, Malwarebytes, SUPERAntiSpyware, Avast and others are free and very good unless you're reckless at the web sites you visit. Hope this helps! Good Luck!
