Unable to login to any websites after cancelled Disc Clean operati

[kjb]

1. Click on Disc Clean as I have been doing on a regular basis for years.
2. Cancelled the operation.
3. When I tried to log on to any website, I received an Error Message
something "Null" and that I may have typed the web address incorrectly.
I cannot connect to any of my Favorites. Not Microsoft, Google,
Yahoo...nothing.
4. What is unusual, is that my home page opens up and,
5. I can run my Norton live update and it connects.
6. I have IE ver. 7

I'm no expert, but I would do a system restore.
