its ok. But browsers are still vulnerable. I'll give you one example. A hacker figures out the vulnerabilities of a browser, how to use the browser to compromise your system. He writes a program that checks the browser type and runs something bad. He breaks into somebody's website, puts a program that runs on your machine when you click on the link in a google search. Boom, your hosed. Antivirus does nothing because it thinks its your doing something locally. Email with a link to the website with the program is another way.
Browsers like Firefox have built in protection for that. Phishing and Malware Protection works by checking the sites that you visit against lists of reported phishing and malware sites supported globally by ISP's. These lists are automatically downloaded and updated every 30 minutes or so. If you go to one of those sites you get an ugly red warning message in the browser. IE9 may or may not have that feature.
You can install Firefox and Ad Block Plus without losing any function to IE9. Run them both for a while till your comfortable with a new browser.
