A quick and easy way to make Chrome web browser more secure:
Go to this url: chrome://plugins/
and start disabling plugins. The number 1 on your hit list is Java, which accounts for 50% of the security issues in the last year. (source: http://www.reuters.com/article/2013/01/14/us-java-oracle-security-idUSBRE90D10P20130114 )
I also disable a bunch of other things like Flash that I just don't see as necessary in my daily browsing, and can be turned on in a .... flash :P
