I have used CNET Tracker ( http://www.cnet.com/techtracker-free/ ). It 
covers a large range of programs and drivers. My concern for security 
directed me to Secunia ( 
http://secunia.com/vulnerability_scanning/personal/ ) to keep my online 
activity programs up to date. I have also used File Hippo ( 
http://www.filehippo.com/updatechecker/ ) that I found to be helpful. 
These programs are all free.
