The only security I have running or ever need running is is an antivirus. I actually went a full year and still never got infected. My setup goes like this :

Avast (all shields high and PUPS enabled)
Windows 7 Firewall with Advanced Security
2WIRE Gateway w/NAT
Google Chrome w/ABP,DNTM and LP
On demand scans with MBAM once a month

I also make a complete disk image about twice a week. A disk image is the best insurance you can have. I was a huge BitDefender fan but the program is way too buggy and not customizable. 12 years and going and never been infected.

polonus …I saw your post and yes its overlapping regardless of detection rates. Avast’s Web Shields and BitDefender’s Traffic Light are both examples of web filtering and or shields. They both do the same thing therefore it is called over lapping security. Man I will never understand why people are so paranoid. I could care less if I got infected. Why? Cause I can just mount my disk image and within 45 min I am up and running like nothing ever happened.
