ABP + NoScript = Safer Browsing

Web browsing is the primary vector for malware infection.

By making your web browsing experience safer you can significantly reduce your overall risk of infection

One way you can do this is by using the Ad Block Plus and NoScript addons for Mozilla Firefox:

NoScript essentially works by blocking all scripts except those from whitelisted domains (ones you give the ok to)
-It will by default only allow scripts to run on very few websites and it is up to you to decide which ones you think are safe
->Admittedly this gets annoying especially when you first start but if you want an extra layer of protection it is worth it

Ad Block Plus works by creating a blacklist of advertisements on the web
-The danger with advertisements is that some vendors do not regulate content well and sometimes serve so called "malvertisements" which will attempt to infect your computer.  If you simply block advertisements then your risk of getting a malvertisement will go down.
->I have seen computers that have been infected by malvertisements served from a variety of ad networks on a range of websites. I believe there was actually a malvertisement on the New York Times main website a while back.
->The drawback of Ad Block Plus is that it might block advertisements that you are interested in viewing.  You can disable it on pages of your choice

So when looking at the two together:
-NoScript will minimize your risk significantly and only run scripts on websites of your choice
-Ad Block Plus serves as something of an extra layer of protection for websites you chose to run scripts on.  If such a website is in a position where it will infect you it is probably due to a malvertisement so Ad Block Plus would likely protect you in those cases.

**Note**
Running ABP and NoScript together is not guaranteed to make your computer impervious to browsing attacks.  Common sense is still your best tool and should not be neglected.
