Google and the Berkeley researchers found that ad injectors are now available on all major platforms and browsers. Out of those 5 percent of users that have at least one installed, one-third actually had four of them running simultaneously and half were running two. Clearly, there is a group of users that is a bit more prone to catching one of these than others.

I've seen users with a visible browser screen of less that 3cm (that's an inch and 3/16 to you colonials) such was the amount of "toolbars".
Didn't do a lot of online shopping to be fair.

I'd have thought it'd be more like 15%. If you were to look at Bing, and particularly the IE users coming to Bing from default settings, I'd bet it'd be higher than 20%.
