The Short Answer

While some viruses might install toolbars, it's not typically something that viruses do. It's possible that the maker of the virus gets paid per toolbar install (in the end it's all about the money) but as long as the toolbar itself is legit, the maker of the toolbar will probably figure this out and ban the maker of the virus. Toolbars, or other some such browser addons, can make money via advertisement. Like I said, though, chances are that the toolbars you have are installed by legit programs that you installed yourself and just clicked accept on every button. Viruses will nowadays try *not* to be detected so the maker can use your system longer (for instance: they might use your computer to send spam, mine bitcoins or DDOS attacks).
