Avast Online Security 8.0.1488 add-on is really needed only for Internet Explorer. Other browsers are not tied to the operating system as IE is, so any damage to these will tend not to affect the operating system. Not so for IE; damage there can/will affect Windows. IE is also very proprietary by design, and add-ons such as AdBlock Plus will not run on it, but will on third-party browsers. So, third-party security add-ons are just not as readily available for IE as they are for other browsers because of Microsoft’s proprietary design.
avast! does use IE settings to communicate with its’ servers, btw.
