One in four don't clean their stinky old browsers - especially Firefoxers
Nearly one in four netizens are using outdated web browsers and are therefore easy pickings for viruses and exploit-wielding crooks.
The average home user upgrades his or her browser to the latest version one month after it is released, according to a survey of 10 million punters. Two thirds of those using old browser software are simply stuck on the version prior to the latest release - the remaining third are using even older code.
Internet Explorer is the most popular browser (used by 37.8 per cent of consumers), closely followed by Google Chrome (36.5 per cent). Firefox is in third place with 19.5 per cent. Firefox users tend to be the worst for keeping up to date with new software releases, according to the survey by security biz Kaspersky Lab. The proportion of users with the most recent version installed was 80.2 per cent for Internet Explorer and 79.2 per cent for Chrome, but just 66.1 per cent for Firefox.
