Earlier this week, tech blogs began urging users to switch to a browser other than Internet Explorer. The reason? Well, several versions of IE (7, 8, and 9) have been found to have a major security flaw. This hole allows hackers to get complete control of vulnerable systems which, according to several forums, are running either Windows XP, Vista or 7.

The flaw in Internet Explorer is exploited by a piece of software that installs itself on the user’s computer after they’ve visited a malicious site. Until the issue is resolved by Microsoft, Internet Explorer are being encouraged to switch to another browser, like Google Chrome or Mozilla Firefox, or upgrade to IE 10 (currently available to preview) which does not contain the same flaw as earlier versions.
