I have known yesterday that IE have been used by cyber criminals taking advantage of the browser bug to inject a trojan into the unsuspecting user computer to harvest personal data.
Microsoft need to be proactive in dealing with flaws of its software before cyber criminals find it out first. Almost always though, Microsoft is the last to know about the bugs in its software.
I remember some few years back, the Outlook has been the target of the “I love you” virus which affected millions of computers worldwide.
I don’t use Internet Explorer (I used Firefox) and seldom use Microsoft software, (I used Linux) unless I don’t have the choice.
If you are using IE particularly for internet banking and other transactions, it is a must to update your browser now.
