Microsoft recommends to upgrade to IE 8
Microsoft has recommended all users who have not yet upgraded to IE 8 from IE 6 version to do so now, since the main reason behind the recent attacks on a number of well-known companies was greatly because of IE 6 security hole. IE 8 users have not encountered any problems during this period, may be because IE 8 has some of the security options turned on by default. For Windows XP users it is also recommended to upgrade to SP3 to further enhance security.
