The Microsoft Malware Protection Center reported a security hole in all versions of Internet Explorer, with 50% increases in reported infections in just one day.

The vulnerability, which exists in all versions of the Microsoft browser, including IE5.01, IE6, IE7 and IE8 Beta 2, has so far been exploited only by attack code that targets IE7, the most widely-used edition.

The best defense to security issues is

•    You should always exercise caution when browsing and try to go to sites that you trust.
•    Always to keep your browser versions up to date by going to “Windows Update”
•    Use virus and spyware scanners regularly.
