Microsoft issued a critical security warning Tuesday 16 December 2008 that a malicious exploit is attacking vulnerabilities in Internet Explorer 7.
The risk is believed to be widespread, given that IE 7 is the latest
version of Microsoft's browser and is bundled with XP service pack 3
and also Vista.
The AZN Trojan, which surfaced the first week of December has the potential of infecting a users
system with a Trojan horse, or a "downloader" that can download other
forms of malware onto a system.
Microsoft announced it will release a security patch Wednesday 17 December 2008 via its automatic update system to patch users computers.
Users can potentially get infected two ways; one is
to visit a malicious Web site that already has the malware installed on
the site or by visiting a legitimate site in which an attacker has
inserted the malicious script to run in the background, leaving
visitors unaware their systems have been compromised.
A lot of Web sites are pushing out this exploit. Some of the infected sites include sites that offer
free wallpaper for mobile phones to sites that feature property and product-related sites.
Microsoft is encouraging users to update their systems once the patch is released Wednesday.
Pure Energy's advice is to ensure that your PC is fully up-to-date and has the latest anti-virus updates downloaded. Run the Microsoft Automated Update as soon as you see it and in the meantime, stay off sites that could potentially be vulnerable or switch to a different browser - for example FireFox.
