"A fast spreading of the code has to be feared", advises German government regarding the bugs that are commonly troubling PCs and making them more vulnerable to hacker attacks.

Explaining further about the bugs that are behind the attack to the security of the PCs, Microsoft exampled primarily about the computer virus creators like the Poison Ivy trojan, which it says can severely exploit the security hole in Internet Explorer, thereby taking control of PCs that visit the malicious website.

The German government's Federal Office for Information Security, or BSI is well aware of all the targeted attacks and how the web surfers are being lured to websites, where hackers have already planted viruses.

Thus with an aim to aware more internet users with some protection measures, BSI has advised the Internet Explorer users to switch to an alternative browser until they are informed with a security update.

The flaw came to light last week when Luxembourg-based security expert Mr. Eric Romang noticed his PC to be infected by Poison Ivy.

Till any profound solution is found, Microsoft has released a temporary software fix called the Enhanced Mitigation Experience Toolkit to tackle the issue of the newly discovered bug, which it advises to its entire user base to download.
