Hey, this is the second time I've been infected with either a PDF or a Java.exe exploint while browsing the web. The attackers generally exploit adservers and deliver the malware with a pdf files or a java exploit. The very serious problem with this is that a user doesnt need to confirm the execution of the executable and even advanced users are left vulnerable if they allow pdf files to be opened in the browser. I have set that all pdf files are to be downloaded but I am not sure if this will be sufficient in combating these attacks. This occured with Java 6 and Reader 9.1 The infection eventually or immiedietly installed the TDSS rootkit in the iaStor.sys driver. ComboKit was not able to get rid of the rootkit and Kaspersky's tool was not successful either. I stupidly overwrote my iaStor.sys file with avenger with a backup but this permanently broke windows. Replacing the iaStor.sys with a iaStor.sys from another windows or from Intel's archive doesn't fix windows. Apprently you cant just overwrite driver files? I had to reinstall Windows Anyway, please, please work on these threats because they are clearly the future of malware and the attack vector is superior to asking a user for permission to execute.
