Possible Rootkit Infection; Atapi.sys?

I suspect that, if you have a Boot CD, like Ultimate Boot CD for Windows (or can make one on another machine), you could probably put the registry entries back. Those are five security violations that could never happen on a secure operating system. I was very surprised, but I have yet to actually take action because I think I just read that atapi.sys might actually a required system file. I still get an occasional BSOD. http://ircdhelp.org/possible-rootkit/possible-rootkit-in-the-atapi-sys-file.php

There are some (unsupported by Microsoft) ways to put Windows recovery systems on memory cards and USB memory sticks. They just want their computers to work out of the box without much effort. Scan weekly if you have high Internet use. All these people - even at major banks and even at the AV vendors - getting infected with rootkits and trojans and they didn't have a clue.

CD is more foolproof. you can at least get back to "now" if it doesn't work. After cleaning, you will need to disable the System Restore function For Windows XP. It took a while for AV products to find and remove them on a active system.

After I was able to uninstall KB977165, everything returned to normal and I still has a clean machine. check over here Does anyone hear any other bell tolling? Microsoft have their Patch Tuesday and everyone scrambles to get their updates. Second time I ran it everything was fine.

Until that mentality changes, we will continue to have these issues. The problem is people don’t want to be bothered. Alex F Atapi.sys is shown as specious modification when it is infected MOHANRAJ R gives me a blue screen once a day elvis This file is his comment is here I don't know whether he, too, had a warning about atapi.sys.

Microsoft Security Essentials detects it on Windows 7 and seems to disinfect it, but I'm not sure if it really has succeeded. I tried Start Windows Normally, and then I tried Go Back to Last Known Good Configuration, and then I tried Safe Mode. But once this is done and the trojan resides on the local machine, the following happens. 1.
